Colloidal gold benefits:
Nanogold The gold is processed using high purity raw material and a new technology that reduces the particle size to 15nm. This greatly enhances gold’s inherent characteristics, including its catalytic, radical-removal, 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 a rare and precious metal. 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.

How do you pronounce 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 to 7.0. Continue stirring for 20-30 minutes until you get a nanoscale gold solution. This preparation method is advantageous because it is done at room temperatures, is simple to do, has gold nanoparticles that are 10-100nm and is small.

Applications of Gold Nanoparticles
The biochemical and physicochemical characteristics of gold nanoparticles allow them to play an important role in many aspects, such as immunoanalysis and biosensors. They can also be used for DNA recognition and detection. 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 daily necessities such as food and beverages 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. 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.
