Graphene oxide/(Au/Ag) hybrid materials, which have significant value in pollutant detection, chemical sensing and cancer diagnosis, have received considerable attention for recent years because of their excellent surface-enhanced Raman scattering (SERS) effects. In this review, the synthesis methods and SERS effects of three kind of graphene oxide/(Au/Ag) hybrid materials (graphene oxide decorated with Au/Ag nanoparticles, graphene oxide encapsulated Au/Ag nanoparticles, graphene oxide coated on Au/Ag nanoparticles films) have been summarized in detail. SERS studies show that by combining with the respective advantages of Au/Ag nanoparticles and graphene oxide on the research and application of SERS, graphene oxide/(Au/Ag) hybrid materials have more excellent SERS effect than pure Au/Ag nanoparticles. Graphene oxide plays an important role in chemical enhancement, molecule enrichment, surface passivation and fluorescence quencher. Graphene oxide/(Au/Ag) hybrid materials have broad application prospects in SERS.
