What are colloidal metals?

in science •  4 years ago  (edited)

"Metallic nanoparticles are generally solid colloidal metal particles of size range 10–1000 nm that incorporates a therapeutic molecule which remains either dispersed in the matrix of polymer carrier, entrapped within a polymer shell, or attached or adsorbed by covalent linkage to the surface of the particles [236,237]."

"Colloidal nanoparticles are being intensely pursued in current nanoscience research. Nanochemists are often frustrated by the well-known fact that no two nanoparticles are the same, which precludes the deep understanding of many fundamental properties of colloidal nanoparticles in which the total structures (core plus surface) must be known."

"Electrical Disintegration: It is the combination of dispersion and condensation. This technique is most commonly used for the preparation of colloidal solutions of metals such as gold, silver, platinum, etc. It involves the use of two metal electrodes dipped in a dispersion medium. An electrical arc of intense heat is produced vaporizing some of the metal. The vapours condense to form precipitates which are of colloidal dimensions."

Silver rods can be replaced with, Zinc, Copper, ect to make their colloidal forms

"What you need:

Silver rods for electrodes – the silver must be pure, sterling silver is not good enough
Batteries (to generate around 27 – 30 volts) OR AC/DC electric charger rated at around 100 mA/h
Distilled (pure) water
Glass beaker or container – ideally borosilicate based

Method:

This is done ideally in the dark and in colder temperatures (around 39 F – 50 F). Place the silver rods into the beaker of distilled water. Connect the batteries together in a series and attach the remaining unconnected terminals to each silver rod.

It takes about 10-15 minutes before anything happens. Then you’ll see a yellowish smoky mist appear. It takes around 30 minutes for the reaction to complete."

"Concentration of colloidal silver is measured in parts per million and ranges from 10 parts per million up to more than 1000 parts per million.

If you intend to learn how to make your own colloidal silver generator, it is absolutely critical to know the concentration level of your final result. It is also vital to know the concentration level (in parts per million) of any colloidal solution you use.

You cannot accurately monitor your risk for metal poisoning and other serious side effects that can occur if you don’t KNOW the concentration of your colloidal silver. If you are making your own colloidal silver solution, you can purchase a TDS 3 meter which will indicate the concentration of silver particles in the final solution."
