Abstract
A device for dispensing one or more microdroplets is provided. The device comprising a microfluidic chip having an oEWOD structure configured to create an optically-mediated electrowetting (oEWOD) force, the microfluidic chip includes a first region and a second region, wherein said first and second regions are separated by a constriction; wherein the first region is adapted to receive and manipulate one or more microdroplets dispersed in a carrier fluid at first flow rate; and wherein the second region is configured to receive the microdroplet via the constriction from the first region and transfer said microdroplet to an outlet port of the microfluidic chip in a second flow rate; wherein the second region is configured to receive said microdroplet via the constriction from the first region by application of an optically -mediated electrowetting (oEWOD) force; and wherein the second flow rate in the second region is higher than the first flow rate in the first flow region. A method and apparatus for dispensing one or more microdroplets are also provided.
