Description

technical field [0001] The invention belongs to the technical field of chemiluminescence detection, and in particular relates to an optical detection device, in particular to a direct chemiluminescence optical detection device. Background technique [0002] Immunoassay refers to an analysis method based on specific antigen-antibody reaction. Chemiluminescent immunoassay is an immunoassay technology that has developed rapidly in recent years. Its principle is to use chemiluminescent substances to amplify the signal, and use its luminous intensity to directly measure the immune binding process. Chemiluminescent immunoassay has become an important direction of immunological detection. [0003] In chemiluminescent immunoassays, magnetic particles are often used for immunoassays. Specifically, the antibody a with magnetic particles, the antigen in the sample, and the antibody b with luminescent substances are mixed and reacted at a certain temperature. A sandwich structure is f...
