This paper investigates the comparison of glassy carbon to that of thin carbon films as electrode substrates. It is observed that the modification of the carbon surfaces, via the electrochemical reduction of aryl diazonium salts to the surface, occurs on both substrates in a similar fashion. Subsequent modification of the substrates with the peptide Gly-Gly-His attached to the bound layer, shows that...
In this work an oxidation reduction cycle (ORC) technique for fabricating polycrystalline gold foils as effective SERS substrates was systematically optimised. The potential of two other electrochemical techniques, (1) a potential step sequence (ORC-step) and (2) a one step electrochemical method which has been developed for fabrication of nano-porous gold films (NPGF) was demonstrated as an alternative...
