Optical Spectroscopy for Biomedical Diagnosis

In the last few decades there has been a remarkable growth in the development of optical spectroscopic techniques for in situ, sensitive, minimally invasive diagnosis. In this article we provide an overview of the field and highlight some representative applications. Special emphasis has been placed on the use of optical spectroscopic techniques for non-invasive diagnosis of cancer where a significant amount of work has been carried out in the country.
