What is the role of Colloidal Gold? Colloidal Gold is safe and reliable, has stable performance, and has bright colour is a non-toxic and tasteless transparent solution and can be widely used for biological colouring, DNA analysis, Industrial catalysis, CO gas removal and other fields. Various solvent-type nano-gold solutions can also be produced as needed. Gold with high purity is edible. Nanogold solution uses 99.99% gold as a raw material; after a very scientific and rigorous preparation process production of nano gold water solution is non-toxic, tasteless, Safe, reliable, and purple-red solution appearance, up to edible grade. Nanoscale gold particles have a good catalytic function and the function of removing free radicals in the human body. The nano-gold solution has a strong antioxidant force, which can promote metabolism. Strong corrosion resistance, friction resistance, anti-corrosion performance, and no allergy to any skin phenomenon. It can be used in food, glass, biological colouring agent, genetic material identification, refining of environmental purification products, food, cosmetics preservatives, and added to cosmetics to play a role of whitening, anti-ageing, and moisturizing. It can also produce antibacterial and anti-inflammatory drugs, medical equipment, health products, and beauty care equipment. Production of all kinds of daily necessities, food, drinks and other life closely related to people's life. Such as nano gold soap, toothbrushes, and beauty masks.
What is nano-gold? Nanogold is an elemental gold with a diameter between 1 and 100 nm. It has high electron density, dielectric properties and catalysis. Nanogold is generally prepared with chlorine acid, which can be easily prepared into different particle size sizes, and the colour will change with the diameter size. Nanoscale metal in gold is an elemental gold, the tiny particles of gold between 1 and 100 nm in diameter. This gold has high electron density, dielectric properties and catalytic action, can bind to various biomacromolecules, and does not affect biological activity. The difference between nano-gold and ordinary gold lies in that: first, the colour is different. Different colour is one of the main differences between nano gold and gold. The colour of nano gold varies with the size, while the colour of gold is a single golden yellow with a metallic lustre. In addition, the properties of nanometer gold and gold are also different. Nanosized gold has high electron density, dielectric characteristics, catalytic effect, biological properties and rich physical and chemical properties. And ordinary gold has good physical and chemical characteristics, stable properties, and strong corrosion resistance. The shape of gold is also different between nano-gold and gold. Nanogold refers to the tiny particles of gold with a diameter of 1~100nm. Under a high-power microscope, you can see it in grain, flower, and square shapes. And gold is a precious metal with good ductility, which can be used as gold nuggets, gold ingot, gold powder, gold jewellery, etc.
What are the influencing factors that affect the colour of the nano-gold solution? Nanog solution, namely nano guy with different particle sizes, shows different colours. The colour of the nanometer gold solution is related to many factors. The small size nano gold (2-5nm star is yellow, the medium size nanometer gold (10-20nm) is wine red, and the larger nano gold (30-80nm star is purplish red. Nano-gold particles below a particle size of 12nm are dispersed into the aqueous solution, forming a neutral solution with stable and uniform colour. The colour of the solution is not golden yellow but red. The solution becomes green if other substances are added to form the condensed state.
The price of Colloidal Gold The different price of Colloidal Goldpurity is also different. The market price of Colloidal Gold is in the process of dynamic change. If you need it, you can ask us at any time.
