Publication number: 20230158503Abstract: Droplet interfaces are formed between droplets in an electro-wetting device comprising an array of actuation electrodes. Actuation signals are applied to selected actuation electrodes to place the droplets into an energised state in which the shape of the droplets is modified compared to a shape of the droplets in a lower energy state and to bring the two droplets into proximity. The actuation signals are then changed to lower the energy of the droplets into the lower energy state so that the droplets relax into the gap and the two droplets contact each other thereby forming a droplet interface. The use of sensing electrodes in the device permit electrical current measurements across the droplet interface. The sensing electrodes can be used for either (i) applying a reference signal during droplet actuation or (ii) recording electrical current measurements.Type: ApplicationFiled: November 18, 2022Publication date: May 25, 2023Applicants: Oxford Nanopore Technologies PLC, Sharp Life Science EU (Ltd)Inventors: Matthew Holden, James White, Andrew John Heron, James Anthony Clarke, Jason Robert Hyde, Benjamin James Hadwen, Sally Anderson

Publication number: 20220326137Abstract: The disclosure provides a method of manipulating droplets in an electro-wetting on dielectric (EWOD) device. Electro-wetting electrodes of the EWOD device are selectively actuated to: cause first and second droplets in a fluid medium in the fluid chamber of the EWOD device to contact each other to form a droplet interface bilayer, the first droplet containing fluid of a first composition including a first solute species and the second droplet containing fluid of a second composition different to the first composition, maintain the first and second droplets contacting each other to maintain the droplet interface bilayer and thereby allow the first solute species to pass from the first droplet to the second droplet via the DIB; and cause the first droplet to separate from the second droplet. This method aspect results in transfer of solute from the first droplet to the second droplet.Type: ApplicationFiled: June 25, 2020Publication date: October 13, 2022Inventors: Sally ANDERSON, Benjamin James HADWEN, Stan KWANG

The pixel circuit includes a sensing electrode, a first gate electrically connected to the sensing electrode, a second gate in electrical communication with the first gate, and a readout device that is electrically connected to the second gate. An input voltage applied to the sensing electrode is amplified between the first gate and the second gate, the amplification being measured as an output signal from the readout device to perform a sensing operation. For example, the output signal may be relatable to pH, analyte measurements, or other properties of sample liquids analyzed by the sensing device. A sensing device may include multiple pixels disposed on a substrate, each pixel including said pixel circuit. Driver circuits controlled by control electronics are configured to generate signals that selectively address the pixels and to read out voltages at the sensing electrodes.Type: GrantFiled: August 13, 2018Date of Patent: February 25, 2020Assignee: Sharp Life Science (EU) LimitedInventors: Benjamin James Hadwen, Campbell Donald Brown, Christopher James Brown, Gregory Gay, Sally Anderson
