The present invention provides a microfluidic biochip, which comprises: a fluid transportation unit having a fluid transportation reservoir and a fluid transportation air chamber; a first fluid storage reservoir; a second fluid storage reservoir; a first valve unit having a first valve and a first valve control air chamber; and a second valve unit having a second valve and a second valve control air chamber; wherein the first valve unit is located between the first fluid storage reservoir and the fluid transportation unit, the second valve unit is located between the second fluid storage reservoir and the fluid transportation unit, and the top portion of the fluid transportation reservoir and the valves are made of a flexible material. The structure of the present microfluidic biochip allows fluids to be transported and/or mixed therein.

Microfluidic biochip

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.
