Colloidal gold is a colloid, or suspension of particles of gold in a liquid, usually color is normally either a deep red or a dirty goldish color, the latter being the color of the suspension of larger particles. While it has existed since ancient times, new appliions for this substance have great potential impact in many fields.
· A lateral flow immunochromatography strip test, based on antibody–gold nanoparticles specific for nervous necrosis virus (NNV), was developed for rapid, onsite detection of the virus in fish stocks. A monoclonal antibody against NNV was conjugated with colloidal gold as the detector antibody.
· The return of this coarse gold to the fine ore would make the sample necessary for assay or amalgamation as heavy as if the ore had not been thus crushed; and, consequently, this gold, once removed, is never again added; but a small sample of the finelycrushed and screened ore is assayed, and to the result the proportionate value of the coarse gold is added.

· Colloidal Gold. Evidence indies that gold nanoparticles (AuNPs) (of size less than 10 nanometeres), reduce DNA damage, enhance immune function and have antiinflammatory benefits, especially to the blood vascular system including atherosclerosis that occurs in diabetes. Accumulating evidence indies that AuNPs have received great attention ...
· Gold Number: The protective powers of different lyophilic sols are different which are measured in terms of "Gold Number". This term was introduced by Zsigmondy (1901).It is defined as "the minimum number of milligrams of a protective colloid which is required to just prevent the coagulation of 10 ml of a standard gold sol (containing to gm of gold per litre) by the addition of 1 ...
Introduction. Gold colloid is a suspension consisting of submicron gold nanoparticles suspended within a solvent, most often water. Gold nanoparticles have unique optical, electronic, and thermal properties and are being incorporated in a wide variety of technologies including microscopy, electronics, diagnostics, and therapeutics.. There are many important criteria that must be considered ...
Amalgamation Of Colloidal Gold Colloidal Gold was first prepared in a pure state in 1857 by the distinguished English chemist, Michael Faraday. Many uses were found for the amazing solutions of quotactivated In 1905, the German bacteriologist Robert Koch earned the Nobel Prize when he discovered gold cyanide inhibited growth of the bacillus that caused tuberculosis.
· Colloidal gold is a sol or colloidal suspension of nanoparticles of gold in a fluid, usually water. The colloid is usually either an intense red colour (for spherical particles less than 100 nm) or blue/purple (for larger spherical particles or nanorods).Due to their optical, electronic, and molecularrecognition properties, gold nanoparticles are the subject of substantial .
· Colloidal gold has antiinflammatory powers to alleviate pain and swelling among those with arthritis and bursitis. It has also shown promise for rejuvenating glandular systems to provide antiaging, higher IQ, and pineal gland enhancing possibilities. It has also been known to be effective for easing the pains and swellings of arthritis ...
· Colloidal gold particles with a mean diameter of nm were prepared according to the method of Frens [12]. An aqueous solution of chloroauric acid (100 ml % (W/V) AuCl 3 ·HCl·4H 2 O) was heated to boiling point, followed by adding 2 ml of % (W/V) sodium citrate solution.
· Fully inorganic, colloidal gold nanoclusters (NCs) constitute a new class of nanomaterials that are clearly distinguishable from their commonly studied metal–organic ligandcapped counterparts. As their synthesis by chemical methods is challenging, .

We present evidence that gold colloids form as a result of boiling, and that a fraction of the colloidal gold escapes deposition at the boiling horizon and continues to be transported with the rising fluids, explaining the high concentrations of gold in all of the chimney samples and suggesting that colloids may be an important transport mechanism for gold throughout aqueous oreforming systems.
