Abstract

DNA double helices comprising two neighbouring artificial imidazole–Ag(I)–imidazole base pairs incorporate the Ag(I) ions in a cooperative fashion. Isothermal titration calorimetry data confirm the theoretically predicted binding stoichiometry and indicate that Ag(I) binds with association constants >106 M−1 to the metal-free DNA duplex.
