Outline of Final Research Achievements

Raman spectroscopy is a promising technique to visualize molecular information of cells and tissues based on molecular vibrations. This is now widely applied to biomedical imaging and its molecular analysis. However, autofluorescence from specimens limits the sensitivity of Raman spectroscopic analysis due to the autofluorescence spectrum appears at the same wavelength of the Raman spectrum and works as a strong background. In this study, we developed a Raman spectroscopy system with an autofluroescence elimination system based on the excitation wavelength dependency of the Raman scattering and autofluroescence.
