• DNA has recently attracted much attention in view of its possible applications to nano-devices. Despite extensive efforts, however, the experimental results of the electrical conductivity of dry DNA are still rather controversial. In this report, we indicate that a key issue to interpret the experimental results could be the role of counter metal cations, which are expected to alter the electronic properties of pure DNA. In particular, although metallic cations are passivated by hydration, some divalent anhydrous ones originating by drying processes may exist and act as acceptors, doping holes in the host (DNA) HOMO band with the spin distribution localized around the cation. Some consequences relevant to the transport properties are also discussed. The analysis of the various electronic structures presented here will provide a clue for further detailed insights into the transport properties and related mechanisms in DNA chains.
