Ceroxid‐Zirconiumoxid‐Nanopartikel von 2 nm Größe und mit erhöhtem Ce3+‐Gehalt zeigen eine stark erhöhte Fähigkeit zum Abfangen reaktiver Sauerstoffspezies (ROS). S.‐H. Lee, T. Hyeon et al. beschreiben in der Zuschrift auf S. 11557 die überlegenen Eigenschaften von Ce0.7Zr0.3O2‐Nanopartikeln bei der Regulation von Entzündungszellen. Sie wirken als effiziente ROS‐Fänger gegen Multiorganversagen bei...
The two oxidation states of ceria nanoparticles, Ce3+ and Ce4+, play a pivotal role in scavenging reactive oxygen species (ROS). In particular, Ce3+ is largely responsible for removing O2− and .OH that are associated with inflammatory response and cell death. The synthesis is reported of 2 nm ceria–zirconia nanoparticles (CZ NPs) that possess a higher Ce3+/Ce4+ ratio and faster conversion from Ce4+...
