SELF-DRIVEN MICROFLUIDIC CHIP FOR RAPID INFLUENZA A DETECTION

A self-driven microfluidic chip for rapid influenza A detection is provided. The chip includes: 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 chambers 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 make the valves hydrophobic; the channel structure layer is formed of a flexible material, and heights of the valves are higher than those of the channels in a thickness direction of the channel structure layer in order to control liquid flow by pressing the valves.
