|Title:||MICROCHIP FOR ANALYZING FLUIDS|
The present invention provides a microchip for analyzing fluids which is composed of a body part having a top surface and a bottom surface and is for detecting a specific antigen in a fluid by flowing the fluid through an inner channel formed between the top surface and the bottom surface, the microchip comprising: an input channel configured so that an assay sample is injected via a hole passing through the top surface; a reaction channel which is configured to communicate with the input channel via the fluid and to have a higher height than the bottom surface forming the input channel, and includes a magnetic particle to which a first antibody involved in a first antigen-antibody reaction with the assay sample flowing from the input channel is fixed, the magnetic particle participating in the first antigen-antibody reaction so as to form an immune complex; and a detection channel which is configured to communicate with the reaction channel via the fluid and has a longer length and a narrower width than the input channel or the reaction channel, and in which a second antibody involved in a second antigen-antibody reaction with the immune complex flowing from the reaction channel is fixed.
