Improved methods of forming a patterned self-assembled monolayer on a surface and derivative articles are provided. According to one method, an elastomeric stamp is deformed during and/or prior to using the stamp to print a self-assembled molecular monolayer on a surface. According to another method, during monolayer printing the surface is contacted with a liquid that is immiscible with the molecular monolayer-forming species to effect controlled reactive spreading of the monolayer on the surface. Methods of printing self-assembled molecular monolayers on nonplanar surfaces and derivative articles are provided, as are methods of etching surfaces patterned with self-assembled monolayers, including methods of etching silicon. Optical elements including flexible diffraction gratings, mirrors, and lenses are provided, as are methods for forming optical devices and other articles using lithographic molding. A method for controlling the shape of a liquid on the surface of an article is provided, involving applying the liquid to a self-assembled monolayer on the surface, and controlling the electrical potential of the surface.

[ What is claimed is:] [1.] A method of etching an article having a surface, comprising:contacting a first, nonplanar portion of the surface with a stamp to transfer to the first, nonplanar portion a self-assembled monolayer of a molecular species in a first pattern, the self-assembled monolayer bei

[ What is claimed is:] [1.] A method of etching an article having a surface, comprising:contacting a first, nonplanar portion of the surface with a stamp to transfer to the first, nonplanar portion a self-assembled monolayer of a molecular species in a first pattern, the self-assembled monolayer being contiguous with an exposed portion of the surface in a second pattern; andcontacting the article with an etchant that reacts chemically with the article thereby degrading a portion of the article in a pattern dictated by the pattern of the self-assembled monolayer.
