Abstract

Gold nanoparticles (GNPs) were successfully assembled on the surface of Ag microspheres (AgMSs) via the interaction between the carboxyl groups of GNPs and the silver atoms of AgMSs. The ensemble of AgMSs@GNPs with high SERS activity and sensitivity can be an idea 3D substrate choice for practical SERS detection applications. We believe that the simple self-assembly strategy may be extended to other metallic materials with great application potentials in SERS, catalysts, photoelectronic devices, etc.
