For burn victims, guarding wounds against infection is critical but wrapping wound dressings around fingers and toes can be tricky. Scientists have reporting the development of novel, ultrathin coatings - nanosheets - that can cling to the body's most difficult-to-protect contours and keep bacteria at bay.
Yosuke Okamura, Ph.D., explains that existing wound dressings work well when it comes to treating burns on relatively flat and broad areas. But the human body has curves, wrinkles and ridges that present problems for these dressings. So Okamura's team developed a novel biomaterial out of tiny pieces of nanosheets that are super-flexible and sticky and they have tested them successfully on mice.
