  • METHODS FOR ELECTRO-MECHANICAL TRANSFECTION
    Publication number: 20220347468
    Abstract: Methods, devices, systems, and kits for electro-mechanical cell transfection are provided. A device includes a first electrode, a second electrode, and an active zone therebetween where an electrical potential difference applied to the first and second electrodes generates an electric field in the active zone sufficient to transfect at least a subset of the cells flowing in the active zone.
    Type: Application
    Filed: April 27, 2022
    Publication date: November 3, 2022
    Inventors: Paulo Andres GARCIA, Cullen BUIE, Ross BEIGHLEY, Rameech MCCORMACK, James HEMPHILL, Jessica SIDO, Bethany GRANT
  • DEVICES, SYSTEMS, AND KITS FOR ELECTRO-MECHANICAL DELIVERY AND METHODS OF USE THEREOF
    Publication number: 20220243164
    Abstract: Devices, systems, and kits for cell transfection are provided. A device includes a first electrode, a second electrode, and an electroporation zone therebetween where an electrical potential difference applied to the first and second electrodes generates an electric field in the electroporation zone sufficient to transfect at least a subset of the cells in the flow path. Methods of introducing a composition into at least a portion of a plurality of cells using the devices, systems, and kits of the invention are also provided.

  • Fuel cell with electroosmotic pump
    Patent number: 7799453
    Abstract: Water flooding at the cathode of a fuel cell is a common problem in fuel cells. By integrating an electroosmotic (EO) pump to remove product water from the cathode area, fuel cell power can be increased. Integration of EO pumps transforms the designs of air channel and air breathing cathodes, reducing air pumping power loads and increasing oxidant transport. Hydration of gas streams, management of liquid reactants, and oxidant delivery can also be accomplished with integrated electroosmotic pumps. Electroosmotic pumps have no moving parts, can be integrated as a layer of the fuel cell, and scale with centimeter to micron scale fuel cells.
