Patent number: 11507135Abstract: A molecular scrivener reads data from or writes data to a macromolecule and includes: a pair of shielding electrodes; a scrivener electrode between the first and second shielding electrodes and that electrically floats at a third potential that, in an absence of a charged or dipolar moiety of the macromolecule, is intermediate between the first and second potentials and changes in a presence of the charged or dipolar moiety; a dielectric layer interposed between shielding electrodes and the scrivener electrode; and a nanopore that communicates the macromolecule through the electrodes and dielectric layers. Reading data from or writing data to a macromolecule includes: sequentially receiving, at the scrivener electrode, individual moieties of the macromolecule so that the third potential responds to individual moieties; communicating the macromolecule from the scrivener electrode to the second shielding electrode and from second shielding electrode to expel the macromolecule from the nanopore.Type: GrantFiled: April 15, 2019Date of Patent: November 22, 2022Assignee: GOVERNMENT OF THE UNITED STATES OF AMERICA, AS REPRESENTED BY THE SECRETARY OF COMMERCEInventors: Kin P Cheung, Joseph W Robertson, John J Kasianowicz

Patent number: 9921174Abstract: Systems and methods for controlling the temperature of small volumes such as yoctoliter volumes, are described. The systems include one or more plasmonic nanostructures attached at or near a nanopore. Upon excitation of the plasmonic nanostructures, such as for example by exposure to laser light, the nanoparticles are rapidly heated thereby causing a change in the ionic conductance along the nanopore. The temperature change is determined from the ionic conductance. These temperature changes can be used to control rapid thermodynamic changes in molecular analytes as they interact with the nanopore.Type: GrantFiled: September 26, 2016Date of Patent: March 20, 2018Assignees: THE UNITED STATES OF AMERICA, AS REPRESENTED BY THE SECRETARY OF COMMERCE, THE NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGYInventors: John J.

Publication number: 20100122907Abstract: A nanopore conductance measurement method and system is provided. The system has reservoirs of conductive fluid separated by a resistive barrier, which is perforated by a single nanometer scale pore commensurate in size with an analyte molecule in at least one of the reservoirs. The system is configured to have an ionic current driven across the reservoirs by an applied potential and the pore may be treated so that the pore surface can form associations with the analyte molecules of interest to increase the analyte molecule residence times on or in the pore. The system also comprises a means of measuring the ionic current, which current may be either direct or alternating in time, induced by an applied potential between electrodes in the conductive fluid, on each side of the barrier.Type: ApplicationFiled: May 5, 2009Publication date: May 20, 2010Inventors: Vincent M. Stanford, John J. Kasianowicz, Joseph W.F. Robertson, Claudio G. Rodrigues, Oleg V. Krasilnikov
