  • Cellular response to surface with nanoscale heterogeneous rigidity
    Patent number: 10550365
    Abstract: An elastomeric substrate comprises a surface with regions of heterogeneous rigidity, wherein the regions are formed by exposing the elastomeric substrate to an energy source to form the regions such that the regions include a rigidity pattern comprising spots.
    Type: Grant
    Filed: April 10, 2017
    Date of Patent: February 4, 2020
    Assignee: The Trustees of Columbia University in the City of New York
    Inventors: Manus J. P. Biggs, Ryan Cooper, Jinyu Liao, Teresa Anne Fazio, Carl Fredrik Oskar Dahlberg, Jeffrey William Kysar, Samuel Jonas Wind

  • Thin glassy polymer films including spherical nanoparticles
    Patent number: 8889766
    Abstract: A method of forming a solid-state polymer can include grafting a graft polymer to nanoparticles to provide grafted nanoparticles, and dispersing the grafted nanoparticles in a polymer matrix to provide a specified loading of the grafted nanoparticles within the polymer matrix to form a solid-state polymer. A solid-state polymer can include grafted nanoparticles comprising a polymer graft grafted to nanoparticles, and a polymer matrix, in which the grafted nanoparticles are dispersed to form a solid-state polymer, the dispersion configured to provide a specified loading of the grafted nanoparticles within the solid-state polymer.

  • Force, pressure, or stiffness measurement or calibration using graphene or other sheet membrane
    Patent number: 8418547
    Abstract: Force, pressure, or stiffness measurement or calibration can be provided, such as by using a graphene or other sheet membrane, which can provide a specified number of monolayers suspended over a substantially circular well. In an example, the apparatus can include a substrate, including a substantially circular well. A deformable sheet membrane can be suspended over the well. The membrane can be configured to include a specified integer number of one or more monolayers. A storage medium can comprise accompanying information about the suspended membrane or the substrate that, with a deflection displacement response of the suspended membrane to an applied force or pressure, provides a measurement of the applied force or pressure.
