Cleaner Coating (IMAGE) Brown University Caption Brown University researchers have developed a coating for intravascular catheters that kills bacteria and keeps them from forming hard-to-eliminate biofilms. The coated catheters on the right show no signs of bacteria build-up in bioluminescence imaging, whereas uncoated catheters or catheters coated with a more traditional antibiotic show signs of bacterial colonization. The researchers are hopeful that the coating could one day be translated to clinical settings, where it could help to reduce catheter-related bloodstream infections.
