| Raman spectroscopy during the last decades is gaining more and more attention in analytical applications and can provide chemical fingerprints of cells, tissues and biofluids. In contrast to established analytical techniques, this vibrational spectroscopy provides label-free, non-destructive, chemically selective and spatially resolved analysis. Actually, the high chemical specificity merged with the ability to use advanced optical technologies in the visible or near-infrared spectral range have recently led to an increase in medical diagnostic applications of Raman spectroscopy. Several experimental setups can be optimized, from confocal microscopes for acquisition of three-dimensional spectral information up to optical fiber-based devices for direct use in clinical diagnostics. Since Raman spectroscopy is characterized by weak signal problems, new strategies, mainly based on nanotechnological solutions, have been developed exploiting non-linear optics and localized plasmonic effects aimed to enhance the Raman scattering efficiency, increasing the acquisition speed and accuracy of diagnosis. This symposium will outline the applications of the various Raman spectroscopy based techniques in the broad area of Nanomedicine, ranging from the use of nanomaterials, drug delivery strategies, medical diagnostics and therapeutics. |
