Aurosol test paper used for quickly detecting betamethasone residue and preparation method thereof

Abstract

The invention discloses an aurosol test paper used for quickly detecting betamethasone residue and a preparation method thereof. The test paper includes a box body, a test paper strip, a sponge holder and a holder, wherein the test paper strip absorbs envelope antigen and betamethasone polyclonal antibody labeled by the aurosol. The invention overcomes the defects of a betamethasone physical and chemical analysis method such as complex operation, high detection cost, slow speed and secondary environment pollution, and can accurately and sensitively detect the betamethasone residue in water, meat products and milk products. Besides, with little time consumed in the simple pretreatment process of samples, the invention can simultaneously and quickly detect a great quantity of samples.

Description

technical field [0001] The invention relates to a colloidal gold test paper for rapid detection of betamethasone residues and a preparation method thereof. Background technique [0002] Betamethasone, a veterinary drug, is a glucocorticoid drug that has good anti-inflammatory effects and can fight against inflammation caused by various reasons such as physical, chemical, physiological, immune, etc. In addition, it can also improve the feed conversion rate, thereby increasing animal body weight, and has a synergistic effect with β-agonists and other steroid hormones. The unreasonable use of glucocorticoids as growth-promoting agents, or careless withdrawal periods when used as veterinary drugs may eventually lead to the residue of glucocorticoids in animal-derived foods, which constitutes a potential hazard to human health. [0003] The conventional analysis method of the glucocorticoid betamethasone residue is mainly an instrument method such as liquid chromatography. This ...

AI Technical Summary

Problems solved by technology

The unreasonable use of glucocorticoids as growth-promoting agents, or the use of veterinary drugs without paying attention to the withdrawal period may eventually lead to the residue of glucocorticoids in animal-derived foods, which constitutes a potential hazard to human health.

[0003] The conventional analysis method of the glucocorticoid betamethasone residue is mainly an instrument method such as liquid chromatography. This traditional analysis method not only requires an expensive gas chromatograph, but also has slow analysis speed and high cost, and is not suitable for rapid screening of a large number of samples. and promote the application at the grassroots level

Moreover, the sample pretreatment procedure is relatively complicated, requiring the use of a large amount of organic solvents, resulting in secondary pollution

With the rapid increase in the number of samples to be tested, especially the samples that require rapid on-site testing, traditional veterinary drug residue analysis methods are difficult to meet the requirements
