TL;DR: In this paper, voltammetric methods were used to probe the interaction (electrostatic or intercalative) of metal complexes, ML 3 3+/2+, with calf thymus DNA.
Abstract: Voltammetric methods were used to probe the interaction (electrostatic or intercalative) of metal complexes, ML 3 3+/2+ , with calf thymus DNA. Binding constants (K n+ ) and binding site sizes (s) were determined from voltammetric data. The exact magnitude for the parameters depends on whether the ML 3 3+/2+ /DNA reaction is assumed to be static (S) or mobile (M) within the characteristic time of a voltammetric experiment
