Raman spectroscopy techniques have been widely used in field of on site fast detection owing to their unique advantages such as simplicity,rapidness,nondestruction,abundant fingerprint information and low aqueous interference,etc.Especially,surface enhanced Raman spectroscopy(SERS) technique has significantly improved the sensitivity for on site detection,and further complemented the ultrasensitive application.Herewith,a comprehensive overview on applications of Raman spectroscopy techniques in on site fast detection was presented.This review was divided into two parts,ie.direct and indirect detections,including typical Raman sensing strategies for food security,criminal investigation,biomedicine management,and environmental regulation.Finally,the tendency for future development of Raman spectroscopy techniques in on site fast detection was proposed.
