  • CHARGE DETECTOR AND PROCESS FOR SENSING A CHARGED ANALYTE
    Publication number: 20190137443
    Abstract: A charge detector includes: a charge sensor that senses a charged analyte and produces a charge signal in response to contact with the charged analyte; a transducer in electrical communication with the charge sensor and that: receives the charge signal from the charge sensor; receives a feedback control signal; and produces a transduction signal in response to receipt of the charge signal and the feedback control signal; and a sensitivity controller in electrical communication with the transducer and that: receives the transduction signal from the transducer; produces the feedback control signal in response to receipt of the transduction signal from the transducer; and produces a charge readout in response to receipt of the transduction signal from the transducer.

  • Single molecule filter and single molecule electrograph, and process for making and using same
    Patent number: 10067118
    Abstract: A single molecule filter includes: a membrane including: a first surface; a second surface; and a membrane aperture disposed in the membrane and traversing the membrane from the first surface to the second surface, the membrane aperture provided to communicate a single molecule across the membrane; and a nanotube disposed on the membrane and including: a first end disposed on the first surface of the membrane; a second end disposed distal to the first surface; and a tubular aperture extending along the nanotube from the first end to the second end, the tubular aperture provided to communicate the single molecule from the second end of the nanotube to the membrane aperture.
