  • Method of detecting molecules
    Patent number: 8691499
    Abstract: Method of detecting molecules, using a sensor having a membrane layer having parallel pores extending through the membrane layer and incorporating therein probe molecules that bind with corresponding target molecules when present in the pores, electrodes, and an ionic solution in contact with the electrodes and the pores, wherein the electrodes are energized to induce an electrical current in the solution through the pores, wherein the electrical current induces an electrical parameter in the electrodes that is indicative of a through-pore electrical impedance of the pores, wherein the through-pore electrical impedance is increased when there is probe-to-target molecule binding in the pores relative to when there is an absence of such binding.
    Type: Grant
    Filed: January 27, 2011
    Date of Patent: April 8, 2014
    Assignee: The Johns Hopkins University
    Inventor: Stergios Papadakis
