Rice University scientists have developed halide perovskite nanocrystals that have shown potential as antimicrobial agents that are stable, effective, and easy to produce. The scientists developed a method that coated the halide perovskite nanocrystals in two layers of silicon dioxide. Next, they tested the antimicrobial properties and durability of the double-coated halide perovskite nanocrystals and showed that under relatively low levels of visible light, the halide perovskite nanocrystals destroyed more than 90% of E. coli bacteria in a solution after six hours.
