In particular, described herein are air-matrix DMF apparatuses and methods of using them in which a separate well that is accessible from the air gap of the DMF apparatus isolates a reaction droplet by including a cover to prevent evaporation. The cover may be a lid or cap, or it may be an oil or wax material within the well. The opening into the well and/or the well itself may include actuation electrodes to allow the droplet to be placed into, and in some cases removed from, the well. Also 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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Air-matrix digital microfluidics apparatuses and methods for limiting evaporation and surface fouling","description":"Air-matrix digital microfluidics (DMF) apparatuses and methods of using them to prevent or limit evaporation and surface fouling of the DMF apparatus.
