  • Method of concentrating particles in a liquid droplet using an EWOD device with sensing apparatus
    Patent number: 11524297
    Abstract: A microfluidic system and related methods of operating an electrowetting on dielectric (EWOD) device operate to concentrate particles within a liquid droplet dispensed onto an element array of the EWOD device. The method includes the steps of providing a non-polar liquid onto the element array of the EWOD device; providing a polar liquid droplet onto the element array of the EWOD device within the non-polar liquid, wherein the polar liquid droplet includes particles; and applying an actuation cycle comprising a plurality of actuation patterns, wherein at least one of the actuation patterns includes actuating one or more array element electrodes within a perimeter of the polar liquid droplet, and the particles migrate within the polar liquid droplet to become concentrated within a portion of the liquid droplet at one or more array element electrodes corresponding to one of the plurality of actuation patterns.
