A new method for fabricating carbon nanotube-conducting polymer (CNT-CP) composite single nanowires is reported. The method developed is highly efficient, reliable, and economical because it obviates the time consuming process of template fabrication and the post-synthesis task of positioning nanowires. Single nanowires with diameters of 50-500 nm are fabricated between electrodes, self-templated by dielectrophoresis and electropolymerization. Fabrication of an individually addressed nanowire array with cantilever electrodes on a microchip is demonstrated.
