A nano-gold solution

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

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

The concentrations of the HAuCl4*4H2O, Na3C6H5O7*2H2O, PVP and NaBH4 solutions are all different. 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 reducing agents (Na3C6H5O7 and NaBH4) to the above mixture, immediately add the reducing agents, 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 illness treatment.

Nano gold solution

Science has been the center of attention. When British scientist Faraday, who was studying Dalton’s theory in 1857 used gold chloride, to reduce a gold-nanoparticle solution, he found that when a small amount electrolyte was added, the solution turned from a ruby colour to a blue color, and eventually agglomerated. 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 the Nano-gold Solution was frequently used as the primary ingredient in treating alcoholism in America. In 1890 Dr. Koch discovered Mycobacterium Tuberculosis cannot survive on the surface gold. 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.
