The observed Raman signals can be ascribed simultaneously to Surface Enhanced Raman Scattering (SERS) cross section alongside the reduction of fluorescence due to the Nanomaterial Surface Energy Transfer (NSET) phenomenon .To benefit from these two effects we produced two patterns: colloidal state and self-assembled monolayer(SAM) substrate of nanoparticles. The two patterns demonstrated well-consistent and confirming results. M3 ER -
