CT-DNA were electrochemically immobilized on the surfaces of both nano-gold modified glassy carbon electrode and bare glassy carbon electrode. The cyclic voltammetrie behavior of Co (phen)₃³⁺ adsorbed on the immobilized DNA was studied. Increase in the peak current of Co (phen)₃³⁺ redox reaction was obtained on nano-gold modified glassy carbon electrode. The result suggests that more DNA molecules were immobilized on this electrode and nano-gold modification can enhance the heterogeneous electron transfer rate constant of the Co (phen)₃³⁺.
