Surface-Enhanced Raman Scattering of Adenine, Adenosine and ATP Molecules

摘要: The surface-enhanced Raman scattering (SERS) of adenine, adenosine and ATP molecules adsorbed on Ag electrodes are studied. Our results indicate that they all have similar SERS spectra, same voltage dependence concentration dependence. All these can be understood by considering the through adenine rings with end-on or flat-on orientations. It is found signals for increase steadily consecutive oxidation-reduction cycles between -0.3 → 0.2 Vsce. This use adatom model SERS.
