  • Methods and systems for enhanced microfluidic processing
    Patent number: 10955067
    Abstract: Methods and systems are provided for a microfluidic cartridge including a high performance actuator useful for analyte detection, labeling and analysis. Microfluidic processing systems are to carry out chemical or biochemical reactions, or sequences of reactions, with small volumes (typically between 1 microliter and 10 milliliters) of reactants and products. A microfluidic processing system can comprise a network of tubes interfaced with discrete components such as valves and sensors, or an integrated device made of plastic, glass, metal, or other materials, or a combination of materials, with components such as valves and sensors built into the device and connected by flow passageways formed in the material.
    Type: Grant
    Filed: March 3, 2014
    Date of Patent: March 23, 2021
    Assignee: Wave 80 Biosciences, Inc.
    Inventors: Daniel Laser, Amy Droitcour, Hailemariam Negussie, William Behnke-Parks
  • Long-Throw Microfluidic Actuator
    Publication number: 20190017629
    Abstract: A microfluidic device includes a three-dimensional slat structure having a plurality of interstices configured to generate a high power, high flow rate of fluids by electroosmotic flow. The microfluidic device includes a housing for holding and moving fluids through the slat structure, and a plurality of electrodes that generate an electric field within the plurality of interstices.
