Deep non-invasive Raman spectroscopy of living tissue and powders

Abstract

This tutorial review examines emerging Raman spectroscopy techniques for deep non-invasive probing of diffusely scattering media such as living tissue and powders. As generic analytical tools, the methods pave the way for a range of new applications for Raman spectroscopy, including disease diagnosis, non-invasive probing of pharmaceutical products in quality control and security screening.
