Researchers use buckyballs to reinvent 'antibiotic of last resort'

Chemists hope a new variant of vancomycin that contains buckyballs — tiny cage-shaped molecules of pure carbon — could become the world’s first targeted antibiotic, creating a new line of defense against bioweapons like anthrax. Vancomycin, which entered clinical service 40 years ago, is the antibiotic of last resort, given only when all others fail. Unfortunately, vancomycin-resistant strains of bacteria have appeared in recent years.
