The effect of DNA on the electrochemical behaviors of polyaniline was studied by cyclic voltammogram method. The presence of double-stranded DNA (dsDNA) did not influence the electropolymerization process of aniline monomers. dsDNA could not serve as an efficient dopant during the electropolymerization process of aniline monomers. There were no obvious changes of the electrochemical behaviors of polyaniline in the presence of dsDNA or not during the polymerization process. However, the anodic peak and cathodic peak current of the polyaniline film electrode gradually decreased with the increasing amount of dsDNA in electrolyte solution.
