Abstract

Described herein are digital microfluidic (DMF) devices and corresponding methods for managing reagent solution evaporation during a reaction. Reactions on the DMF devices described here are performed in an air or gas matrix. The DMF devices include a means for performing reactions at different temperatures. To address the issue of evaporation of the reaction droplet especially when the reaction is performed at higher temperatures, a means for introducing a replenishing droplet has been incorporated into the DMF device. A replenishing droplet is introduced every time when it has been determined that the reaction droplet has fallen below a threshold volume. Detection and monitoring of the reaction droplet may be through visual, optical, fluorescence, colorimetric, and/or electrical means.
