Abstract
Provided is a digital microfluidic device for quick polymerase chain reaction. The digital microfluidic device includes an enclosed chamber for holding droplets comprising PCR mixtures. The chamber has an upper layer and a lower layer, which provide a top heater and a bottom heater contained in a thermal electrode respectively to form dual heaters. The lower layer further has an array of electrodes and a dielectric layer, e.g. Norland Optical adhesive 61, coating thereon. Such arrangement of the digital microfluidic device allows quick and homogeneous heating of droplets to lower the heating voltage, shorten the reaction time, and prevent the dielectric layer from breakdown during the thermal cycle.
