Application of noble metal gold nanopowders in food safety testing:
Noble metal gold nanopowder has many advantages, such as, easy preparation, simple characterization, and high detection sensitivity, it is widely used in the field of food safety detection.
1. Pesticide residues is a big problem in food safety currently. Since synthetic pesticides have been widely used in agricultural production, problems about pesticide residues became increasingly serious and complex. At present, millions of tons chemical pesticides are produced each year in the world, and thousands kinds of synthetic compounds are used in agricultural production, so pesticide pollution caused by these is always threatening human health. Gold nanopartcle has high sensitivity, and can be used as immune markers to detect pesticide residues, this solved the problem of pesticide residues on food safety very well.
2. Noble metal gold nanopowder can also detect veterinary drug residue in meat products. Residue of veterinary drug is not only original drug as we understand, it in fact also includes drug metabolites produced by reactions in body. Residue of veterinary drug has great harm, generally it will not make you sick immediately, but if you eat meat products with residual veterinary drug for a long time, the residue will accumulate in body, which can eventually lead to a series of toxic reactions, such as allergies. Besides, some residues of pesticides are also carcinogenic, teratogenic and mutagenic. Therefore, it is urgently needed to find a fast, sensitive and simple detect method for residue of veterinary drug. gold nanoparticle has been widely used in this detection, greatly reduced human diseases.
3. In addition, Au nanoparticle is also widely used in the detection of biotoxins and heavy metal ions.
