From the literature it is known that nanoparticles block the properties of oxygen transfer into a bacterial cell, which leads to its death.
Iroda Baxtiyor qizi Shermatova It's the silver ion (Ag+) that's the bactericide not the 'silver' nanoparticles. And the silver in air is not silver metal but in the fully oxidized state (Ag2O) on the surface (by XPS) and hence has some solubility in aqueous media. See for example: 'Silver colloids and invisible ink'
