摘要
The Ni 2+/poly(o-aminophenol)electropolymerization was carried out by a continuous cyclic voltammetric scanning at a carbon paste electrode in a mixture of 0.02 mol/L o-aminophenol,0.3 mol/L NiSO_ 4 and 0.6 mol/L HClO_ 4.dsDNA was linked to the conducting polymer via three-dimensional structure of polymer film and electrostatic attraction between the negatively charged phosphate backbone of DNA and Ni 2+ ion.The results were testified by the electrochemical methods by using Co(phen)2+_3 as an electrochemica...
