Applications of surface enhanced Raman spectroscopy in the detection of new psychoactive substances
Surface enhanced Raman spectroscopy(SERS)has highly sensitive adsorption enhancement effect and provides stronger Raman signals,identification of analytes can be achieved through the ob-served unique molecular fingerprint information.It is found that each kind of the new psychoactive sub-stances(NPS)have corresponding characteristic Raman signals.This article summarizes the SERS ap-plications for the detection of NPS including synthetic cannabinoids,synthetic cathinones,pipera-zines,tryptamines,ketamine&phencyclidine-type substances,fentanyls.This method has the advan-tages of high sensitivity,simple sample processing and fast detection.Hence,these Raman signals can provide scientific evidences for the identification of NPS.This article reviews the application progress of SERS in the detection of each kind of NPS in recent years,which provides a reference for the screening of NPS.
