Electrochemical oxidation of guanine: electrode reaction mechanism and tailoring carbon electrode surfaces to switch between adsorptive and diffusional responses.

Abstract:

The electrochemical oxidation of guanine is studied in aqueous media at various carbon electrodes. Specifically edge plane pyrolytic graphite (EPPG), basal plane pyrolytic graphite (BPPG), and highly ordered pyrolytic graphite (HOPG) were used, and the voltammetry was found to vary significantly. In all cases, signals characteristic of adsorbed guanine were seen and the total charge passed varied from surface to surface in the order roughened BPPG > EPPG > BPPG > HOPG. It is of note ...
