  • Contact-line-driven microfluidic devices and methods
    Patent number: 10940478
    Abstract: In order to expand capabilities of anisotropic ratchet conveyor (ARC) systems beyond those of the simple systems that include only a single track of consistent rung spacing, disclosed herein are ARC devices, systems, and methods related to ARC gates that can selectively pause droplet transport; ARC switches that can select the direction of droplet transport between two tracks, each moving away from an intersection between the two tracks; and ARC junctions that can move a droplet towards, and then through, an intersection between two tracks.
    Type: Grant
    Filed: January 23, 2017
    Date of Patent: March 9, 2021
    Assignee: University of Washington
