Nano-gold is made from high-purity, pure gold. This gold is then reduced to a particle size of less than 15nm using a new, special processing technique, which enhances the intrinsic properties of gold. Purity: 1000ppm
Particle size: 5-15nm

The following is a list of the most recent articles about Colloidal Gold Nano Gold Solution:
Colloidal gold benefits:
Nanogold The gold is processed using a high purity raw material and a new technology that reduces the particle size to 15nm. This greatly enhances the gold's intrinsic properties such as its catalytic, anti-free radical, and dispersion effects.

Gold is Au. The gold symbol is Au. Properties of Gold Include high security and stability, as well as oxidation resistance and corrosion resistance.
Gold is one the rarest, most valuable metals. It has an atomic number of 196.96654 and a face centered cube.
Physical properties of gold
Gold melting point: 1064.43. Gold boiling temperature: 2808. electronegativity: 2.54, covalent radius: 1.34A, ion radius: 0.85 (+3) A, atomic radius: 1.46A, atomic volume: 10.2cc/mol.
Due to their close atomic distances, gold can form alloys. The atomic radius for gold is 1.46 Mr. These alloys do not consist of compounds but are solid melts.

Product Performance of Colloidal Gold Nano Gold Solu-tion CAS 744057-5

Colloidal Gold is made by dispersing nano-sized gold particles, 15nm and smaller, into water. The end result will be a stable, neutral color with uniformity. The nano gold solution looks faintly red and not golden brown. By adding other substances, the liquid gold appears blue when it is in a condensed form. The solution can be consumed by humans and is completely safe for contact with the skin.

What is Colloidal Gold Nano Gold Solution Produced?
Preparation of gold nanoparticles is done as follows:
1) adding gold chloric acid in deionized water, and adding polyvinylpyrrolidone, sodium dodecyl sulfate, gold chloric acid, polyvinylpyrrolidone and sodium dodecyl sulfate at mass concentrations of 0.01 ~ 1.0%,0.02 ~ 2.0% and 0.0001 ~ 1.0%, respectively;
2) Stirring at room temperature, add 0.01-0.5% hydrazine hydroxide aqueous to the mixed solution in Step 1, adding the hydrazine solution. Stop adding hydrazine solution when the pH reaches 6.8-7.0. Stir for 20-30 minutes until a gold nanoscale is obtained. The following are the advantages of using this method: the preparation can be carried out at any temperature, it's simple, and the gold nanoparticles that are in the solution are 10 to 100 nm.

Gold nanoparticles application
Gold nanoparticles' unique biochemical, physicochemical, and genetic properties enable them to have a role that is unique in immunoanalysis. They can be used as biosensors for DNA recognition, detection, and gene expression. Gold nanorods can adsorb DNA and proteins, but will not alter their properties. Gold nanorods, as a carrier of excellent properties, have been extensively studied.
Food, glass and living organisms coloring agent.
A technique for genetic identifiers.
This is used to refine environmental purification materials.
The preservative is used to preserve food and cosmetics.
Add cosmetics with anti-aging effect, whitening, and moisturizing.
Production of medical equipment, health care supplies, beauty equipment.
We produce a wide range of everyday necessities, foods and drinks that are very closely linked to the people's lives. If the beauty masks are made of nanometer-sized gold soap, toothbrushes and all other kinds of cosmetics.

Store Colloidal Gold Nano Gold solution in the following conditions:
1. Colloidal Gold should not be exposed to sunlight.
2. The product is intended for research or development purposes and the person using it must be a qualified professional.
3. Nanoparticles are suspended in water to form nanoparticle solutions. These dispersions are either used in their original form or can be diluted with compatible (compatible) solvents. The nanoparticles can settle in dispersions during storage. If this happens, you can shake them up (mix) before using.
