Module for detecting analytes in fluids and chip having the same

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.

1. A chip for detecting analytes in fluids, the chip comprising:
a sample inlet extending outside of the chip; and a sample outlet extending outside of the chip, wherein the chip has a structure where the sample inlet and the sample outlet communicate with each other through a module, the module comprising: a sample injecting part for injecting a sample fluid; a filtering zone configured to remove noise materials from the sample fluid, the filtering zone having a height lower than that of the noise materials; and a reaction zone arranged to perform a reaction to detect the analytes in the sample fluid, wherein the filtering zone and the reaction zone are included in a closed microchannel, through which the sample fluid moves due to capillary floating, wherein an expanding part, which has an expanded space having a sectional area larger than a sectional area of the microchannel, is formed at a part or whole part of each inner wall of both sides of the microchannel of the module.
