  • Graphene-based field-effect transistor biosensors
    Patent number: 9676621
    Abstract: The disclosure provides a field-effect transistor (FET)-based biosensor and uses thereof. In particular, to FET-based biosensors using thermally reduced graphene-based sheets as a conducting channel decorated with nanoparticle-biomolecule conjugates. The present disclosure also relates to FET-based biosensors using metal nitride/graphene hybrid sheets. The disclosure provides a method for detecting a target biomolecule in a sample using the FET-based biosensor described herein.
    Type: Grant
    Filed: February 17, 2012
    Date of Patent: June 13, 2017
    Assignee: UWM Research Foundation, Inc.
    Inventors: Junhong Chen, Shun Mao, Ganhua Lu
  • Controlled decoration of carbon nanotubes with aerosol nanoparticles
    Patent number: 8268405
    Abstract: The present invention addresses the problem of conveniently and efficiently decorating nanostructures such as carbon nanotubes with aerosol nanoparticles using electrostatic force directed assembly (“ESFDA”). ESFDA permits size selection as well as control of packing density spacing of nanoparticles. ESFDA is largely material independent allowing different compositions of such nanoparticle-nanotube structures to be produced.
