  • Methods and related systems for carbon nanotube deposition
    Patent number: 7381316
    Abstract: Deposition of individual carbon nanotubes using a combined ac and dc composite field, and a circuit apparatus for use therewith.
    Type: Grant
    Filed: April 30, 2003
    Date of Patent: June 3, 2008
    Assignee: Northwestern University
    Inventors: Junghoon Lee, Jaehyun Chung
  • Micro/nano-fabricated glucose sensors using single-walled carbon nanotubes
    Patent number: 7118881
    Abstract: A novel glucose sensor utilizing hydrogen-specific gas sensing capability of single walled carbon nanotubes assembled on microelectrodes. Highly specific glucose sensing was demonstrated using buffered sample solutions with clinically significant concentrations. The approach enables a simple but powerful bio-sensor reliably operating with a completely new principle, and opens up novel device applications where functional nano-components can be integrated into a bioMEMS device.
    Type: Grant
    Filed: December 5, 2003
    Date of Patent: October 10, 2006
    Assignee: Northwestern University
    Inventors: Junghoon Lee, JaeHyun Chung, Kyong-Hoon Lee
  • Thin membrane transducer
    Patent number: 7086288
    Abstract: A transducer includes a substrate and a thin membrane having a shape that can be deflected relative to the substrate to provide an amount of membrane deflection useful for sensing or actuation purposes.
    Type: Grant
