Attacking Biofilm Formation

New research by mechanical engineers at Purdue University, West Lafayette, IN, aims at fighting bacterial biofilms that can foul implantable medical devices. Bacteria secrete a slimy substance that forms biofilms, allowing bacterial colonies to thrive on surfaces, including catheters, prosthetic valves, and other devices. Combating biofilms using antibiotics and toxic chemicals can lead to the growth of antibiotic-resistant strains.
