Abstract
An immunoassay cartridge is disclosed that can enhance the reliability of an antigen-antibody reaction while increasing a speed of an antigen-antibody reaction. An immunoassay cartridge includes a reaction chamber and a fluorescence sensor assembly. A plurality of antibodies or antigens is attached to an inner surface including a bottom surface of the reaction chamber closest to the sensor. The fluorescence sensor assembly is disposed on a bottom surface of the reaction chamber. Since the bottom surface of the reaction chamber and the upper surface of the fluorescence sensor assembly are arranged to coincide with each other, even if fluid is repeatedly moved in a first direction after the fluid moves in a second direction in the reaction chamber and then moved in the first direction, there is no obstacle in the movement of the fluid. Thus, it is possible to increase the probability of antigen-antibody reaction in the reaction chamber.
