Abstract

We will report a novel technique to make biocompatible, conductive micropatterns on insulating substrates such as glass or polyimide by controlling the lateral growth rate of polypyrrole (PPy) upon electropolymerization at microelectrodes formed on the substrates. We found that pre-modification of the substrate surface with self-assembled monolayer (SAM) of alkylsilane or heparin induces anisotropic (more than 10 times faster) lateral growth of PPy films along the substrate surface. This controllable anisotropic growth of conducting polymers has enabled the following studies, including the formation of hybrid micropatterns of cells and conducting polymers.
