Abstract
A method for degassing a microfluidic droplet by combining electrowetting and heating to induce formation of gaseous bubbles in the droplet. In an embodiment the methods are carried out on an active matrix of electrowetting electrodes including a hydrophobic coating. A carrier fluid is flowed against the droplet motion propelled by electrowetting to facilitate rapid removal of the gasses departing the droplet.
