Comparative toxicity of bimetallic Fe nanoparticles toward Escherichia coli: mechanism and environmental implications†
Abstract
Herein, we assessed the potential toxicities of different bimetallic Fe nanoparticles (Fe/Pd, Fe/Cu, Fe/Ni, and Fe/Pt) toward E. coli and compared them with that of unmodified Fe. The results showed that Fe/Cu was the most toxic followed by Fe, Fe/Ni, Fe/Pt, and Fe/Pd nanoparticles in descending order.
