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.

In an innovation that may ultimately help to prevent deadly bloodstream infections, a team of biomedical engineers and infectious disease specialists at Brown University developed a coating to keep intravascular catheters from becoming a haven for harmful bacteria.
