Abstract
The present invention provides a self-driven microfluidic chip for rapid influenza A detection, said chip comprises: a substrate, a hydrophobic layer, a hydrophilic film layer, and a channel structure layer laminated sequentially, the structure of the channel structure layer includes a plurality of channels, a plurality of valves and reaction tanks in the channels, and a plurality of openings, wherein the hydrophilic film layer includes a pattern corresponding to the structure of the channel structure layer, and forms a disconnected area corresponding to the location of the valves to remain the valves hydrophobic, the channel structure layer is formed of a flexible material, and a height of the valves being higher than the channels in a thickness direction of the channel structure layer, to control liquid flow by pressing the valves.
