Infections on implantsJoint replacements, pacemakers and catheters are prone to biofilms, bacterial sheets that can cause hard-to-treat, antibiotic-resistant infections. A University of Michigan Engineering team built an implantable platform, DARTS (dynamically actuated reconfigurable topographical surface), that reduced bacterial burden and improved tissue response in mice, according to the university's October 27 news release. The study appeared in Advanced Functional Materials.Two mechanisms...
