技術說明

一種碟片式濃度調配流道結構,係用以改變一流體濃度調配流道之幾何形狀,以達到能調配到多種特定濃度之流體設計,係於一碟片上設置複數個流體濃度調配流道,並以一密封層加覆,利用一驅動裝置旋轉產生之離心力,藉由第一注入槽及第二注入槽之第一調配流道及第二調配流道流道尺寸不同,當注入一欲調配濃度之流體時,流速依其流道尺寸而分配至各個調配液接收槽中,以得到多種濃度之流體調配之目的。 A disk-like microfluidic structure includes a disk, and a plurality of microfluidic systems formed on the disk and covered by a top sealing layer. Each microfluidic system includes a first and a second supply chamber located near a geometrical center of the disk, and at least one receiving chamber communicably connected to the first and the second supply chambers via a first and a second microchannel, respectively. When the first and the second microchannels have different geometrical sizes and the disk is driven to spin, two fluids separately held in the first and the second supply chambers are centrifugally moved into the receiving chamber via the differently sized first and second microchannels at different speeds and in different quantities to generate in the receiving chamber a fluid mixture having a specific concentration. By changing the geometrical sizes of the first and second microchannels, different concentration fluid mixtures may be generated.
