Nanoscale patterning using photochemistry

Shuqing Sun and Graham Leggett at the University of Sheffield1 have developed a photochemical technique that allows the fabrication of structures with dimensions as small as 20 nm. The researchers use a near-field scanning optical microscope coupled to an ultraviolet laser to selectively oxidize a strongly bound monolayer adsorbed on a gold surface.
