The description of nanolitography

Nanolitography is the process of development of certain nanostructures on the surface. This can be done by mechanical modification of the surface (scratching like process) or by local oxidation (when the conductive tip is biased). One can also perform manipulation of the DNA chains, nanotubes, single molecules. All mentioned techniques can be utilized in order to perform specific investigations in physical, chemical or biological field.
