A nano-gold solution

Made from high-purity raw gold. Gold is reduced to a particle size less than 15nm using a new processing technique. This improves gold’s inherent properties such as its catalytic, radical-removal, and dispersion effects.

Physical Index

Indicator name: AuS-WM1000

Appearance: purple liquid

Solid content: >=1000ppm

PH: 7.0+-0.5

Particle size: >=15nm

Density: 1.01g/ml

Gold purity: 99.9999%

Preparation method

Prepare a PVP Solution with a Concentration of 1.01×10-4 Mol/L. A HAuCl4*4H2O with a Concentration of 2.44×10-3 Mol/L is also available. Add 80 mL tridistilled water, 10 mL the chloroauric acids solution, or 10 mL the no-protection agent solution to the beaker. Place the beaker in the digital speed constant temperature magnetic stirring machine, set the speed to 600 r/min and stir. After heating the solution to 75°C, maintain the temperature for two minutes. Add a volume of the reducing agents (Na3C6H5O7 and NaBH4) to the above mixture, immediately add the solution to it, begin timing and keep the liquid colour constant.

Development History

Paracelsus was an outstanding physician and pharmacist in the 16th Century who prepared “drinking Gold” for mental illnesses.

Nano gold solution

Science has been on stage. In 1857 when British scientist Faraday examined Dalton’s theory he used gold cyanide to reduce a gold solution. After adding a small quantity of electrolyte the solution turned from ruby red to blue before agglomerating to nothing. The addition of gelatin, or any macromolecular substance can stop this process. The reason for his discovery was not known, but it laid the foundations of the application of Nano-gold. In 1885, Nano-gold solutions were used in the United States to treat alcoholism. Dr. Koch also discovered in 1890 that Mycobacterium tuberculosis couldn’t survive on the gold surface. Nano-golds were used in 1890 to treat arthritis. Discovered that Nano-gold can relieve pain in patients and strengthen their bodies. Kausche & Ruska, in 1939, used an electron microscopy to observe the tobacco virus, labeled by gold particles. These particles had a very high electron density. Faulk and Taylor pioneered the use of Nano-gold labeling in 1971 by using immunogold staining to combine anti-Salmonella rabbit serum with Nano gold particles.
