Can bacteria adapt to nano-silver?


Researchers from UNSW have cautioned that more work is needed to understand how micro-organisms respond to the disinfecting properties of silver nano-particles, increasingly used in consumer goods, and for medical and environmental applications.

However, antimicrobial action of nanosilver is not universal Furthermore, according to a new study, overexposure to silver nano-particles can cause potentially harmful organisms to rapidly adapt and flourish.
