The demand of continuous detection technology for gas phase trace explosives (GPTE) in explosion-proof stability maintenance, public security, explosive security storage and other occasions is summarized. By studying the development status and research trends of surface enhanced Raman scattering (SERS) detection technology to detect GPTE, an application of a double enhanced Raman scattering (DERS) substrate consisted of a novel 1D composite silver grating and gold nanospheres colloids in the GPTE detection was presented. The detection sensitivity of 2,4,6-trinitrotoluene (TNT) and cyclotrimethyltrinitroamine (RDX) was 10-11 mol/L. Combining with microfluidic technology, it can realize in-situ and continuous GPTE detection. This DERS substrate has a significant reference for the application of SERS detection technology in food safety, health care and environmental monitoring, et al.
