Charateristics:

Nano-gold powder is a pure gold nano-powder, and it is an ultra-fine nano-particle produced through a complex physical and chemical process. Safe, environmentally friendly, non-toxic, tasteless, reliable, stable, and easy to disperse. Can be widely used in bio-coloring, biocatalysis, DNA analysis, beauty care and other fields, but also can be used for biological resistance to free radicals, anti-aging and other fields.

Application of precious metal gold nano powder in food safety detection:
The precious metal gold nanopowder has many advantages such as easy preparation, simple characterization, and high detection sensitivity, and is widely used in the field of food safety detection.

1. Pesticide residues are a major issue in food safety. Since synthetic pesticides have been widely used in agricultural production, the problem of pesticide residues has become more and more serious and complicated. At present, millions of tons of chemical pesticides are produced every year in the world, and thousands of synthetic compounds are used in agricultural production. Therefore, pesticide pollution caused by these pesticides has always threatened human health. Gold nanoparticles have high sensitivity and can be used as an immunolabel for detecting pesticide residues, which solves the problem of pesticide residues on food safety.

2. Precious metal gold nanopowder can also detect veterinary drug residues in meat products. Veterinary drug residues are not only the original drugs we know, but also actually include the drug metabolites produced by human reactions. Veterinary drug residues are very harmful and generally do not make you sick immediately, but if you consume meat products containing veterinary drug residues for a long time, the residues will accumulate in the body and may eventually cause a series of toxic reactions, such as allergies. In addition, some pesticide residues are also carcinogenic, teratogenic and mutagenic. Therefore, there is an urgent need to find a fast, sensitive and simple method for the detection of veterinary drug residues. Gold nanoparticles have been widely used in this test, greatly reducing human diseases.
3. In addition, gold nanoparticles are also widely used to detect biological toxins and heavy metal ions.
