  • Patent number: 10132773
    Abstract: Specific ionic interactions with a sensing material that is electrically coupled with the floating gate of a floating gate-based ion sensitive field effect transistor (FGISFET) may be used to sense a target material. For example, an FGISFET can use (e.g., previously demonstrated) ionic interaction-based sensing techniques with the floating gate of floating gate field effect transistors. The floating gate can serves as a probe and an interface to convert chemical and/or biological signals to electrical signals, which can be measured by monitoring the change in the device's threshold voltage, VT.
    Type: Grant
    Filed: December 5, 2008
    Date of Patent: November 20, 2018
    Assignee: New York University

  • Patent number: 7435852
    Abstract: Methods for preparing an oligomer exhibiting supramolecular extension of ?-conjugation are described. The manipulation of intra-oligomeric properties such as ?-conjugation length and the precise architecture(s) resulting from inter-oligomeric variations resulting from supramolecular chemistry offers great promise in the design of nanoscale devices. As shown, self-assembly of the supramolecular structure can be induced by causing a molecule: dopant molar ratio to go beyond the predicted theoretical fully-doped molar ratio.
