Binding of Δ , Λ [Ni(phen) 3] 2+ to calf thymus DNA was studied by circular dichroism and electrochemical methods. The selectivity of Δ isomer in binding to a right handed duplex of DNA was found. Binding constants and binding site sizes for Δ and Λ [Ni(phen) 3] 2+ with DNA were determined from voltammetric data.
