What is the difference between your NanoSilver Solution and Ionic Silver and Collodial Silver?

N-Shield's NanoSilver Solution contains pure physical silver nanoparticles (average 5nm) that are attached to the water molecules and is dispersed evenly in water and appears as a clear solution as good as pure water.  It is also known as SilverSol in the industry term.

Whereas Colloidal Silver is ultra small silver particles processed to suspend in water and the particle size is generally much bigger in the range of 100nm upwards.  Due to the way it is processed, the solution can also contain chemical impurities and other toxic heavy metals.
In the case of Ionic Silver solutions they generally do not contain pure silver particles but compounds of silver such as Silver Chloride or Silver nitrate/nitride and these are stabilized (i.e. suspended) in water with the help of some reagents or compounds.

Is Nanosilver Safe (to use)?

We often get this question from potential users.

It is a fact that over the thousands of years of human usage of silver/nanosilver there has never been a single report of significant incidents.** (Whereas it is reported that Anaphylactic reaction to penicillin usage cause 400 to 800 deaths annually among Americans alone.)

Did You Know : Silver was in widespread used for antibacterial, treating and healing of wounds until 1938?

It was replaced by penicillin, a man-made antibiotic and silver's usage eventually dwindled as more and more cheaper chemical based antobiotic were being created by the big pharmaceutical companies.

Did You Know : that Silver salt was applied on the eyes of every newborn in hospitals in the early days?

Silver nitrate was applied on the eyes of every newborn in the early days to prevent neonatal conjunctivitis (gonorrheal ophthalmia), a "pink eye" disease that could lead to blindness.  It was subsequently replaced by man-made chemical antibiotics.

Did You Know : "Born with a Silver spoon in his mouth" - How this came about?

In the middle ages there was a plague in Europe and the wealthy families would gave their children silver spoon to suck on to prevent them from contracting the plague (since it was known that silver is an effective antimicrobial agent).

Did You Know : that Nanoslver is approved to be used in swimming pool?

Nanosilver is approved by the US FIFRA for use as an algaecide in swimming pool since 1954.

There are some dark grey spots on my bottle of Nanosilver Solution. What might that be?

The dark grey stains that you see is most likely the silver nano particles residue that was left after the water has evaporated. Nano Silver powder in fact is dark grey in appearance.  It is normal and you can simply wipe it off with a damp cloth.

Does Nanosilver actually kills dust mites?

Nanosilver is non toxic and it does not actually kill the dust mites directly. House dust mites eat a special fungus that can survive the mite's toxic gut. The fungi then emerge from mite's dropping to grow again. The fungi may be helpful to the mite by breaking down food.

Nanosilver will destroy the fungi that dust mites rely on to survive and by so doing will exterminate the dust mite indirectly. This also applies to other pests such as cockroaches where they depended on other pathogen in their guts to help them breakdown their food.  So basically Nanosilver will anniliate these pests by destroying their ecosystem.

Does Nanosilver kills cockcroaches?

It has been reported by users that Nanosilver can help to repell cockroaches. The roaches did not appear again after the users sprayed it on those places where the roaches used to be found.  The reason is similar to the case with dust mites where the Nanosilver will kills the bacteria that lives in the guts of the roaches when come into contact.  As such the roaches will avoid the areas laced with Nanosilver.
