A new sensor for determination of Ag + ion (Ag + ) by surface-enhanced Raman scattering (SERS) is reported. Gold nanoparticles (AuNPs) and 4-aminodiphenyl disulfide (APDS) were chosen as the SERS substrate and probe molecule, respectively. With the addition of Ag + , three new peaks (1141, 1392, and...
