Raman spectroscopy in the analysis of food and pharmaceutical nanomaterials

Raman scattering is an inelastic phenomenon. Although its cross section is very small,recent advances in electronics, lasers, optics, and nanotechnology have made Raman spectroscopy suitable in many areas of application. The present article reviews the applications of Raman spectroscopy in food and drug analysis and inspection, including those associated with nanomaterials. Brief overviews of b…
