Abstract
The electrochemical oxidation of DNA and bases at a glassy carbon electrode were investigated using cyclic and square-wave voltammetry analysis. The predicted oxidative potentials for DNA and bases using DFT method (B3LYP) are in agreement with the experimental ones.The DNA oxidation ascribes to N-protonated guanine and adenine. The calculated oxidative peaks indicate that the initial potential of DNA oxidation is around 0.432V for N-protonated guanine and 0.368V (vs.hydrogen standard electrode) at pH 7.00, and DNA as well as bases in acidity solution are more stable than those in alkalescent solution.
