In agricultural production, as a high-efficiency carbamate insecticide, carbamide is widely used to control pests on vegetables, fruits and other crops, and effectively ensure the yield of agricultural products. However, with the increase in usage, its residue problem has gradually attracted attention - excessive residues may endanger human health, so rapid and accurate detection methods have become an important part of food safety supervision. Carbamide Colloidal Gold Rapid Detection Card is a convenient detection tool developed in response to this demand.

Simply put, Carbamide Colloidal Gold Rapid Detection Card is a real-time detection (POCT) product based on immunochromatography technology, which is mainly used for rapid screening of carbamide residues in foods (such as vegetables, fruits, grains, etc.). Its core principle is the use of antigen-antibody specific binding reaction: detection card contains colloidal gold-labeled carboxyl antibody, when the sample (such as extract) drops into the detection card and the sample hole, if the concentration of carboxyl in the sample reaches a certain threshold, it will compete with the colloidal gold-labeled antibody to bind the naphthol-OVA conjugate on the detection line, resulting in color development of the detection line; conversely, if there is no carboxyl in the sample or the concentration is too low, the detection line does not show color, so as to achieve a quick judgment result.

As a "rapid screening expert" in the field of food safety testing, the Carbonyl Colloid Gold Rapid Detection Card has significant advantages: first, the detection speed is fast, usually 10-15 minutes to produce results, no need for complex instruments; secondly, the operation is simple, no professional training is required, just add samples dropwise according to the instructions and observe the results; furthermore, the cost is low, compared with traditional instrument detection (such as high-performance liquid chromatography), the detection card is inexpensive, suitable for grass-roots detection, on-site rapid screening and other scenarios; in addition, it is highly portable and can be used in the field, market stalls, etc., to provide timely feedback on the detection results and help make quick decisions.

At present, the rapid detection card of methicarb colloidal gold is widely used in agriculture and rural areas, market supervision, food enterprises and other fields, and has become an important "outpost" to ensure the safety of agricultural products. Through rapid screening, food with excessive methicarb residues can be detected in time to avoid entering the market and escort the health of consumers.
