Patent number: 7875197Abstract: 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.Type: GrantFiled: August 6, 2008Date of Patent: January 25, 2011Assignee: President and Fellows of Harvard CollegeInventors: George M. Whitesides, Younan Xia, James L. Wilbur, Rebecca J. Jackman, Enoch Kim, Mara G. Prentiss, Milan Mrksich, Amit Kumar, Christopher B. Gorman, Hans Biebuyck, Karl K. Berggren
