Researchers create electric field-based dressings to heal wound infections

Researchers at Indiana University School of Medicine found a way of using electricity to boost the fight against bacterial infection.

Chandan Sen, PhD, and Sashwati R., Ph.D., conducted research in the Indiana Center for Regenerative Medicine and Engineering. Their work led to the creation of a dressing which uses an electric field for the disruption of biofilm infections. The findings of the study were published recently in Annals of Surgery, a high-impact journal.

Biofilms of bacteria are slimy, thin films that can form on wounds such as burns, post-surgical infections or after medical devices, like catheters, have been placed inside the body. The bacteria use their electric fields to communicate, and to form biofilms. This makes them more aggressive and difficult to treat. The Centers for Disease Control and Prevention estimate that 65 percent of infections are caused bacteria with a biofilm phenotype. However, the National Institutes of Health believe this number to be closer to 80 percent.
