技術摘要: |
本發明提出一種數位微流體操控裝置,包括:一具有疏水性表面的彈性薄膜,其可以是一種具有疏水性微結構的聚二甲基矽氧烷(Polydimethylsiloxane,PDMS)薄膜;複數個氣室,其組成一氣室陣列且置於該彈性薄膜下方;以及複數個氣體傳輸管道,每一氣體傳輸管道各別連接到一對應的氣室。當一抽吸力藉由該氣體傳輸管道傳輸到一對應的氣室時,該氣室上方的彈性薄膜變形,以改變PDMS薄膜的表面形態和固/液介面的接觸角,藉此驅動液滴。
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.
