✦ Synopsis

Electrochemical investigation of CuTMAP and its interaction with DNA at a Hg electrode is reported for the first time. The reduction of CuTMAP under our experimental conditions involves reduction of 2e of Cu 2/ and 2e of TMAP. Reaction of DNA with CuTMAP forms an electrochemically nonactive complex, which results in a decrease in the CuTMAP equilibrium concentration and its reduction current. The decrease in peak current is proportional to DNA concentration and can be used to estimate DNA concentration.

An electrochemical study of the interactions of hemin with DNA on a hanging mercury drop electrode (in ammonia buffer solution) is described. Adding DNA in hemin solution resulted in decrease of both the hemin reduction peak and the catalytic hydrogen wave. Electrochemically nonactive hemin-DNA comp

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 anthr

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
