Description:

With the development of nanotechnology, as an important member of the nanofamily, nanogold has not only the general properties of nanomaterials, but also unique physical and chemical properties such as good optical properties, biocompatibility and catalytic activity.

Gold nano-powder has high electron density, dielectric characteristics and catalytic effect, and can be combined with a variety of biological macromolecules without affecting its biological activity.

Nano-gold has good stability, small size effect, surface effect, optical effect and unique biological affinity. It has a wide range of applications in the fields of industrial catalysis, biomedicine, bioanalytical chemistry, and rapid detection of food arrangements. At present, many scholars have carried out related research on the application of nano-gold colloid in biomedicine and other fields.

Storage Condition:

Gold nano-powder be stored in a dry, cool environment, should not be exposed to the air to avoid anti-tide oxidation and agglomeration.
