High Purity Colloidal Gold Nano Gold Solution CAS 7440-57-5

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 high purity raw material and a new processing technology that reduces the particle size to 15nm. This greatly enhances gold's inherent characteristics, such as its catalytic, anti-free radical, dispersion, etc.

The symbol of 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 precious metals. It has an atomic number of 196.96654 and a face-centered cubic structure.
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 7440-5:

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;
Add 0.01 - 0.5% hydrazine hydroxide aqueous to the mixed solution in Step 1 while stirring. Stop adding hydrazine solution when the pH reaches 6.8-7.0. Continue stirring for 20-30 minutes until you get a nanoscale gold solution. This preparation method is advantageous because it can be carried out at any temperature and is very simple. The gold nanoparticles that are in the solution are 10 to 100nm.

Gold nanoparticles application
Gold nanoparticles' unique biochemical, physicochemical, and genetic properties enable them to have a role that is unique in many areas, such as immunoanalysis and biosensors. They can also be used 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 identifying genetic material.
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 mask, toothbrush and nanometer-gold soap.

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. Nanoparticle solutions consist of suspensions of microparticles suspended in water. 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.

Shipping & Packing of Colloidal Gold nano Gold Solution
The packaging we use depends on the quantity of colloidal Gold.
Packing: 100ml/bottle. 250ml/bottle. 1000ml/bottle. Or as per your request.
