New Bacteria-Resistant Materials May Reduce Hospital Infections
On August 12, researchers at the University of Nottingham, U.K., announced that they have discovered a new class of polymers that are resistant to bacterial attachment. The new materials could lead to a reduction in hospital infections and medical-device failures.
Medical device-associated infections can lead to systemic infections or device failure, the researchers said. When affecting commonly used devices, such as urinary and venous catheters, bacteria form communities known as biofilms. This “strength in numbers approach” protects them against the bodies’ natural defenses and antibiotics.
Scientists at the University’s Schools of Pharmacy and Molecular Medical Sciences have shown that when the new materials are applied to the surface of medical devices, they repel bacteria and prevent them from forming biofilms.
