Flow injection illuminating detection device

Abstract

The invention discloses a flow injection luminescent detection device, which comprises a base, a reference electrode, an auxiliary electrode and a working electrode. A detection cavity with an opening at the bottom is arranged inside the base, and the reference electrode and the auxiliary electrode are arranged along the base. Axially arranged in the base, one end of the reference electrode and the auxiliary electrode is suspended in the detection cavity, the other end of the reference electrode and the auxiliary electrode protrudes from the upper end surface of the base, and the working electrode is formed by Made of transparent material, the working electrode is fixed on the bottom wall of the base and is in contact with the detection chamber, the working electrode seals the bottom of the detection chamber, and two through holes are opened radially on the peripheral wall of the base, the The through hole communicates with the detection chamber. The invention solves the problem of constructing the bionano sensing interface in the flow injection chemiluminescence / electrochemiluminescence system, and realizes the highly selective and sensitive detection of biomolecules in the automatic flow injection chemiluminescence / electrochemiluminescence system.

Description

technical field [0001] The invention relates to the field of biochemistry, in particular to a flow injection luminescent detection device. Background technique [0002] In the prior art, when the biological nano-sensing interface is constructed in the chemiluminescence / electrochemiluminescence system, when the nanomaterials or biomolecules are detected after waiting for the detection substance to be fixed, the detection is performed separately according to the needs of different detection reagents, resulting in repeated operations. Many, affect the efficiency of the experiment. Due to the similarity of the detection process, whether flow injection chemiluminescence / electrochemiluminescence detection can be realized has been the direction of exploration in this field. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide a flow injection luminescence detection device, which solves the p...
