Abstract The surface-enhanced Raman scattering (SERS) effect was first observed on silver electrodes roughened by oxidation reduction cycles. The advantages of the latter with respect to the electrodes in an electrochemical cell are due to the large adsorption capability and the simplicity in the preparation of the SERS-active substrate. In addition, different SERS-active substrates and metal colloidal suspensions have been successfully employed. Silver colloidal nanoparticles are probably the most studied and a variety of procedures have been developed to produce monodispersed nanoparticles characterized by relatively small size variations. In this work, highly efficient and large-scale synthesis of silver nanostructures for the SERS-substrate was produced by electrolysis using sodium sulfate as an effective electrolyte. The silver nanostructures obtained were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD). The SERS spectra for different analytes in the silver nanostructures substrate were investigated.
