Electric bandage zaps biofilm infections.

The article reports that researcher Chandan K. Sen and others at Ohio State University Wexner Medical Center has developed a textile-based electric bandage that fights infections physically instead of chemically, thwarting the bacteria's ability to develop resistance. It mentions dressing is patterned with silver and zinc polka dots that create a weak electric field which disrupts the electrical signals that bacteria send to one another to form biofilms.
