Elucidation of sorption model of riboflavin adsorbed on Ag, Au and Cu nanostructured surfaces
Original language description
Technique of Surface-enhanced Raman scattering (SERS) spectroscopy is a suitable analytical tool to study compounds adsorbed on Ag, Au or Cu surfaces. In-situ SERS spectroelectrochemistry allows investigation of surface intermediates in dependence on applied potential. Riboflavin, which interaction with surface has been studied in this work, is a compound of the vitamin B group. The investigation of riboflavin molecules orientation was carried out in special spectroelectrochemical cell using dispersiveRaman spectrometer with laser excitation at 785 nm. Aqueous solution (0.1 M KCl) of riboflavin (10-5 mol.L-1) was used as electrolyte and deposition bath simultaneously. In-situ SERS spectra of riboflavin adsorbed on the surfaces were recorded potentialvalue from +100 mV to -1100 mV with step 100 mV. From selection rules of SERS it is known that vibration modes perpendicular to the surface and located close to the surface are the most enhanced. We observed that bands intensities and the
