    摘要： Disclosed is a focusing channel device which focuses fluid containing micro particles so that the micro particles flow in a line. The channel device comprises a nozzle formed by left and right walls each of which comprises an inclination surface. The cross sectional area in vertical direction decreases from the entrance of the nozzle toward the exit of the nozzle. The shape of cross sectional view in horizontal direction is asymmetric for the central line in the length direction. Using the focus channel device of the invention, the micro particles in the fluid are not combined with each other and passed through the channel one by one. Thus, blockage of the channel or combination and movement of two particles together does not occur.

    摘要： Disclosed is a fluid analysis chip including a microchannel formed within the chip. The chip includes a sample and a sample outlet communicating with an outside of the chip, and has a structure where the sample inlet and the sample outlet communicate with each other through the closed channel. An expanding part formed in a longitudinal direction of a channel in such a manner that a pair of inner walls corresponding to each other has a larger sectional area at a part or a whole thereof is formed. Therefore, fluids, which pass through the channel adjacent to the expanding part, move while making contact with only another pair of inner walls of the channel, which correspond to each other.

    摘要： Disclosed is a module for rapidly detecting analytes in fluids with high effectiveness and a chip having the module. The module includes a microchannel, which has a filtering zone for removing noise materials and a reaction zone wherein labeling reaction and immobilization reaction for detection of analytes are performed, sample fluid moving through the microchannel due to capillary floating. In a case where the chip having the module is used in detecting analytes in fluids, it is possible to minimize dead volume of sample fluid so that high effective volume ratio can be implemented. Therefore, the chip can be used in detecting analytes from the minimum amount of sample fluid.
