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.
