Using state-of-the-art technology scientists at The Univ. of Nottinghamhave discovered a new class of polymers that are resistant to bacterial attachment. These new materials could lead to a significant reduction in hospital infections and medical device failures.
Medical device associated infections can lead to systemic infections or device failure, costing the British NHS £1b a year. Affecting many commonly used devices including urinary and venous catheters — bacteria form communities known as biofilms. This “strength in numbers approach” protects them against the bodies’ natural defenses and antibiotics.
Experts in the 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 forming biofilms.
