Claim 0:
1. A method of operating a digital microfluidic (DMF) apparatus that reduces evaporation and surface fouling, the method comprising:
dispensing a droplet within an air gap of the DMF apparatus having a bottom plate that is open to air above the bottom plate;
combining the droplet with a liquid wax or oil material within the air gap to form a coated reaction droplet;
moving the coated reaction droplet to a thermally controlled region within the air gap by applying energy to a plurality of actuation electrodes; and, allowing a reaction to proceed within the coated reaction droplet at the location, wherein the liquid wax or oil material protects the coated reaction droplet from evaporation.
