Abstract
A process and device for electrostatically controlling an ionic environment in a droplet, such as in a droplet-based platform including polymerase-chain reaction (PCR) applications. The process includes providing a chip that comprises at least a pair of electrodes, placing a salt-containing droplet on the chip, and then applying a bias across the electrodes to accumulate ions near surfaces of the electrodes, thereby depleting a bulk salt concentration in regions of the droplet away from the electrodes.
