  • Method of nanopatterning by forming cracks in a coated polymer substrate
    Patent number: 7232686
    Abstract: Nanopatterned devices are easily fabricated, over large surface areas when desired, by forming a multilayer article of deformable substrate, brittle layer, and coating layer, and deforming the multilayer film such that a plurality of cracks are formed therein. The cracks have different physicochemical properties than the non-cracked coating layer, and advantageously serve as attachment points for culturing microorganisms.
    Type: Grant
    Filed: June 24, 2003
    Date of Patent: June 19, 2007
    Assignee: The Regents of the University of Michigan
    Inventors: Shuichi Takayama, Xiaoyue Zhu, Joong Hwan Bahng, Elizabeth Ho Liu, Jeongsup Shim
