Colloidal gold is a suspension (or colloid) of sub~micrometre sized particles of gold in purified water. The liquid is usually either an intense red colour (for particles less than 100 nm), or a dirty yellowish colour (for larger particles). Due to the unique optical, electronic, and molecular~recognition properties of gold nanoparticles, they are the subject of substantial research, with applications in a wide variety of areas, including electron microscopy, electronics, nanotechnology, and materials science.
Known since ancient times, the synthesis of colloidal gold was originally used as a method of staining glass. Modern scientific evaluation of colloidal gold did not begin until Michael Faraday's work of the 1850s. An "Elixir of Life", a potion made from gold, was discussed, if not actually manufactured, in ancient times. In the 16th century, the alchemist Paracelsus claimed to have created a potion called Aurum Potabile (Latin: potable gold). Paracelsus' work is known to have inspired Michael Faraday to prepare the first pure sample of colloidal gold, which he called 'activated gold', in 1857.
For a long time the composition of the Cassius ruby-gold was unclear. Faraday was the first to recognize that the colour was due to the minute size of the gold particles. In 1898 Richard Adolf Zsigmondy prepared the first colloidal gold in diluted solution. Apart from Zsigmondy, Theodor Svedberg, who invented ultracentrifugation, and Gustav Mie, who provided the theory for scattering and absorption by spherical particles, were also interested in understanding synthesis and properties of colloidal gold.
COLLOIDAL GOLD - 40ppm
Herbs of Avalon's Colloidal Gold is 40 ppm of 0.999 pure gold as bioavailable microparticles colloidally suspended in pure pharmaceutical grade water.
Do not allow to freeze as all of the gold microparticles will no longer be colloidally suspended. After the frozen product thaws, the liquid will turn clear.
