| 摘要 |
The present invention is directed to a microfluidic biochip based on an agglutination reaction that is frequently used in qualitative typing in the diagnostic medicine field by realizing a specimen inlet, a reagent inlet, a split microchannel, transfer microchannels, a chaos micromixer, a reaction microchamber, a microfilter, a passive microvalve, and an outlet on a plastic microchip. Particularly, the biochip of the present invention is characterized in that portability thereof is superior and a small amount (about 1 mul) of each of a specimen and a reagent is used. In addition, the biochip of the present invention can be cheaply made through conventional photolithography, electroplating, injection molding, and bonding. Therefore, by utilizing the microfluidic biochip for blood typing according to the present invention, a point-of-care diagnosis for performing blood typing based on an agglutination reaction at any place becomes possible.
