Silver nanoparticles are a real thing AgNP it uses a phenomena called plasmon polariton excitation at the surface of metallaic material - I'm not making this shit up I swear I think its possible to use these AgNP to fight the Chinese virus.
The NIH has a 2011 article on silver nano-particles and their possible effectiveness against viruses. Nothing on coronavirus however. There hasn’t been enough testing but it may hold promise:

Casting about for a miracle cure probably won’t be terribly helpful. There may even be some, like I said two weeks ago, that have an effect on mild cases. Certainly rinsing your hands with silver in solution would probably be effective at cleansing your hands. The body isn’t just a bag of water.
Searching for a “cure” on the shelves at PetSmart is panic behavior.
“any thoughts”
my only thought is that it’s well known that certain formulations of silver used externally can be useful in medicine, for example, silver nitrate solution used as eye-drops in newborns ... however, everything i’ve read from credible sources claim that silver formulations consumed internally are a hoax and a fraud and that if the doses are high enough, even dangerous ...
