The amantadine colloidal gold rapid detection card, in simple terms, is a rapid detection tool specially designed to detect amantadine residues in food. It is mainly used in animal-derived foods, such as pork, chicken, eggs, etc., to quickly screen for the presence of illegally added amantadine.
In principle, this detection card makes use of colloidal gold labeling technology. Colloidal gold is a gold nanoparticle with strong adsorption capacity and color development properties. During detection, the amantadine in the sample binds to the antibody labeled with colloidal gold to form a complex. When the sample solution moves on the test strip, the complex will compete with the detection line on the test strip (coated with amantadine antigen). If the concentration of amantadine in the sample is high, it will compete with the colloidal gold-labeled antibody to bind the antigen check point of the detection line, resulting in the detection line without color; conversely, if there is no amantadine in the sample or the concentration is low, the colloidal gold-labeled antibody will bind to the detection line antigen to make the detection line color. By observing the color development of the detection line and the quality control line, the result can be quickly judged.
Its advantages are very obvious. The first is "fast", the entire detection process usually only takes 15-30 minutes, greatly shortening the waiting time of traditional detection methods; the second is "Ling", which has high sensitivity and can detect very low concentrations of amantadine residues (generally up to ng level); the third is "simple", the operation steps are simple, no professional equipment and complex operations are required, and non-professionals can get started after simple training; in addition, the cost is relatively low, suitable for large-scale screening use.
In application scenarios, it is widely used in food production enterprises, agricultural product regulatory authorities, scientific research institutions, etc. Through it, enterprises can quickly control the quality of raw materials and products, regulatory authorities can efficiently screen illegal products in market sampling, and scientific research institutions can use it for relevant residue research.
In general, the amantadine colloidal gold rapid detection card has become an important technical means for the food industry to ensure safety and combat illegal additions by virtue of its fast, sensitive and easy operation. It plays a key role in protecting the "safety on the tip of the tongue" of consumers.
