Synthesis and Application of Silver Nanoparticles (Ag NPs) for the Prevention of Infection in Healthcare Workers:  Silver is easily available and is known to have microbicidal effect; moreover, it does not impose any adverse effects on the human body. In addition to their bactericidal activity, small Ag NPs (<10 nm in diameter) can pass the B-B barrier, likely providing protection against brain damage.

Highest purity colloidal and ionic minerals 

What are colloids?

Colloids are trace elements that are dissolved as tiny particles in a liquid. The best known is probably the colloidal silver, but also colloidal gold, silicon and magnesium are becoming increasingly common.

The colloid contains precious metals such as gold or silver in its purest form. It contains not only electrically neutral particles, but also electrically charged ions. These are small particles that can be added to another substance. We encounter colloids – the small particles – every day and are often found in ointments or cosmetic products. Since the particles do not dissolve in a liquid, they can excel in the human body. This means that colloids such as silver and gold are suitable for a number of treatment and application areas. Many people no longer want to do without colloidal minerals in their travel and medicine cabinet.

Functions and benefits of colloidal minerals

What are the concentrations of colloidal minerals?

To the products

What functions and advantages do colloids offer?

Colloids were used centuries ago by our ancestors to detoxify the body with the tiny particles it contains. Silver in particular has long been known for its disinfectant properties and has always been used for various purposes. But other colloidal solutions also have properties that “help” the body in many ways.

Colloidal minerals can help the body build up bones, hair and skin, for example, and thereby enrich the body’s mineral balance.

What many people are not aware of is that the human body contains a large number of different precious metals, such as gold and silver. These precious metals are responsible, among other things, for the regeneration of damaged tissue. With colloids, such as gold or other precious metals, undersupply can be counteracted or prevented. 

To the products

 What are the concentrations of colloidal minerals?

With colloidal minerals such as gold, copper or silver, the concentration is measured in ppm. This abbreviation stands for parts per million. This term actually refers to the active ingredient content (gold, copper or silver) in one million parts of water. For colloidal minerals, this is the weight ratio between the mineral and the water in mg / kg. Since 1 liter of water weighs 1 kg, the specification of 25 ppm means, for example, that 25 milligrams of silver are suspended in 1 liter of water.

 Silver nanoparticles as a new generation of antimicrobials – ScienceDirect

Oligodynamic Effect of Silver Nanoparticles: a Review  Silver nanoparticles (AgNPs) over the last few years have gained immense reputation as the next-generation antibiotics owing to their broad-spectrum activity against the disease-causing microbes which has been also extended against the highly evolved MDR strains. Also known to support the synergistic effect in combination with various commercially used antibiotics, the potential of AgNPs could be extensively exploited to gradually replace the old-generation drugs that certainly have lost their tooth against the resistant microbes.

Silver Nanoparticles as Potential Antiviral Agents. Since metals may attack a broad range of targets in the virus there is a lower possibility to develop resistance as compared to conventional antivirals. The present review focuses on the development of methods for the production of silver nanoparticles and on their use as antiviral therapeutics against pathogenic viruses.
