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.
