Characterization of Multilayer-enhanced Surface-enhanced Raman Scattering (SERS) Substrates and Their Potential for SERS Nanoimaging

Abstract  Multilayer gold surface-enhanced Raman scattering (SERS) substrates, which consist of continuous gold films that are separated by self-assembled monolayers (SAMs) and cast over 430-nm diameter silica nanospheres on a glass slid
