We report on a reversible polymerization of ambient carbonaceous deposits on the surface of gold microstrips by means of a voltage-biased atomic force microscope tip in air. This approach is found capable of controlled writing, erasing, and rewriting of carbon-rich deposits with sizes in nanometer regime. Physical mechanism for this reversible patterning is proposed to be the current-induced electrochemical process. In addition, we introduce a novel nanomachining technique based on an electric field enhanced cutting process.
