Electrostatically Driven Dip-Pen Nanolithography of Conducting Polymers

Abstract

Nanoscale conducting polymer patterns have been fabricated on modified semiconductor substrates using dip-pen nanolithography (DPN). Electrostatic interactions between water-soluble ink materials and charged substrates are the driving force for the generation of stable DPN patterns. The conducting polymers have been characterized by lateral force microscopy (see Figure) and electrochemical methods.
