Abstract

The invention discloses a preparation method of an electrogenerated chemiluminescence furazolidone biosensor and belongs to the technical field of novel nano functional materials and biological sensors. A novel two-dimensional nano composite material Mn-TiO2 / g-C3N4 is prepared first, the material is loaded with furazolidone antibodies by means of good biocompatibility and large specific surface area, then by means of the cross-linking effect of glutaraldehyde, horse radish peroxidase can catalyze hydrogen peroxide to generate oxygen enzyme in situ in detection, an electrochemical reaction is performed on a base solution, a high and stable electrogenerated chemiluminescence signal is generated, by means of influences of specific quantitative combination of antibodies and antigens on electron transmission capacity, the electrogenerated chemiluminescence signal is correspondingly reduced, finally the low-cost, high-sensitivity and good-specificity electrogenerated chemiluminescence biosensor for detecting furazolidone is prepared, and the biosensor is fast in detection and easy to prepare.

Description

Technical field [0001] The present invention involves a preparation method for electrochemical chemical glowing furazolidone biosensor.It belongs to the new type of nano -functional materials and biosensor technology. Background technique [0002] Aurazolidone (Di Ling) is a nitro -amura antibiotic, which is a broad -spectrum antibacterial drug.When used as veterinary drugs, amuoloone has good effects on preventing and treating certain raw diseases, water mold, bacterial gills, red dermatology, and hemorrhage disease.In the breeding industry, amurazolidone can be used to treat livestock and poultry intestinal infections, such as piglets yellow and white diarrhea.In the water industry, amuoloone has a certain effect on salmonia infection brain adhesion.However, the Ministry of Agriculture in my country lists amuolorazolidone as prohibited drugs and cannot be detected in animal food.The FDA also banned the use of nitro -amu) in animal food in animal food in 2002. [0003] At presen...
