Not quite. Kodak has patents on silver nanoparticles for antibacterial applications. I did quite a bit of the electron microscopy to support those patents.

It sounds like you are the man to tell us whether silver nanoparticles do perform antibacterial functions and, perhaps, whether they perform similarly against viral and fungal infections. I know that in the days of film photography, silver was used to develop pictures from camera film. It appears that somewhere in there may be a story about how Kodak stumbled onto the antibacterial qualities of silver while using it in their film developing industry.
