技術說明

本發明揭示一種微流體之網路式微通道裝置，可應用於生醫檢測之用途，其係在一基材(substrate)上形成複數個行列式的三維微通道(micro channel)。該三維微通道結構係利用高分子微機電(polymer-MEMS)之技術製造，將不同之高分子或半導體材料以光蝕刻微影法疊層余該基材上，特別是構成一種埋置式之中空的微通道。該微通道因尺寸因素產生驅動流體移動之表面張力，並利用其縱橫交錯之網路式結構使得流體自動充滿每個待測定區域。 A microfluidic device has a plurality of H-shaped micro channels not connected to each other and formed on a substrate. Each of the H-shaped micro channels comprises two main channels separately placed on two opposite sides in parallel and a plurality of sub-channels perpendicularly connected to the two main channels. The present invention is designed in such a way that various reagents dropped into different H-shaped micro channels are immobilized on respective sub-channels because of the different widths of the main channel and sub-channel. Afterwards the reagents are coated with a layer of polymer. The polymer has a porous structure that allows the passage of any sample to be tested. Finally, a plurality of upper channels parallel to one another are directly fabricated in the polymer, or in another layer of polymer stacked on the previous polymer.
