CAS 7440-57-5 Catalyst Nano Gold Powder Au nanoparticle

Specification of Au nanoparticle:

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 Au nanoparticle:

1. Catalysts, advanced decorative building materials, bioengineering and pharmaceutical products, etc.
2. Optical components, stained glass aspects.
3. Biological, medical applications, colloidal gold can be used for biomarker and protein concentration determination. Colloidal gold probes are the latest immunocytochemical identification technology that can be used to detect antigens in situ.
4. Nanogold particles form a strong surface bond with the DNA surface, and have broad prospects for the production of DNA immunosensors and DNA chips. Hydrophilic nanogold particles have greatly improved the corresponding sensitivity of the glucose biosensor catalyzed by glucose oxidase.
5. Nano-sized gold paste can be used in conductive circuits in integrated circuits, especially where high reliability is required, such as medical equipment, computers, satellite radio communications, etc.

Storage conditions:
Au nanoparticle should be sealed and stored in a dry and cool environment. It should not be exposed to the air for a long time, to prevent agglomeration due to moisture, affecting the dispersion performance and use effect, and should avoid heavy pressure, do not contact with oxidant, and transport according to ordinary goods.
