For nearly a century, we have waged a war on bacteria. We have learned to fight off these ‘enemies’ by using stronger and stronger weapons. As the bacteria have found ways to resist the lethal effects of one antimicrobial weapon, we have been forced to unleash another. There is now a real worry that we may be running out of options to tackle resistant bacteria. The medical community has been turning to nanosilver as an antimicrobial of last resort. Yet at the same time, many companies have seen a marketing advantage in including nano-silver as an ingredient in everyday products.
