✦ Synopsis

The electrochemical behavior of the interaction of 9,10-anthraquinone with DNA on a hanging mercury drop electrode has been studied. In acidic and neutral media, nonelectroactive complexes are formed when anthraquinone interacts with DNA, which results in the decrease of redox peak currents of anthraquinone, but in alkaline media, anthraquinone shows significant electrocatalytic activity in relation to DNA. Both the decrease of peak current and the increase of peak current can be used to determine DNA concentration. The results of sample determination by electrochemical method are consistent with those by UV spectroscopy.

The electrochemical behavior of DNA at a glassy carbon electrode modified by 9,10anthraquinone was studied. The cyclic voltammogram of 9,10-anthraquinone CME in 0.10 mol/liter B-R buffer of pH 5.7 exhibits a redox wave at Οͺ0.48 V (vs SCE). On the addition of DNA in solution, both reduction and oxida
