Electrostatic binding between metal complex probes such as ferrocyanide, [Fe(CN)₆]^4-, and Polyamidoamine (PAMAM) dendrimers were studied using cyclic voltammetry (CV). Generations one through five were investigated for electrostatic binding at various pH levels and ionic strengths. The CV peak currents observed drop as binding occurs. This is accompanied by a net positive shift in redox potential. Binding constants were obtained through non-linear regression analysis. Stronger binding is found for higher generations and at lower pH values.
