Abstract

Recently, two groups used electrostatic force microscopy to probe the electrostatic polarization of DNA. As such, the results were consistent with the findings that DNA is insulating. However, the electrostatic force-microscopy technique probes conductivity in the limit of weak bias potentials, so it does not rule out a transition to moderately large conductivity above a bias threshold of several volts. The presented experiments showed that insulating behavior extends to bias potentials as high as 20 V.
