Abstract :
Electrical transport through DNA molecules is of fundamental interest and could have an impact on nanoscale device applications such as molecular electronics. A few interesting transport data have been reported in the last couple of years, but the transport mechanism through DNA molecules is less understood. We report direct measurements of electrical conduction through 60 base pairs of poly(G)-poly(C) DNA molecules (20.7 nm long) connected in between two metal electrodes with nanometer spacing.
