"Silver Shield"
Bioactive compounds based on
nanosilver
Silver is known to mankind over 5000 years as a powerful natural
antibacterial agent. All known civilizations used silver for the treatment and
prevention of disease. Modern scientists proved that silver stimulates the
immune system, stabilize the body's metabolism and eliminates more than a
few hundred species of harmful bacteria and viruses (for comparison: the
spectrum of any chemical antibiotics - only 5-10 species).
- Deeply cleanses the skin, relieves inflammation;
- Stimulates metabolism and cell regeneration;
- Maintains the water-fat balance;
- Tones, refreshes and moisturizes the skin;
- Prevents allergic reactions;
- Stimulates the immune system, creates a protective barrier;
- Quickly heals wounds, prevents scarring;
- Carries acne prevention of diseases
Application:
In selected cream / mask / shampoo / conditioner / gel add
Colloidal Silver at a ratio of 1:3 (One part of the drug on the basis of
3 parts). Stir until smooth. Use in the conventional mode.
The drug can be used in initial concentration (no dilution basis) for applications on the
affected skin

Potential areas of application
• Conduct disinfection treatments in public places, including:
public transport (rail, subway), in health care and penititsiarnyh
institutions
at the sites of communal services, catering, sports complexes and
other places of mass attendance
• Creation of sanitary facilities of the new generation used: for
surface disinfection in premises, furniture, sanitary equipment,
medical products, linens, rugs and furs, agricultural premises
and products, water and other liquids
• Modification of traditional materials to make them active biocidal
properties: different kinds of packaging materials and packaging,
textiles and textile products, paints and other building materials,
paper and paperboard, bandages, plastics and film, ceramics and
glass, other materials and coatings .
Using
The drug is used as a functional additive in the process of further soaking clothes in the final stage wash
(after rinsing), and treatment of clothing and its problem areas method of irrigation products using domestic
cooking spray. The drug does not contain any chemical components, does not affect the color of the fabric
and can be used for all types of fabrics. Soaking garments in water with the addition of the drug can give
the product :
- Anti-microbial;
- Anti-virus;
- Anti odor;
- Allergenic;
- Antioxidant;
- Immunostimuliyuschimi properties of silver
with preservation of the effect of two weeks to several months.
Silver Clothing Until recently, clothing with miraculous properties of silver was considered the most
modern in terms of bactericidal protection and was available only to the richest and most influential people
of our planet.
Today, thanks to the unique products based on silver nanoparticles, everyone has an opportunity to make
their clothes SILVER and provide a powerful barrier to:
bacteria and viruses, odors and pathogens;
allergies;
stimuli;
free radicals (antioxidant).
Bactericidal effect of the solution has a prolonged
action and stored for up to 2-3 months.
The most common applications are:
• medical institutions, hospitals, motels and hotels;
• kindergartens, schools, sports facilities;
• residential buildings (bathrooms, kitchens, nurseries);
• offices, industrial premises;
• Places with high humidity (sauna dome, swimming pools,
basements, boiler);
• food establishments (warehouses, cold rooms,
workshops);
• agricultural enterprises (Stall, incubators, storage);
• crowded places (airports, train stations, subway,
subways);
• military barracks, etc.

The drug has bactericidal activity against Esherichia colli if it
contains a cluster of silver 40 mg / L and 20 mg / l and
bacteriostatic activity at 10 mg / liter.
Biological activity of silver nanoparticles was also confirmed for growth inhibition of vegetative and spore-forming
bacteria, increase seed germination and others, as there are appropriate protocols

From the analysis of the photo flat crystal structures that they could be formed from particles of atomic size (Ag). Not visible
texture on the flat faces. Clusters have a size distribution. So there must be visible to the texture of the crystal. Possibility of
controlled growth of nanostructures and nanobektov, is the most promising direction in this paper and the new technology will
have a strong demand from the groans of many branches of electronics, medicine, food, etc
