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

Patent number: 7816665Abstract: A negative differential resistance (NDR) device, and methods of making and using the NDR device. The NDR device includes a substrate comprising a conductor material or a semi-conductor material and a self-assembled monolayer (SAM) that includes a first electroactive moiety and a spacer moiety disposed on the substrate that defines a barrier between the electroactive moiety and the substrate, wherein the NDR device exhibits negative differential resistance in the presence of a varying applied voltage. Also provided are NDR in multilayers in which the peak to valley ratio of the NDR response can be controlled by the number of layers; modulation of NDR using binding groups to one of the electrical contacts or to the electroactive moiety itself; and NDR devices that display multiple peaks in the current-voltage curve that contain electroactive moieties that have multiple low potential electrochemical oxidations and/or reductions.Type: GrantFiled: February 27, 2003Date of Patent: October 19, 2010Assignee: North Carolina State UniversityInventors: Christopher B.
