Elder of ZiyonDespite advances in treatment regimens and the best efforts of nurses and doctors, about 70% of all people with severe burns die from related infections. But a revolutionary new wound dressing developed at Tel Aviv University could cut that number dramatically.
Prof. Meital Zilberman of TAU's Department of Biomedical Engineering has developed a new wound dressing based on fibers she engineered -- fibers that can be loaded with drugs like antibiotics to speed up the healing process, and then dissolve when they've done their job. A study published in the Journal of Biomedical Materials Research -- Applied Biomaterials demonstrates that, after only two days, this dressing can eradicate infection-causing bacteria.
The new dressing protects the wound until it is no longer needed, after which it melts away. "We've developed the first wound dressing that both releases antibiotic drugs and biodegrades in a controlled manner," says Prof. Zilberman. "It solves current mechanical and physical limitations in wound-dressing techniques and gives physicians a new and more effective platform for treating burns and bedsores."
