Study on the Electric Conductivity of Ag-Doped DNA in Transverse Direction.
In this article, we reported a novel experiment results on Ag-doped DNA conductor in transverse direction. I-V characteristics were measured and the relative conductances were calculated for different silver ions concentrations. With the increase of the concentration of silver ions, the conductive ability of DNA risen rapidly, the relative conductance of DNA enhanced about three magnitudes and reached a stable value when Ag(+) concentration was up to 0.005 mM. In addition, Raman spectra were carried out to analyse and confirm conduction mechanism.
