Electrochemical Oxidation of Adenine: A Mixed Adsorption and Diffusion Response on an Edge-Plane Pyrolytic Graphite Electrode

Electrochemical Oxidation of Adenine: A Mixed Adsorption and Diffusion Response on an Edge-Plane Pyrolytic Graphite Electrode

Understanding the oxidation of the purines adenine and guanine is primary to improving electrochemical methods of DNA detection and analysis. Adenine in the solution phase is reported to undergo a complex electrochemical oxidation mechanism that is overall a -6H+, -6e- process, involving irreversibl...
