Electrosynthesized polypyrrole grows effectively at a hydrophobic substrate. Hydrophobic pretreatment of interdigitated microarray electrodes with silanization reagents prompts the lateral growth of polypyrrole film, resulting in the interconnection of arrays with a thin, uniform film. On the basis of this phenomenon, the micropatterning with polypyrrole can successfully be carried out by electropolymerization at a substrate with a silanized pattern.
