Abstract
This invention provides a digital microfluidic manipulation device and a manipulation method thereof. This device comprises a PDMS membrane having a surface comprising a plurality of hydrophobic microstructures; a plurality of air chambers arranged in an array and placed under the PDMS membrane; and a plurality of air channels, each of which connects to a corresponding one of the plurality of air chambers. When a suction force is transmitted via one of the plurality of air channels to the corresponding air chamber, a portion of the PDMS membrane above the air chamber deforms toward the air chamber, so that the surface morphology and the contact angle of the liquid/solid interface of the surface comprising the plurality of hydrophobic microstructures are altered and thereby to drive droplets.
