Another question I am getting asked frequently is about Colloidal Gold and if it has health benefits like Colloidal Silver. Well, the answer is no; however, I will explain further as to why Colloidal Gold has not got health benefits.

Due to the unique optical, electronic and molecular properties of gold nano-particles; they are the subject of substantial research, with applications in a wide variety of areas. These include electron microscopy, electronics, nanotechnology, and material 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. Colloidal gold has been used to colour glass; giving intense shades of yellow, red or mauve; depending on the concentration of gold, and in Hindu-Chemistry, for various potions. In the 16th century, the alchemist Paracelsus claimed to have created a potion called Aurum Potable which is Latin for potable gold.

In the 17th century, the glass colouring process was refined by Andreus Cassius and Johann Kunckel. In 1842, John Herschel invented a photographic process called Chrysotype [from the Greek word for gold] that used Colloidal Gold to record images on paper. Paracelsus’ work; known to have inspired Faraday to prepare the first pure sample of colloidal gold, which he called activated gold, in 1857.

Health and medical applications

Experimental medication for Alzheimer’s disease

An in-vitro experiment has shown that the combination of microwave radiation and Colloidal Gold can destroy the beta-amyloid fibrils and plaque which are associated with Alzheimer’s disease. The possibilities for numerous similar radiative applications are also currently under exploration with Colloidal Gold in the UK, USA and Europe.

Drug carrier

Gold nanoparticles are being tested as carriers for drugs such as Paclitaxel. The administration of hydrophobic drugs require molecular encapsulation; it is found that nano-sized particles are particularly efficient in evading the reticuloendothelial system.

Tumour detection

In cancer research, Colloidal Gold can be used to target tumours and provide detection using SERS [Surface Enhanced Raman Spectroscopy] in vivo. These gold nanoparticles are surrounded by Raman reporters which provide light emission that is over 200 times brighter than quantum dots. It was found that the Raman reporters; stabilized when the nanoparticles were encapsulated with a thiol-modified polyethene glycol coat. This allows for compatibility and/or circulation. Specifically, to target tumour cells, the pegylated gold particles are conjugated with an antibody such as scFv; against for example the epidermal growth factor receptor, which is sometimes over-expressed in cells of certain cancer types. Using SERS, these pegylated gold nanoparticles can then detect the location of the tumour.

So whilst we hope you see that Colloidal Gold has its uses it is not the same or better than Colloidal Silver and only has very specific roles.

We are still of the opinion that Colloidal Silver, Ionic Silver, Nano-Silver, MesoSilver, Nano-particle Colloidal Silver, Colloidal Silver Spray are the only true example of an all-round natural antibiotic which is perfect for treating health issues at home.
