Nanocrystalline silver products

It has been suggested that some nanocrystalline silver products release a cluster of silver ions and radicals, which are highly antibacterial because of unpaired electrons in outer orbitals. Silver and silver radicals released from these products are reported to act by impairing electron transport, inactivating bacterial DNA, cell membrane damage, and binding and precipitation of insoluble complexes. ...
