Slaying bacteria with their own weapons

A novel antibiotic delivery system would exploit small molecules called siderophores that bacteria secrete to scavenge for iron in their environments. Each bacterium has its own system of siderophores, which it pumps across its cell membrane before releasing the iron the siderophores hold. If an antibiotic were linked to one of these scavenger molecules, it would be converted into a tiny Trojan horse that would smuggle antibiotics inside a bacterium’s cell membrane.
