Description

technical field [0001] The invention relates to a method for regenerating and cleaning indium tin oxide electrochemiluminescence reaction electrodes in the technical field of electrochemiluminescence biological detection. Background technique [0002] Chemiluminescence (electrochemiluminescence) is the luminescent phenomenon produced in the process of chemical reaction. Electrochemiluminescence research began in the 1930s. In 1929, Harvey et al. discovered that electrolysis of luminol under alkaline conditions could produce luminescence on the electrode, and related researches have been carried out since then. The appearance of ruthenium pyridine electrochemiluminescent system in the 1980s was a major progress in this field. Since then, electrochemiluminescence analysis technology has been effectively applied in immunoassay and nucleic acid analysis. [0003] The reaction electrode is one of the important factors involved in the electrochemiluminescence reaction. Traditi...

Problems solved by technology

[0007] (1) Powder grinding method, the most commonly used grinding powder is alumina powder, which can be used alone or combined with ultrasonic cleaning, solution immersion cleaning, etc. The advantage of powder grinding method is that it is simple and direct, and can remove most of the deposits attached to the electrode surface , but this method has disadvantages such as physical damage to the electrode surface and affecting electrode characterization parameters;

[0008] (2) Solution cleaning method, the solution used includes aqueous solution cleaning solution and organic solution cleaning solution. This treatment method is currently the most commonly used ITO electrode surface cleaning method. Its disadvantage is that repeated cleaning steps are required, and it is difficult to find A general-purpose cleaning solution that meets various cleaning requirements at the same time;
