Wound dressing releases silver nanoparticles when infections occur

Although silver is highly effective at killing bacteria, it can also be toxic to humans in large amounts. That’s where a new wound dressing is intended to come in, as it only releases its silver payload when infections are present.

Currently being developed at the University of South Australia, the dressing is intended mainly for use on children with burn injuries, as they are particularly at risk of serious infections and sepsis. It’s made up of a topically applied hydrogel that contains silver nanoparticles along with proprietary ingredients which are sensitive to changes in pH and temperature … read more
