Nanosilver is not a 'silver bullet' in long-term treatment of infections

Nanosilver is a potent antimicrobial that is currently used in medical devices such as internal catheters, as well as wound dressings, in particular for burn wounds, to fight or prevent infections. The scientific evidence that bacteria can adapt to nanoparticles means we need effective regulation of the use of nanoparticles, with clear risks versus benefits assessment and clear antimicrobial targets.
