An electroless-microwave method is described here in order to synthesize electrically conductive gold
nano-wires on a DNA. The electrical characterization shows that the gold wires were formed on the
DNA. The nanowires were continuous, having low contact resistance, and exhibited the Ohmic
behavior of electrodes. These nanowires were found to be in a few micrometers long having the
diameter of 10-15 nm in solution and 20-30 nm in immobilized DNA with resistivity comparable to
pure metal. The nanowires fabricated here could be used as building blocks for functional
nanodevices, sensors, and optoelectronics.
