New paper on medical creams

Congrats to Keith who co-authored work with colleagues at Chinese company Nycrist Pharmatech Limited and the Greater Bay Area Center for Drug Evaluation and Inspection of National Medical Products Administration, Shenzhen and the Dodd Walls Centre.  The paper describes us of Raman spectroscopy for the analysis of topical creams.  The power of Raman measurements is wonderfully depicted in Figure 3 of the paper.  Fig3 (a) is the optical image Fig3(b) the Raman image.  The API lights up with its strong Raman signals – no dyes required – just a bit of know how and light 🙂
