Local and bulk deposition of gold particles was accomplished by the spontaneous reaction between chem. reduced polyaniline (PAN) thin films and AuCl4-. PAN layers were deposited on glass, ITO, and glassy C (GC) by the Langmuir-Blodgett method and spin-coating. Characterization of the PAN films was carried out by microscopy, UV-vis spectroscopy, and electrochem. The nature of the Au deposit was greatly affected by the thickness of the PAN. Scanning electrochem. microscopy was used as a means of locally depositing Au nanoparticles on an unbiased PAN film by anodically dissolving a Au microelectrode. This represents a generic approach whereby a variety of metal micro- and nanoparticles can be locally deposited on insulating supports. [on SciFinder(R)]
