Molecular lithography with DNA nanostructures.

A method of making molecular lithographs and molecular lithographs prepared by a bottom-up synthesis of nanopatterns having discrimination at the level of several nanometers. Molecules such as DNA may be configured to pattern useful configurations. Lithographs enabling the reproduction of the patterns may be prepared according to the claimed method. Chemically bound molecules provide a mask for electrical connections that may be prepared by subsequent known processes from the lithograph.
