There are studies confirming the antiviral effect of nanocolloidal silver against viruses that cause serious respiratory infections (influenza, parainfluenza, adenovirus, respiratory syncytial virus, and other viruses with protein structures in their envelope).
What is the basis for this effect?
To understand this mechanism, let us recall the properties of a magnet. Try bringing two magnets close to each other. Only opposite poles will come into contact and stick together, while like poles will repel each other.
A similar effect occurs when a virus comes into contact with a silver particle. The surface of a silver nanoparticle is positively charged and "sticks" to negatively charged areas on the surface of the viral particle. As a result, the virus, surrounded by nanocolloidal particles, is blocked and cannot enter the cell. By the same principle, silver binds to the DNA or RNA molecules of the virus, preventing the pathogen from multiplying.
Researchers have noted that for silver to destroy viruses, the particles must be of a specific, ultra-small size, comparable to the size of the virus. It is precisely this size (3–100 nm) that the nanoparticles in the Argentokea Nanolar and Argentokea Newsept sprays have.
Therefore, the preventive use of Argentokea sprays will help avoid infection during the ARVI season, or reduce the severity of the infection by weakening the attack of the pathogen.
