ABSTRACT:
Disclosed herewith is a microchip having a micromixer therein. The mixromixer employs a mixing or extracting structure having (1) a first flow pass provided at a first level of the microchip; (2) a second flow pass provided at a second level of the microchip, which is different from the first level; (3) a third flow pass having a plurality of sub flow passes separately layered at the first level and each having a first end and second end thereof, each sub flow pass being connected to one of the first and second flow passes at the first end thereof; and (4) a fourth flow pass, provided at the first level, connected to the second ends of the sub flow passes so that, at least connecting portions between the fourth flow pass and the sub flow passes of the third flow pass, an extending direction of the fourth flow pass is substantially identical to those of the sub flow passes. By allowing the first liquid to flow from the first flow pass to the fourth flow pass through the third flow pass while the second liquid to flow from the second flow pass to the fourth flow pass through the third flow pass, the first and second liquids are mixed at the fourth flow pass.
