University of Wisconsin-Madison -- Using an advanced form of a rubber stamp, researchers have developed a way to adhere an ultra-thin antibacterial coating to a wound. The active ingredient, silver, "has been used to prevent and treat infections for ages," says first author Ankit Agarwal, a postdoctoral fellow in chemical and biological engineering at the University of Wisconsin-Madison. "But silver can also kill skin cells, and therefore we need to develop materials that deliver antibacterial but nontoxic levels of silver to wounds."
