U.K. scientists are using silicon-based "nanoprobes" to screen antibiotics that can latch onto the cell wall of drug-resistant bacteria, prompting them to weaken and break down. The technology was tested on vancomycin, an antibiotic that remains effective against infections such as methicillin-resistant Staphylococcus aureus. The work is part of efforts to find drugs to combat the spread of antibiotic-resistant superbugs at hospitals.
