    Arrays of polypyrrole (Ppy) dots (80-180 nm diameter) have been prepared in a highly parallel fashion. This process is achieved by templating Ppy growth on a 2D surface micelle array, initially formed by the Langmuir-Blodgett (LB) technique. Ppy growth on self-assembled (SA)-based surface micelles produces more complex structures, due to simultaneous reorganization of the SA micelles. These results demonstrate that template growth of conducting polymers can be used to fabricate configurations that are otherwise inaccessible.
