Abstract

Electrical conduction through a DNA molecule is significantly dependent on the mode of connection with metallic leads (see picture). A variation of conductance of seven orders of magnitude is found with the Landauer formulation in an (AT)₁₂ DNA molecule. The DNA molecule behaves as a semiconductor when bases are connected to the gold lead, whereas it is insulating when nucleic acids are connected.
