Application for nano gold particles:

The maximum application of nano gold powder that is the nano-gold catalyst. Supported gold nanoparticles catalyst for water gas shift reaction, various reaction system hydrogenation of unsaturated hydrocarbons and certain types of liquid-phase oxidation reaction of alcohols have a good catalyst.

1. When gold nanoparticles deposited on the metal oxide or by co-precipitation manner when the load is high catalytic activity, especially in the low-temperature catalytic oxidation of CO in the process of CO2, which catalyzes the capacity and efficiency is much higher than other precious metals.

2. Load nano-gold particles can catalyze propylene as PO, epoxidation reaction can be completed in just one step, and in addition to the water does not produce other byproducts.

3. A distinctive feature of the gold catalyst is partially hydrogenated very selective hydrogenation reaction of unsaturated hydrocarbons have an important impact.

4. In addition to the activated carbon, but to Al2O3 and TiO2 as the carrier also make gold nanoparticles have high activity and selectivity.

5. On the water – gas shift reaction, the catalytic activity of Au / Fe2O3 and Au / ZrO2 is high, and the higher the degree of crystallinity of the carrier, the higher the catalytic activity.

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.

Gold nanoparticles with  advanced usage as a probe in life science fields:

 Au gold nanoparticles can be used as biomarker, probe, The inorganic nanometer probe

Au gold nanoparticles has very broad prospects in the following life science field:

  1. In nucleic acid testing application
  2. In protein detection application
  3. Immunoassay(IA) application
  4. In cell imaging application
  5. Other fields: drug analysis, metal ions detection, biosensor
