Size-Dependent Interactions between Au Nanoparticles and DNA in Electrochemical Oxidation by Metal Complexes

Single-stranded oligonucleotides (ssDNA) containing guanine bases in their sequences were adsorbed onto gold nanoparticles (AuNPs) by electrostatic interaction. Cyclic voltammetry of Ru(bpy)3 2+ in the presence of the ssDNA-AuNP complex resulted in an enhanced anodic current due to the oxidation of...
