Other AbstractThe invention discloses a microfluidic chip based on pneumatic micro pumps and a micro mixer. The microfluidic chip adopts a three-layer structure, a bottom layer is a glass substrate, and a gas drive layer and a liquid flow layer which are made of elastic materials are successively arranged on the substrate; the liquid flow layer comprises a micro mixing chamber, a plurality of micro liquid storage tanks and fluid channels, one end of each fluid channel is connected to the corresponding micro liquid storage tank, and the other end of each fluid channel is connected to the micro mixing chamber; the gas drive layer comprises the micro mixer, a plurality of pneumatic micro pumps and gas channels; externally-added pulse gas pressure is orderly controlled to enter the gas drive layer by an electromagnetic exhaust valve, the pneumatic micro pumps made of the elastic materials and the micro mixer are allowed to work, multiple channels of different solutions are orderly injected into the micro mixing chamber for mixing, so as to realize a purposeful trace chemical reaction. The microfluidic chip can be used for rapid, convenient and accurate realization of automated liquid transport and efficient mixing of a trace liquid, and has important practical significance.
