Application of surface-enhanced vibrational spectroscopic techniques in analytical chemistry, the role of substrate surface morphology: case study
Original language description
Films and monolayers of organic compounds on several metal surfaces are widely studied and analyzed by surface enhanced Raman scattering (SERS) and surface enhanced infrared absorption (SEIRA) spectroscopy considering significantly increased sensitivityof these techniques with respect to their normal (non-enhanced) counterparts. Both SERS and SEIRA found their EM mechanism origin in a light interaction with nanoparticles/nanostructures. SERS is observed primarily for analytes adsorbed onto the surfaceof coinage (Au, Ag, and Cu) metals, because they match very well the (plasmon) resonance condition and are able to give efficient SERS effect in visible and/or near-infrared range. The aim of this work is: (i) development of appropriate combined electrochemical preparation procedures of copper substrates using the cathodic reduction from electrochemical baths with oxidation-reduction cycles treatment and (ii) elucidation of detailed structural architecture of the model analyte (4 aminobe
