Reviewer for Journals: Tissue Engineering Outline of current postdoctoral research work My current postdoctoral research involves synthesis, characterization and use of polymeric biomaterials for regenerative medicine/tissue engineering applications. Oxidation responsive polymer micelles based on PPS-b-PDMA copolymer (by TAGT and RAFT). This is novel oxidation responsive micellar system which release the drug selectively under oxidative environment. Temperature and oxidation responsive thioketal shell cross-linked micelles based upon PEG113-b-PHEMA10-b-PNIPAAM136 for drug release response to oxidation and temperature. Use of biodegradable copolymers based on ethylene glycol (PEG), ε-caprolactone (CL) and carboxyl caprolactone (CPCL) for fabrication of electrospun cardiac patch for embryonic stem cell delivery to hypertrophic myocardium. Use of carboxylic group functional poly(ε-caprolactone) for vascular shape memory patch. My previous postdoctoral research involves synthesis, characterization of copolymers based on L, L-Lactide (LLA)/D, L-Lactide (DLLA) and ε-caprolactone (CL) and their use in fabrication of scaffolds for tissue engineering applications. Kinetics of solution and bulk copolymerization (with different feed ratio of LLA/DLLA and ε-caprolactone) and study of transesterification reactions by 13C NMR analysis. Copolymerization of different feed ratio of LLA/DLLA with ε-caprolactone using different concentration of catalyst. Microstructure analysis of prepared copolymers (by 13C NMR) and determination of reactivity ratio. Synthesis of high molecular weight copolymers of L,L-Lactide/D,L-Lactide with εcaprolactone and fabrication of nanofibres by electrospinning using varying parameters (such as solvent, concentration, flow rate, voltage, rotation speed, distance). My doctoral research deals synthesis and utilization of photo and thermo latent initiators for cationic polymerization. A detailed investigation on initiation activity of (xanthenyl, dibenzosuberenyl) phosphonium salts as thermo-latent initiator in cationic polymerization of epoxy monomers. The initiator activity was found to depend upon counter anions, phosphine moiety, ring structure and ring substituents. Benzophenone based allylic ammonium salt as one component additionfragmentation-agent (cationic initiator cum free radical source) in photopolymerization (λ > 290 nm) of cyclohexene oxide, vinyl ethers and n-vinyl carbazole. This is proved to be an efficient latent cationic initiator without use of radical source. Synthesis and use of allylic amide based phosphonium salts as new additionfragmentation-agent in conjugation with photo- and thermal radical initiators in free radical promoted cationic polymerization. They exhibit enhanced initiation efficiency as photo and thermo-latent initiator in presence of added radical initiators. Diselenides-aromatic nitriles based non-salt photosensitization system in cationic polymerization of NVC. A study on the cure behavior of bisphenol-A-type epoxides by differential scanning calorimerty (DSC) with phosphonium salts of xanthene and dibenzosuberene having different counter anions and ring substituents as thermo-latent initiators.
