Open AccessSelf-assembly of gold nanoparticles to silver microspheres as highly efficient 3D SERS substrates
Herein we report a simple, one-pot, surfactant-free synthesis of 3D Ag microspheres (AgMSs) in aqueous phase at room temperature. The 3D AgMSs act as supports to fix the gold nanoparticles (GNPs) in 3D space v...
