Novel Antibacterial Coatings for Combating Healthcare-Associated Infections

Brown University, 2010 - $18,200

Ventilator-associated pneumonia (VAP) is the second most common type of healthcare-associated infection in the US. VAP occurs when bacteria form on endotracheal tubes and invade the lungs, resulting in over $10 billion in unnecessary hospital expenses and almost 36,000 deaths annually.

Currently, only two methods are used to combat VAP: sterilization and antibiotics. Sterilizing medical tubes rids the surface of transmissible pathogenic agents, but over half of all endotracheal tubes are exposed to bacteria even before being inserted, with some adhering irreversibly to the tube surface. The second technique is administering antibiotics to patients, but this has not shown satisfactory results due to bacteria’s inherent resistance to antibiotics.

This team is developing nano-TEC, a proprietary antibacterial coating that is effective in preventing bacteria formation on endotracheal tubes. In bench tests their solution is six times more effective and costs substantially less than the only other antibacterial coating products on the market.
