The institute is equipped with cutting edge instrumentation, from conventional confocal fluorescence microscope to Raman and Infrared imaging systems (http://www.dit.ie/focas/facilities/). In recent years, research in Focas has greatly contributed to a better understanding of the potential of vibrational spectroscopy for biological applications. The wide range of application covers studies going for single cells to tissue analysis. On one hand, Infrared spectroscopy is particularly suitable for the analysis of large tissue area and has been proven suitable for diagnostic applications and the specific identification of pathological samples in the case of cervical and lung. On the other hand, the high spatial resolution when working with Raman spectroscopy has allowed to access information at the subcellular but also sub-nuclear level. The mapping of single cells in vitro can deliver crucial information regarding cell-drug interaction interaction but can also help to the localization and tracking of nano-particles inside the cells without requiring any labelling. Coupled with the development of applications of the experimental techniques, multivariate analysis and data mining tools are being developed and validated to improve and optimise their sensitivity for probing sub-cellular components and processes at a molecular level. Title: The role and function of water in biology: a spectroscopic study In the modern day field of biology, dominated over the past 50years by the emergence of genomics, proteomics and metabolomics, water has been largely considered to a position of inert or passive background. However, it has become increasingly clear over the past 2 decades or so that water is not simply “life’s solvent” but is a substance that actively engages and interacts with biomolecules in complex, subtle, and essential ways. This project aims to apply a range of physicochemical imaging modalities, based on molecularly specific spectroscopic techniques, to map out and explore dynamic water structure within biological systems, and the active role it takes in cellular function and dysfunction, underlying disease, therapeutics and resistance. Water can have up to 18 different crystalline phases, and thus the project explore the fundamental properties and spectroscopic signatures of water structures. It will extend to the study of water structures at biological interfaces, both biomolecular and at membrane interfaces. It will explore the use of spectroscopy to probe the structure internally in cells, and monitor the changes in structure as a response to radiation, chemotherapeutic agents and other external influences.
