Laser Raman spectroscopy: Some clinical applications

Recent advances in lasers, multichannel detectors and PC-based spectroscopi c instrumentation have made Raman spectroscopy an invaluable tool for chara cterization of clinical samples like tissue, body fluids and cytological sm ears. Efforts are being made at present to develop Raman spectroscopy techn iques for optical pathology, early detection of neoplasia, analysis of body fluids, optical imaging, spectral markers for identifying clinical conditi ons, etc. Some of the results which will lead to such applications are pres ented in this paper.
