In principle, that is true.
The antibacterial effect of silver nanoparticles is known. This is the reason why it is used as a coating for implants or in wound dressings. The effect is based on the release of silver ions, i.e. small, electrically charged particulate matter. Silver nanoparticles have especially good properties, as they have a large surface from which these ions can be released. Scientific studies show that besides the antibacterial effect these ions act as antiviral agents as well. Laboratory tests have shown that they are effective against certain types of corona virus family. Scientists are currently investigating whether this applies to the originator of the disease COVID-19 and are looking into the use of surface coatings with silver nanoparticles in hospitals and public places.
