Claim 18:
19. A method of operating a digital microfluidic (DMF) apparatus that reduces evaporation and surface fouling, the method comprising: dispensing a coated reaction droplet within an air gap of the DMF apparatus, the DMF apparatus having a bottom plate that is open to air above the bottom plate, so that the coated reaction droplet is combined with a liquid wax or oil material forming the 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 increasing a temperature of the thermally controlled region to allow a reaction to proceed within the coated reaction droplet at the thermally controlled region, wherein the liquid wax or oil material protects the coated reaction droplet from evaporation.
