It isn’t easy to diagnose wound infections before they’ve progressed into a nasty, purulent mess, and many doctors prefer to play it safe by doling out antibiotics early. But a clever new bandage that glows bright green at its first whiff of bad bacteria could help change that.
Led by chemistry professor Toby Jenkins at the University of Bath, the new “smart bandage”—although not yet tested in humans—might one day serve as an early warning system, allowing doctors and patients to detect infections before they get out of hand. The mechanism behind it is pretty clever: the bandage contains a gel-like material infused with tiny, fluorescent green dye-filled capsules. When it comes in contact with toxins produced by pathogenic bacteria, those capsules are punctured. And voila, a lovely green glow signals your unwanted microbial colonists.
