Nanosilver compared with Microsilver

Microsilver is well tolerated by the skin

Microsilver refers to silver particles of about 10 micrometres, i.e. about 0.01 millimetres. One gram of microsilver already results in a surface area of 5 square metres. In contrast to the small nanoparticles in nanosilver under discussion, these cannot pass through the skin, i.e. their effects only take place on the surface of the skin, they do not enter the body and do not accumulate.
Because the small microparticles can reduce the germ load and do not scratch the skin, clothing and care products with microsilver can be recommended for irritated, inflamed skin and even for neurodermatitis.


SURFACE PROTECTION with LONG-TERM EFFECT and VALUE PROTECTION is characterised by a homogeneous, pore-free SURFACE.
We achieve this through a unique uniform GRAIN SIZE DISTRIBUTION, called matrix in technical language, of the micro raw material paticles. No oversized grains, so no bacteria, virus nests or fungal particles can form in between. Simply spray or apply, or also as a cold nebulisation.

With nano-microsilver colloidal elemental silver in solid form

What exactly is colloidal silver?

Before applying colloidal silver externally or taking it, it is useful to know what it is. This is especially important because there is always confusion and misunderstanding about the terms. This may also be due to the fact that colloid chemistry is a very complex field and the term colloid has changed over time. Therefore, it should be stated in advance what colloidal silver is not in the sense of this book: colloidal silver is not a silver salt or any other silver compound, even if this is unfortunately repeatedly claimed.
If the following explanations are too detailed for you, you can of course skip the chapter, but you should definitely remember that colloidal silver is always equated with elemental silver here.

From a scientific point of view, colloidal silver is a liquid dispersion of elemental silver or a liquid dispersion of hardly soluble silver compounds. For health applications, as described in this book, only the first variant, elemental silver, may be used.

The term dispersion in turn covers many different systems. A mixture of at least two substances that are not or hardly soluble in each other and that do not form a chemical compound with each other is called a dispersion. Most dispersions are in turn colloids. In them, one substance, the dispersed phase (for example elemental silver) is very finely distributed in a second substance, the dispersant (for example distilled water). Depending on which phases are present, one speaks, for example, of emulsions (liquid-liquid as in milk), foams (liquid-gaseous as in soap foam) or aerosols (gaseous-liquid as in mist or gaseous-solid as in smoke).

Suspensions, on the other hand, are present when, as with colloidal silver, the smallest particles of a solid (elemental silver) are finely distributed in a liquid (distilled water).

Depending on the particle size of the substance distributed in the dispersion medium, a distinction is made between molecular dispersions (smaller than 1 nanometre), colloidal dispersions (1 nanometre to 1 micrometre) or coarse dispersions (larger than 1 micrometre). Colloidal silver falls into the second group.

With salts, the situation is completely different. For example, if you add table salt (sodium chloride) to water, the salt immediately dissolves into positively charged cations (Na+) and negatively charged anions (Cl-). This means that the sodium ions have one electron less than they "deserve" and the chloride ions have one electron too many. If there are other cations and anions in the water, then other salts can form, possibly even heavy metal salts. In pure distilled water (H2O) there are no such impurities. In terms of ions, there are only a few protons (H+ = hydrogen atoms that are missing an electron) and hydroxyl ions (OH-) with an excess electron.

The same happens with silver when individual positively charged silver ions (Ag+) detach themselves from the elementary compound. As long as we work with distilled water, nothing dramatic happens. In such a system, "the silver world is still in order". But woe betide us if there are impurities (even a single grain of common salt is enough) in the water used to produce colloidal silver. Then possibly dangerous silver salts are produced instead of health-promoting colloidal silver.

As already mentioned, the difference between salts and suspensions is often ignored, and silver salts or even silver protein compounds are also lumped together with elemental colloidal silver. Unfortunately, even experts regarded as authorities do this. Therefore, one should not be surprised when false reports appear in the media again and again. However, it should be emphasised that the dubious suppliers of alleged colloidal silver, who on top of that advertise their products as a panacea, bear a large share of the blame for the fact that a tried and tested remedy is repeatedly and unjustly discredited.

We are talking here about colloidal silver, such as arseptum Longtime, which contains as much elemental silver as possible, but in no way about silver salts or other silver compounds.

What is nanosilver?

Nanosilver is the smallest, elemental silver particles that are smaller than 100 nanometres. Particles of this kind are already used in wound dressings and plasters, cosmetics or dermatics for skin diseases or in special functional clothing. The silver ions remain on the skin surface: they are not absorbed and form an ion film on the skin. This is supposed to destroy the cell structure of the bacteria, which is made up of proteins, and hinder their metabolism. This is supposed to prevent the spreading and stop the growth of germs. Nano-particles are supposed to work better than micro-silver particles because of their small size. However, they are so small that they are suspected of being absorbed by the body. In the process, they could potentially damage cells and other protein structures and cause as yet unforeseeable consequential damage.

Nanosilver is fundamentally different from other forms of silver

Nanosilver refers to particles of elemental silver less than 100 nanometres in size. The average particle size is about 50 nanometres, or 0.00005 millimetres. One gram of nanosilver has a surface area of about 500 square metres. The division into very many small particles therefore enormously increases the effective surfaces, and therefore many more reactive silver ions can be created than with larger silver particles.
The tiny silver nanoparticles can even penetrate cell membranes. Inside the cell, they act like a depot from which silver ions are continuously released over a longer period of time.
Nanosilver – also known as colloidal silver – shows high toxicity even at relatively low silver concentrations due to its large surface distribution. There are still no conclusive study results on the possible long-term effects of nanosilver enriched in the body, which is why its use is considered very critical.
