An incredible new study has demonstrated the potential of a wound dressing that can fight bacterial infections using a weak electrical field. Offering a novel way to battle antibiotic resistant infections, the dressing has been approved by the FDA and is currently being tested in human burn patients.
The National Institutes of Health estimates up to 80 percent of all bacterial infections are caused by a phenotype known as a bacterial biofilm. These biofilms occur when bacterial cells adhere together to form a slimy substance, often around wounds or implanted medical devices. Bacterial biofilms can be difficult to eradicate at the best of times, a task made even more challenging with the rise of antibiotic-resistant bacteria.
