              This study tested the possibility of using resonance Raman spectroscopy to detect cocaine in oral fluid without pretreating samples.
Abstract
              Detecting and quantifying cocaine in oral fluid is important for practical forensics. Up to date, mainly destructive methods or biochemical tests have been used; however, spectroscopic methods were only applied to pretreated samples. The current study found that ultraviolet resonance Raman spectroscopy with 239-nm excitation can detect cocaine in oral fluid at 10 ìg/mL level. Further method development will be needed for reaching the practically useful levels of cocaine detection. (publisher abstract modified)
