Modification of a SERS-active Ag surface to promote adsorption of charged analytes: effect of Cu2+ ions
This work studies the hindirochakkahaniya.com impact of the electrostatic interaction between analyte molecules and silver nanoparticles (Ag NPs) on the intensity of surface-enhanced Raman scattering (SERS).For this, we fabricated nanostructured plasmonic films by immobilization of Ag NPs on glass plates and functionalized them by a set of differen
