Abstract
The present invention provides a microfluidic chip device for selecting a cell aptamer. The microfluidic chip device comprising a plurality of storage reservoirs; a fluid control unit; a reaction tank; and a PCR reaction tank, wherein each storage reservoir interconnects with the fluid control unit, and via a corresponding pumping/mixing element, the sample and the reagent are mixed and then transported into each storage reservoir. The present invention further provides a method for selecting a cell aptamer.
