We report a new method to control both the nucleation and growth of polypyrrole (Ppy) and gold for the formation of nanometer-sized patterns using regioselectively immobilized oxidant and reductant as nucleation sites, respectively, for Ppy and gold. Poly(styrene-b-ethylene oxide) was used as a nanometer scale template. The height of Ppy and gold can be selectively grown only on PEO domains from 5 to 10 nm.
