Electrochemical Reactions of Organic Materials on Diamond Electrodes
The electrochemistry of diamond has gained much importance due to its stability, low background current and wide potential window in aqueous electrolytes. We have used high quality diamond films both from fundamental and applied viewpoints. The detection of biologically important compounds such as dopamine was found to be possible at very low concentrations even in the presence of ascorbic acid, which interferes frequently in biological systems. Similarly, oxidation of nicotinamide dinucleotide (NADH) was observed, with a well defined cyclic voltammogram even in the micromolar range. The electrochemical reduction of C60 at diamond electrode was studied in acetonitrile-toluene mixture, and six reduction peaks were observed at room temperature.
