Patents by Inventor Walter Reisner

Walter Reisner has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11224842
    Abstract: The apparatus for making a nanopore in a membrane generally has an electrode configured to connect to one of two opposing surfaces of the membrane; a conductive tip configured to contact a location of the other one of the two opposing surfaces of the membrane; and a voltage source electrically connected between the electrode and the conductive tip and operable to generate an electric potential across the membrane, the electric potential locally removing material of the membrane at the location to make the nanopore.
    Type: Grant
    Filed: May 17, 2018
    Date of Patent: January 18, 2022
    Assignee: THE ROYAL INSTITUTION FOR THE ADVANCEMENT OF LEARNING / MCGILL UNIVERSITY
    Inventors: Peter Grutter, Yuning Zhang, Yoichi Miyahara, Walter Reisner

  • Patent number: 10307769
    Abstract: There is described herein methods and devices for confining and/or manipulating molecules. At least one molecule is introduced into a fluidic chamber. The fluidic chamber is formed inside a device comprising at least one first electrode having a first surface spaced from at least one second electrode having a second surface facing the first surface. The at least one second electrode has a plurality of dielectric structures arranged to form openings along the second surface. At least one electrical signal is applied across the at least one first electrode and the at least one second electrode to generate a non-uniform electric field having electric field lines extending from the first surface of the at least one first electrode to the second surface of the at least one second electrode in the openings formed between the dielectric structures. The at least one electrical signal has a frequency level causing the at least one molecule to move inside the fluidic chamber in accordance with a predetermined movement.
