Abstract
Air-matrix digital microfluidics (DMF) apparatuses and methods of using them to prevent or limit evaporation and surface fouling of the DMF apparatus. In particular, described herein are air-matrix DMF apparatuses and methods of using them including thermally controllable regions with a wax material that may be used to selectively encapsulate a reaction droplet in the air gap of the apparatus; additional aqueous droplets may be combined with the encapsulated droplet even after separating from the wax, despite residual wax coating, by merging with an aqueous droplet having a coating of a secondary material (e.g., an oil or other hydrophobic material) that may remove the wax from the droplet and/or allow combining of the droplets.
