Abstract
We have studied the electrical conductivity of DNA film using nanogap electrodes. Current-voltage measurements and alternating current measurements were performed for analysis of conductivity. The electrical conductivity of the DNA films of poly(dG)·poly(dC) are found to depend strongly on the humidity. The resistance of poly(dG)·poly(dC) decreases dramatically with increasing relative humidity. The contact resistance between DNA film and Au electrodes is also examined by the conventional four-probe technique.
