Applying the Au/PATP/Au nanoparticles sandwich structUre as the model system, a semi-quantitative study on the SERS intensity with the size of Au nanoparticles has been performed. It shows that the SERS intensity incr...
Gold nanoparticles were assembled on gold substrates with the self-assembled monolayer(SAM) of p-minothiophenol(PATP). AFM measurements disclose that gold nanoparticles are scattered over the surface of the substrate ...
