1. Summary
A
Workshop
entitled
“Biomaterials:
Perspectives
and
Possibilities”
(http://www.uom.ac.mu/polymer/workshop/) was held at the University of Mauritius, Reduit,
Mauritius, from November 30th, 2009 through December 4th, 2009. The workshop was funded
by the National Science Foundation and organized by Professor David Kaplan of Tufts
University in collaboration with Professor Dhanjay Jhurry of the University of Mauritius. The
focus of the conference was on the state of the art in biomaterials research and each of the five
days focused on a specific, unifying theme; biomaterials, regenerative medicine, drug delivery,
nanotechnology/biosensors, and government/industry issues in the Indian Ocean region
(Appendix A). An accomplished group of faculty was recruited to run the workshop and various
Mauritian Ministries were in attendance to facilitate a productive meeting and assess the long
term impact of biomaterials research (Appendix B). Participants were invited from surrounding
regions, including Europe, Africa, Southeast Asia, India, Australia and related environs
(Appendix C). This workshop identified many of the needs of the Indian Ocean Region as it
applies to multinational biomaterials research and collaboration. The conference participants
committed to build long-standing impact for this initiative through follow on planning and
programs so that a sustainable set of opportunities can be provided for the region as biomaterials
research grows over time.
This involved partnerships between government, industry and
faculty.
The major outcomes of the workshop were three-fold:
1. The results from the conference are being disseminated via the development of a graduate
level course in Biomaterials for the University of Mauritius that will be jointly taught by
faculty from the United States, rather than through traditional conference proceedings
(Appendix D). We thought this outlet would better serve the promotion of biomaterials
education in the region.
2. The initiation of collaborative research efforts between conference participants from Africa,
the Indian Ocean Region, and the United States (Appendix E).
3. The planning of follow-on needs to develop student exchange programs for research, training,
and education in biomaterials research between the University of Mauritius and various
universities in the United States.
The conference provided participants the opportunity to learn more about the current global state
of biomaterials research and the future directions of the field as a whole. The primary focus was
1
on the needs, opportunities and future plans for multinational collaboration in biomaterials
research between the United States, Mauritius, and the broader Indian Ocean region.

2. Background:
Perhaps more than any other field, biomaterials brings together researchers from across diverse
disciplines and backgrounds. The workshop, Biomaterials: Perspectives and Possibilities, built
on this, with the objective of developing an interdisciplinary research, education and training
program, focusing on the engineering of biomaterials for use in tissue engineering, drug delivery,
nanomedicine, and biosensing. Biomaterials have a long history – dental implants are arguably
the earliest examples, with the Mayans creating teeth from seashells for bone integration. Now,
biomaterials are used in a broad spectrum of applications, from growing cells in culture to
‘biochips’. They are specifically engineered to have unique properties that interface with
biological systems for evaluation in the body and the environment; drug delivery therapy; and
the replacement of diseased or injured tissue. Biomaterials substantially impact human health,
with nearly 20 million people having had functional organ replacement in 2000 [Ratner, et al;
2004]. And as the overall global population continues to age, demand only will increase.
Recent advances in biology and chemistry have brought fresh energy to the field in the areas of
implantable medical devices, tissue engineering, drug and gene delivery, imaging agents,
bionanotechnology, and biosensors. Biomaterial options are broad, and include metals, ceramics
and glasses, degradable and non-degradable synthetic polymers, and biological polymers, both
native and genetically engineered. While the design properties of these biomaterials have
advanced, future needs include more diversity in chemistry and structure, and the ability to
match specific materials to tissues and repair needs. It is important that biomaterial features
include control of material structure, chemistry and morphology, biocompatibility, controllable
rates of degradation, processability in biocompatible solvents, modification for additional
function and optimization, and a wide range of mechanical properties. Biomaterial-biology
interface issues include protein adsorption, cell interactions, blood compatibility, calcification,
inflammation, immunological responses, allergic responses, hydrolysis, physical irritation, and
toxicology.
Biomaterials: Perspectives and Possibilities was co-organized by Professor David L. Kaplan,
Tufts University and Professor Dhanjay Jhurry, University of Mauritius. Dr. Kaplan is Professor
and Chair of the Biomedical Engineering Department at Tufts, and focuses on biopolymer
engineering to understand structure-function relationships, with emphasis on studies related to
biomaterials and functional tissue engineering. He is also the Director of the NIH P41 Resource
Center on Tissue Engineering – a program that facilitates extensive national and international
research, training and related needs in the field, covering biomaterials, stem cell biology,
bioreactors and related needs. Dr. Jhurry is a Professor in the Chemistry Department and group
leader of the Polymer Group Research Program. His program develops
biodegradable/bioresorbable polymers for use as medical devices such as cardiac valves, stents,
wound dressings, and drug delivery vehicles. He is a leading researcher in the region and has
well-established relationships with other biomaterials researchers.

3. Summary of Lectures:
Summary of Day 1 (Nov 30, 2009)
Biomaterials
The underlying theme for day 1 of the workshop evolved around biomaterials and the regulation
of cell function through biomaterial design. Four long talks, two short talks and discussions
covered a broad scope of the field – design of “smart” (functional, custom-designed)
biomaterials, biophysical (molecular, hydrodynamic, mechanical, electrical) interactions between
the biomaterial and the living cells, and the utilization of biomaterials for tissue engineering. One
unifying theme that emerged in all talks was the need for biological principles for biomaterial
design. Another theme was that of “dynamic reciprocity” of the interaction between the cells and
their matrix.
Dr Kaplan (Smart biomaterials) reviewed biomaterials inspired by biology and designed for
regenerative medicine, with respect to the regulation of cell function, formation and turnover of
extracellular matrix, metabolic processes, and tissue assembly. The emphasis was on collagens and
silks. The emerging possibilities that were discussed included the development of fully resorbable
implantable medical devices, the use of biomaterials to enhance prevascularization, conduct signals,
and build systems for use in space missions.
Dr Kuo (Mechanical factors) discussed mechanical signaling in the context of cell-biomaterial
interactions, for a variety of tissues and applications. Mechanoregulation of cell fate, tissue
development and function was emphasized as a critical design requirement for biomaterials utilized
to guide and support tissue development. The application and generation of mechanical forces were
discussed for a range of load-bearing tissues, with particular emphasis on tendon development and
tissue engineering.
Dr Vunjak-Novakovic (Tissue engineering) reviewed the cultivation of fully biological, functional
human tissue grafts by an integrated use of repair cells, biomaterial scaffolds and bioreactors.
“Biomimetic” approach to tissue engineering and the need to restore normal tissue function, were
emphasized. Custom-design of biomaterial scaffolds was discussed in the context of the need to
“instruct” the cells to differentiate into a functional tissue structure. The current challenges of the
field were also identified.
Dr Burdick (Modifications of biomaterials) covered a range of techniques for modifying the
composition and structure of a variety of materials for biomedical application, from metal and
ceramics to hydrogels and biodegradable polymers. The talk emphasized the importance of
biomaterial design for physicochemical interactions between the cells and the scaffold, and the
importance of controllable and degradable materials. The introduction of functional groups designed
to guide cell function was discussed.
Dr Bezuidenhout (Vascular grafts) discussed structural requirements for synthetic vascular grafts
that can be endothelialized in vitro with a confluent layer of cells. Strategies for the establishment of
nonthrombogenic properties and vasculogenesis were outlined.
4
Dr Ripamonti (Bone formation) discussed how some porous biomaterials induce the formation of
vascularized bone by mesenchymal stem cells when implanted in an ectopic site, by following
mechanisms involved in early bone development.
Summary of Day 2 (December 1, 2009)
Regenerative Medicine
The underlying theme for day 2 of the workshop evolved around regenerative medicine and a variety
of recent advances within this area. Four long talks, one short talk and discussions covered a broad
scope of the field – system strategies and stem cells in regenerative medicine, microengineered
hydrogels that can be used to assemble tissue structures, bioreactor systems with an emphasis on
musculoskeletal tissues (e.g., bone and cartilage), and advances in biomaterials for use in
regenerative medicine. The primary themes of the day included recent advances in various
components of tissue engineering, including the cells, biomaterials, and culture environments and
using these concepts to advance the field and clinical translation of these materials.
Dr Gerecht (System strategies and stem cells) reviewed how stem cells are finding utility in the field
of regenerative medicine, including interactions with biomaterials. She presented on basic concepts
related to cell sources for tissue engineering and how they can be utilized in regenerative medicine
strategies. Vascular regeneration was used as the model system to illustrate how these decisions are
made and how stem cells can be used in these systems. Approaches included a range of hydrogels
based on alginates, hyaluronic acid, and dextran with modular properties to obtain desired results.
Dr Khademhosseini (Microengineered systems) discussed the development and application of
microtechnology for regenerative medicine applications. This work was divided into the areas of
microwells, “bottom-up approaches”, and “top-down approaches”. These approaches are useful for
the screening of cellular microenvironments, as well as for the assembly of tissue structures. The
focus was on controlling embryonic stem cell differentiation, as well as the development of cardiac
tissues.
Dr Vunjak-Novakovic (Bioreactors) reviewed the application of tissue engineering principles for the
regeneration of a range of musculoskeletal tissues, including bone, ligament, and cartilage growth.
These approaches used a range of biomaterials (e.g., poly(glycolic acid), silks), bioreactors, and
media formulations to engineer tissues. It was pointed out that these tissues are quite different and
need a unique approach (e.g., choice of biomaterial) for adequate engineering and repair.
Vascularization was identified as an unmet need for many tissue engineering constructs.
Dr Burdick (Advances in Regenerative Medicine) covered recent advances in the development of
advanced biomaterials for regenerative medicine. Materials that have excellent control in both time
(via degradation) and space (via patterning) were discussed, as well as how this control can be used
to manipulate formed tissue properties and cellular behavior. Combinatorial syntheses and high
throughput screening technology was also covered for the development of a wide range of polymeric
materials and to identify molecules that can influence stem cell behavior.
5
Dr Ripamonti (Bone and Clinical Translation) provided information on the translation of therapies
related to bone regeneration from animal studies to the clinic. Particularly, his lecture focused on the
limitations of animal models and the differences in observed bone formation between what is
observed in animal models and what is found in the various models.
Summary of Day 3 (December 2, 2009)
Drug Delivery
The presentations on day 3 of the workshop focused on drug delivery, which included delivery of
chemotherapeutics, growth factors, cytokines, diagnostic markers, and DNA-based therapeutics. A
wealth of design in drug carriers, gene carriers, theranostics, and nanoparticle decoration highlighted
the continuing and important role of biomaterials can play in this field. The talks also underscored
the ample opportunity for innovation to tackle therapeutic challenges.
Dr. Jhurry (Nanoparticle Drug Delivery Systems) reviewed the rationale and fundamentals of
controlled release and covered the main types and characteristics of nanoscale drug delivery systems
with particular attention paid to polymer-drug conjugates and polymeric micelles, and discussed the
correlation of the physicochemical properties of these drug delivery systems with their biological
performance. The lecture also discussed the challenges and opportunities of applying innovative
polymer chemistry and materials science to develop complex multi-functional nanoparticles.
Dr. Leong (Cancer Therapy) discussed the design of bioadhesive microspheres for intravesical
delivery to improve efficacy against bladder cancer and the development of polyanhydride (Gliadel)
for intracranial implantation to treat glioblastoma multiforme. The development and performance of
autologous formalin-fixed tumor vaccines for hepatocellular carcinoma and glioblastoma multiforme
in clinical trials were shown. The lecture also emphasized the promise of immunotherapy against
cancer, with discussion on how delivery technologies could help advance the field by effectively
presenting co-stimulatory signals to the antigen presenting cells for stimulating optimal antitumor
immune response.
Dr. Lecommandoux (Polymer Vesicles) reviewed the important features of polymersomes in drug
delivery. Formed by self-assembly of block copolymers, these polymersomes excelled in control of
size, shape, stability, pH-sensitivity and versatility in comparison to lipid vesicles. The lecture
discussed in details the interesting features of polysaccharide and polypeptide-based block
copolymers in drug delivery. The presentation also showed the recent development of magnetic
polymersomes, which exhibited exciting potential as theranostics in tumor targeting and tumor
regression studies in animal models.
Dr Leong (Gene Therapy) discussed the design and application of polymeric gene carriers for DNAbased therapeutics. After a discussion of the performance of chitosan and polyphosphoesters in
genetic immunization and gene medicine applications, respectively, the talk focused on engineering
polymeric carriers that can release an intact DNA at the optimal time and subcellular compartment.
The lecture covered the combination of material design, novel imaging techniques, and sophisticated
in vitro model systems to facilitate the rational design of polymeric gene delivery vectors.
6
Dr. Klumperman (Alternative to Pegylation) discussed the use of Reversible AdditionFragmentation chain Transfer (RAFT) to introduce chain end functionalities into proteins. The
presentation highlighted two examples, the first on the conjugation of poly(N-vinylpyrrolidone)
(PVP) to a protein, and the second on the use of star-shaped PVP for the synthesis of hydrogels.
Dr. Bhaw-Luximon (Oligoagarose-g-PCL) presented the synthesis and characterization of
amphiphilic copolymer obtained from grafting enzymatically degraded agarose onto PCL. The
copolymer formed micelles and showed promising properties in terms of small size, reasonable drug
loading, cost, and favorable release kinetics. The oligoagarose-g-PCL compared very favorably to
other micellar delivery systems with respect to delivering ketoprofen.
Dr. Narain (Carbohydrate-based nanostructured materials) discussed the design of biologically
relevant glycopolymers and glyconanoparticles and their characteristics with respect to toxicity,
biomolecular recognition, cellular uptake and gene delivery applications.
Dr. Ateh (Intrajan Delivery Platform) discussed a proprietary intracellular drug delivery platform
developed at Barts and the University of London. The presentation showed the uptake of
microparticles by non-professional phagocytes and the modulation of this process by a specific
protein applicable to cancer.
Summary of Day 4 (December 3, 2009)
Nanotechnology and Biosensors
The presentations on day 4 of the workshop focused on nanotechnology and their applications to
biosensing and regenerative medicine. The talks started by focusing on the use of nano and
microscale technologies and hydrogels for biosensing. The topic of electrospinning and its
application for regenerative medicine was then described. The talks later in the day focused on the
use of nanotechnology for global health applications such as tuberculosis was discussed. Finally the
future applications and needs of nano and microscale technologies for regenerative medicine and
tissue engineering was discussed. The day also included poster presentations by the students from
Mauritius.
Dr. Guiseppi-Elie (elecroconductive hydrogel biosensors) discussed the development of
electroconductive hydrogels for biosensing applications. He discussed the point of making different
kinds of electroconductive hydrogels for various applications such as in vivo brain stimulation. He
also discussed the opportunities in battlefield trauma as well as pediatric cardiac care. After giving
a broad overview of the area of biosensing, Dr. Guiseppi-Elie discussed the development of biosmart
networks of biosensors made from various polymeric hydrogels that can respond to various types of
materials. The entire device should be handheld and fabricated into devices. Thus the device can
be implanted as an in vivo biosensor where all the components are integrated. The implantable
devices can be used to detect various entities like pH lactate and glucose concentrations. In some
variations there are hydrogels patterned on electrodes which can then be used to detect the specific
entity. The hydrogels are dispensed on the electrodes by a bioprinter and can then be crosslinked
and used.
7
Dr. Bowlin (Nanotechnology processing) presented on the use of nanoscale processing for making
fibers of various types of polymeric biomaterials. He stated that the tissue engineering has
similarities to fabricating fabrics. Thus the goal was to replicate the fabric-based tissue engineering
scaffolds that mimic the natural extracellular matrix. Electrospinning had been developed a long
time ago but only recently it has been used for tissue engineering. The process of electrospinning
was described. Various polymers were spun and used as scaffolds for vascular and bone tissue
engineering. Examples that used natural polymers like collagen, silk and fibrinogen were described.
Electrospun scaffolds showed much improved performance due to their biomimetic properties.
Interestingly, the mechanical properties of the scaffolds could be easily controlled over a wide range
of properties and the fibers could be spun randomly or aligned based on processing conditions.
Dr. Swai (Nanotechnology for Tuberculosis) presented a talk on the use of nanotechnology and drug
delivery for the treatment of tuberculosis (TB). TB is a high killer in Africa due to co-infection with
HIV which reduces immunity. Dr. Swai presented about the challenges in the conventional oral
drug delivery systems and presented nanomedicine as a potentially powerful method of overcoming
these challenges. She discussed her work on the development of nanoscale systems for delivering
drugs for TB.
Dr. Khademhosseini (Future needs of micro/nanoscale technologies) discussed the current and the
future directions of the use of nano and microscale technologies for cell-based biosensing and
regenerative medicine. He divided the talk into different sections such as surface modification,
microarrays, microfluidics, mechanics and tissue complexity and for each section he discussed the
current state of the art and the future needs of the area. It is clear that much progress has been made
and new nanoscale technologies have started to make a great deal of impact in enhancing the areas
of regenerative medicine and biosensing. As an example, microarrays of thousands of polymers
have been generated for optimizing the differentiation of stem cells. In addition, novel nanoscale
materials have been generated with enhanced mechanical properties. In addition, Dr.
Khademhosseini discussed the fabrication of electrospun scaffolds with elastomeric properties by
mixing PGS and PCL mixtures. Work was also discussed at the interface between microfabrication
and cell culture. In particular various technologies to pattern cells and generate patterned co-cultures
were discussed.
Dr. Kistamah (Cyclodextrins) described the use of cyclodextrins in textile industry. Cyclodextrins
can make hydrophobic cavities that can be used to deliver molecules to textiles. Dr. Kistamah also
described the role of the cyclodextrin on the photostability of the bleached wool and cotton fabric.

Summary of Day 5 (December 4, 2009)
Broader Impact – Government and Industry Issues in the Region
The topic of interest for day five was the broader impact of biomaterials research, including
governmental and industrial issues within Mauritius and the Indian Ocean Region. Talks were
given by various industry representatives as well ministries of Mauritius as to the future steps
that the country is taking to convert from a labor-intensive economy to a knowledge-based
economy. Presentations ranged from current research in Mauritius on biomaterials, awarenessraising of science and technology, student exchange with the USA, and new industrial initiatives
to promote science, technology, and industry for Mauritius
Robindro Ghose (Ministry of Industry, Science, and Research) spoke about Mauritius’ strategy
for seeking higher levels of economic growth. This will be done by focusing on science,
technology, and industry in order to make a transition from a labor based economy into a
knowledge based economy. Labor prices in Mauritius are no longer competitive with the global
market so by virtue of necessity Mauritius must pursue an entrepreneurial and innovation led
economy by attracting high tech investments. Several initiatives are already underway which
attempt to synergize academia, industry, and the public sector. These include the promotion of
bioinformatics, stem cell research, medical devices, agriculture, and renewable energy.
Dr. Arjoon Suddhoo (Executive Director, Mauritius Research Council) emphasized that
Mauritius needs to do research which has high commercial value. Many policies have been put
9
in place to foster these endeavors and among them is the National Innovation Fund which
promotes students and industry professionals to pursue emerging technology sectors. Priorities
include marine pharmacology, geothermal energy management, and science/technology
education.
Ashokabose Moorgawa (Tertiary Education Commission) stated that the main goal of the
Tertiary Education commission is to provide resources in the form of scholarships and
fellowships for Mauritian students. The ultimate goal of this commission is to promote scientific
research in Mauritius. Mainly, these funds will support a four year PhD program and a 2 year
post-doctoral fellowship. Funding is also available at the undergraduate level. Other forms of
financial support include research grants, symposia and conference grants, as well as publication
grants in the form
Dr. Shyam S. Manraj (Healthcare Consultant) gave an update on biomaterials, drug delivery,
nanomedicine, and biosensors in Mauritius. He spoke about a symposium in Mauritius entitled
Research for Health which will occur in Mauritius in March of 2009. Many issues in Mauritius
are with non-communicable diseases such as cardio-vascular, diabetes, and cancer. Considering
the state of these diseases he discussed the immense potential for the use of biomaterials in
therapeutics and diagnostics within the Mauritian and African communities. These included
glucometers, real-time PCR, mass spectrometry, digital mammography, targeted cancer therapy,
and drug-eluting stents.
A. Dookun-Saumtally (Mauritius Sugar Industry Research Institute) spoke on the present and
future technologies in sugar cane research. The sugar industry is supported by a strong R&D
program as sugar cane covers 37% of the island’s total area. The institute aims to promote
research and investigation as it applies to crop improvement, protection, diversification, and
mechanization. New technologies give the region access to precision agriculture, soil
management, water and nutrient control, as well as pest and disease management. Also
discussed were the roles of biotechnology, technology transfer, and economics of the sugar cane
industry.
H. Ramsurrun (Rajiv Gandhi Science Centre) shared his vision for public engagement in
nanotechnology in Mauritius. The goal of this centre is to promote scientific literacy and
popularize the field of nanotechnology for the socioeconomic development of the country. They
intend to organize an international conference on nanotechnology in an attempt to engage the
public and close the gap between high tech research and the general public. Mauritius is striving
to be a leader in world class nanotechnology as it applies to energy, agriculture, health,
cosmetics, and water supply.
Mr. Anad Priyay Neewoor (Secretary of Foreign Affairs) defined the current bilateral
cooperation between Mauritius and the USA. Each country shares a vision of entrepreneurship
and those attitudes must be leveraged through collaboration in science and technology. The US
is currently supporting Mauritius in oceanography research and in the past as collaborated with
the University of Maryland for the development of a medical school in Mauritius. However,
more can be done to promote research collaborations between Africa and the United States.
10
Kreshna Gopal (Board of Investment) gave an overview of the Healthcare and Life Sciences
Cluster in Mauritius. Their goal is to facilitate businesses who want to develop in Mauritius.
The board provides guidance on company location, what facilities should be available, and helps
them attain the licenses and clearances necessary to do business in Mauritius. The number of
health-care professionals is on the rise in Mauritius so alliances must be built between
investment companies, research institutions and academia. It is a goal to develop regional
laboratories and institutions so that Mauritius can take an active leadership role in scientific
research.
NATEC Medical Ltd (Medical Device Manufacturing) spoke on their experience with the
challenges, needs, and opportunities associated with doing business as a medical device company
in Mauritius. Challenges include human resources, supply of raw materials, quality systems, and
fluctuations in currency. By keeping R&D local NATEC Medical Ltd has helped invest in
education and training in order to keep medical device manufacturing held to a global standard.

4. Future Plans and Planning
a. Education
Masters Course:
• Establish a masters-level course on Biomaterials as a centerpiece for a strong program in
biomaterials, leading in a first instance to a postgraduate certificate from the University of
Mauritius
• Compile example curriculum from participants and distil to a usable course syllabus that can
accommodate students from different disciplines
• The course will be modular in nature to suit students with different backgrounds (chemistry,
biology, engineering, medicine, etc.) and at different levels, undergraduate, graduate, and
continuing education
• Identify prerequisites or related preparations for students depending on background
o the first 10 lectures could be designated to make up for deficiencies in background
o some basic molecular biology or biochemistry classes could be required from
engineering/chemistry
o The beginning of the course should include basics in cell biology
• Modular approach, a common first module to get everyone to the same level, other modules may
cover nanotechnology, biosensors, regenerative medicine, and drug delivery
o Develop the modules in the three parts as covered in the conference. Teach the entire
module with an emphasis on biomaterials as they apply to:
ƒ Part 1: Regenerative Medicine
ƒ Part 2: Drug Delivery
ƒ Part 3: Nanotechnology/Biosensors
ƒ Part 4: Medical Devices, Imaging
o Exam/Quiz frequency is different in Mauritius than in the United States, they only have
exams at the very end of the semester but suggesting shorter quizzes, one after each
module instead of 1 large final exam would be most beneficial for student learning
o A final paper could be written on a topic of the student’s choosing in consultation with the
faculty teaching the course
o Students could present on specific research papers, this is helpful when the students focus
on 2 papers and place it in a broader context (by reading). They then are encouraged to
find links between the bench and the scientific conclusions. More advanced levels will
also critically comment on the papers from their perspective/background
o Notes on course – est. at 90 hrs, rationale– build capacity for hospitals setting up world
class labs, training, build student expertise, etc.
• Potential to use video conferencing so the faculty from overseas can help to teach
o Video facilities are available at University of Mauritius
o Also Skype is used quite frequently
o the 9-12 hour time difference between the US and Mauritius needs to be considered
o If lectures were to be given from the United States, then doing a 3 hour course once a
week could make sense, perhaps have each professor speak for 2 weeks at a time and
then switch to the next professor/topic.
12
o Much like Blackboard in the United States, the University of Mauritius has a system
called the Virtual Centre for Instructive and Learning Technologies where professors can
post their PowerPoint slides and students can access via password
o Handouts and reading material should be made available prior to the class so students can
review and/or print off material before the class
o Presenters from the US at the conference provide copies of their slides for use as a
template in preparing the course materials. These slides would be available only to
registered students for the course.
o How do international (USA, SA, France) faculty gain access – courtesy appointments or
all materials funneled through Dhanjay
Other Educational Goals:
• No such course exists in the Indian Ocean Region and Sub-Saharan Africa, need to look into such
courses in South Africa and find bridges with needs there – to expand the outreach of the
proposed course on biomaterials
• Prepare a pool of trained scientists in Mauritius to sustain industrial development in this area –
such as through the course plans, collaborative research plans (see below) and the masters degree
plans.
• Provide continued education for doctors, industry professionals, and government specialists, the
world of biomaterials for the region should be open not to just students at the University of
Mauritius, but also a wider range of students. May need approval from the Mauritian Medical
Association.
• Seek broader involvement by potential stakeholders: Mauritian Medical Association, Mauritian
Plastics/Polymers Society, etc.
13
b. Research Collaborations:
Research Projects –
• Identify and follow up on research collaborations among the faculty present (see listing below).
These would be one-on-one follow ups. A number of these interactions were discussed at the
meeting.
o There should be a “BIOMATERIALS” website as soon as possible to serve as the focal
point from the workshop, ongoing plans, course details and research opportunities. Links
to other options in the region can be included, such as the South African Biomaterials
Society, Dhanjay’s web site (www.uom.ac.mu/polymer), industries, etc.
Student Exchanges:
• Identify collaborative research projects and students from Mauritius or from other countries may
wish to come to host labs for extended stays (1 year is recommended) – funding would be from
Mauritius government fellowships or other sources to be identified.
• Funding under the OISE students from Mauritius on joint research – estimate of costs (per student
per year, $1,500/month plus travel = $20,000/student year), with goals of three students in year 1
and five students per year thereafter. Thus, $60,000 is needed in year 1 to initiate the program
and $100,000 each year thereafter.
• Funding from the NSF to support such exchanges. The NSF mentioned that they would consider
proposals coming from this Workshop. It is recommended that a portfolio of short proposals, one
from each US representative, be identified and packaged into a single USA-Mauritius
submission for NSF-Mauritius funding. The Mauritian Ministry of Education should be
encouraged to co-fund these proposals.
• Solicit help from the US embassy in Mauritius
• Seek internships for University of Mauritius students abroad to develop their knowledge and
experience in biomaterials research, development and applications.
• Top students from Mauritius should be selected initially to promote initial success for the program
of exchanges – masters level or PhD level
Specific Joint Research Projects Initiated from the Meeting – these are ideas generated in discussions at
the meeting. The details of each project will be worked out in the coming weeks by the participants
listed on the Table to see if they are viable to move forward.

Appendix E: Proposed Graduate Course in Biomaterials
CHEM 6088: BIOMATERIALS
UNIVERSITY OF MAURITIUS
Faculty of Science – Department of Chemistry
MODULE OUTLINE
Part 1: Basics in Biomaterials (45 hours)
The first section of this module will study the material properties of various metallic, ceramics, and
polymer components used within and in contact with the human body. Stress and strain
relationships for these biomaterials will be studied based upon standard mechanical engineering
fundamentals. In addition, the peculiar aspects of biological and physiological materials will be
studied with respect to their differences from non-living materials. The material properties of
biological and physiological components will also be studied based upon standard material science
protocol. The particular application of each of these materials within a living system will be studied
as well as the role of these applications in the manufacturing processes for these materials.
Part 2: Application of Biomaterials in Regenerative Medicine (15 hours)
The second section of this module will study the system strategies for the design, synthesis,
characterization and functional properties of biomaterials for tissue engineering/regenerative
medicine. Fundamental issues related to the utility of biomaterials including biocompatibility,
stability, interfaces, and fate in the body will be addressed. This module will also include the clinical
applications for biomaterials and new directions in design and synthesis to enhance biocompatibility
and direct stem cell fate. This module will also address testing methods, regulatory and ethical
issues, and emerging research directions.
Part 3: Drug Delivery Concepts and System Design (15 hours)
The third section of this module will include an introduction to biopharmaceutics as well as drug
delivery system design (biomaterials) with attention to the pharmodynamics, and
pharmokinetics. This module will discuss classical drug delivery systems (i.e. transdermal
delivery systems) and novel drug delivery systems (i.e. dendrimer delivery systems) currently
under development. The majority of the examples will focused on the treatment of cancer.
Part 4: Application of Biomaterials – Biosensors (15 hours)
61
The fourth section of this module will introduce the concept of biosensors from the standpoint of
biochemical interactions that are used to detect and/or quantify biological molecules as well as the
basic systems used for detection.
Module Goals:
• Understand the fundamentals of biomaterials structure-function relationships pertaining to
material functions and to cell and tissue environments
• Understand biomaterial, cell and bioreactor challenges in tissue engineering – from both
engineering and biological constraints
• Understand the fundamentals of drug delivery systems from a polymer science, engineering and
biological constraints
