Abstract

A fast method of creating nanostructures comprising the steps of forming one or more electrically-charged regions (5) of predetermined shape on a surface (1) of a first material, by contacting the regions with a stamp for transferring electric charge, and providing electrically charged nanoparticles (7) of a second material, and permitting the particles to flow in the vicinity of the regions, to be deposited on the regions.
