  • Patent number: 9557294
    Abstract: A method of analyzing a molecule in a nanopore is disclosed. A voltage is applied across a nanopore that is inserted in a membrane by coupling the nanopore to a voltage source. The nanopore is decoupled from the voltage source. After the decoupling, a rate of decay of the voltage across the nanopore is determined. A molecule in the nanopore is distinguished from other possible molecules based on the determined rate of decay of the voltage across the nanopore.

  • Patent number: 9551697
    Abstract: A method of identifying a molecule is disclosed. A molecule is drawn to a nanopore by applying a first voltage signal to a pair of electrodes during a first period, wherein the first voltage signal causes a first ionic current through the nanopore that is indicative of a property of a portion of the molecule proximate to the nanopore. The molecule is released from the nanopore by applying a second voltage signal to the pair of electrodes during a second period, wherein the second voltage signal causes a second ionic current through the nanopore. The first period and the second period are determined based at least in part on a net ionic current through the nanopore comprising the first ionic current and the second ionic current.

  • Publication number: 20160178554
    Abstract: A method of analyzing a molecule is disclosed. A voltage source is selectively connected to or disconnected from a capacitor using a switch controlled by a reset signal. A charge is stored in a capacitor when the voltage source is connected to the capacitor. The capacitor is discharged through a nanopore in a membrane when the voltage source is disconnected from the capacitor. A duty cycle of the reset signal is determined such that the voltage source and the capacitor is connected for at least a one tenth portion of a reset signal period and disconnected for a remaining portion of the reset signal period, such that a voltage across the nanopore is maintained at a higher level during the portion of the reset signal period in which the connection is maintained than during the remaining portion of the reset signal period in which the connection is not maintained.
