Abstract：The noble metallic nanoparticles/graphene composite substrates have attracted more attentions because they can be served as high sensitive,good stable and biocompatible substrates for Raman spectroscopy analysis technology.Based on the electromagnetic and chemical mechanisms,the mechanism of surface-enhanced Raman scattering(SERS)for the noble metallic nanoparticles/graphene composite substrates is discussed systematically. Then the preparation methods and performances of graphene and noble metallic nanoparticles are summarized respectively,and the processes of the grapheme prepared by the chemical vapor deposition method and noble metallic nanoparticles prepared by the physical method are introduced in detail.On this basis,the domestic and abroad research progresses of SERS for different noble metallic nanoparticles/graphene composite substrates are synthetically expounded and analyzed.The noble metallic nanoparticles are composite system with Ag,Au and Pt,and the applications and developments of SERS technique for noble metallic nanoparticles/graphene composite substrates in various fields are prospected.
