Biomedical Spectroscopy is the output of the intensive discussions of the authors and the medical professionals of Kasturba Medical College, Manipal University. The ?Centre for Laser Spectroscopy?, a centre for developing biomedical applications of laser spectroscopic methods, was established at Manipal University in 1997. The scientists of the Centre, together with the physicians, surgeons, and pathologists of the KMC, initiated a number of research programs in this area. The main aim of the Centre was to develop spectroscopic methods for early detection, screening, monitoring therapy and identification of disease markers, with special emphasis on various cancers, so that these techniques can be applied for routine healthcare applications. Outcome of these research activities are covered in the book. A common platform of information can provide a more open communication enabling faster and better evolution of the spectroscopic methods for biomedical applications. An attempt has been made to meet the needs of academicians and healthcare professional qualitatively, rather than theoretically. The purpose was not only to provide a common language for both of them to interact, but also to serve as a starting point for students and researchers who may like to embark in the rapidly advancing field of Biomedical Spectroscopy and applications of spectroscopic techniques in advanced medical technology. To facilitate this, we have tried to include a large number of references of current original research in the area of Biomedical Spectroscopy. This will enthuse many scientists and medical professionals to work together in this emerging field, so that medical technologies, which may not be affordable today, can be made routinely available in a highly cost effective manner.
