Abstract
Surface-enhanced Raman scattering (SERS) is a technique mainly used for the detection of compounds such as organic pollutants, antibiotics, toxins, in very low concentrations; and for diagnostics and imaging in biomedical applications. Plasmonic nanoparticles (Au, Ag Cu, and their bimetallics) are well investigated in SERS because, under visible light irradiation, these nanoparticles pres…
