Like a protective tent over a colony of harmful bacteria, biofilms make the treatment of skin infections especially difficult. Microorganisms protected in a biofilm pose a significant health risk due to their antibiotic resistance and recalcitrance to treatment, and biofilm-protected bacteria account for some 80 percent of total bacterial infections in humans and are 50 to 1,000 times more resistant to antibiotics than simpler bacterial infections.
“In essence, we may have stumbled onto a magic bullet,” said David Fox, a Los Alamos National Laboratory researcher on the project. “Through a robust screening strategy, our research team has identified a unique class of materials, known as ionic liquids, which both neutralize biofilm-forming pathogens and deliver drugs through the skin,” he said.
