Water contaminated with bacteria is a large threat to global health. A Chinese research team has described a simple new method of disinfection in the journal Angewandte Chemie that is based on tiny biocompatible assemblies of atoms, known as quantum dots, made of silver sulfide with caps made of a silver-binding peptide. When irradiated with near-infrared light, they kill bacteria in water with high efficiency through synergistic effects.
