Molecular wires connecting gold electrodes separated by a 100 μm insulating gap (see Figure) have been produced using a novel method for the microstructured deposition of polypyrrole lines on conducting substrates. The scanning electrochemical microscope used to deposit the lines is described and a microelectrochemical transitor produced using the technique presented.
