| 中文摘要 | we investigated the binding characteristics of double-stranded dna to self-assembled monolayers (sams) containing viologen groups formed on the surface of gold electrodes via au-s bonds. the positive charged and hydrophobic surfaces of the viologen sams modified gold electrodes are suitable to bind strongly dth dna, whose interactions to solution dna and adsorbed dna both lead to positive shifts (22.5 mv and 65 mv, respectively) in the first redox potential ci viologen centers, indicating that the main interaction is from a hydrophobic interaction. meanwhile, the binding of dna strongly affects the kinetics of electron transfer of the viologen group so that the separation of anodic and cathodic peak potentials becomes larger and the heterogeneous electron transfer constant becomes smaller. |
