Abstract
The present invention provides a micromixer biochip, comprising: a substrate having a surface; a fluidic channel layer disposed above the surface of the substrate, including a mixing chamber and a single-opening fluidic channel, wherein one end of the single-opening fluidic channel is closed and the other end of the single-opening fluidic channel connects to the mixing chamber, and a top portion of the single-opening fluidic channel is made of a flexible material; and an air chamber layer disposed above the top portion of the fluidic channel layer, including an air pore, at least one chamber, and an air channel connecting the chamber and the air pore, wherein the number and position of the air chamber correspond to the number and position of the single-opening fluidic channel of the fluidic channel layer.
