CeO2/Mn3O4 Nanocrystals: Epitaxially Strained CeO2/Mn3O4 Nanocrystals as an Enhanced Antioxidant for Radioprotection (Adv. Mater. 31/2020)

Tuning the surface strain of inorganic nanozymes can enhance catalytic reactivity to scavenge reactive oxygen species (ROS). In article number 2001566, Kyungpyo Park, Taeghwan Hyeon, and co-workers present epitaxially strained CeO2/Mn3O4 nanocrystals as a highly catalytic antioxidant that can protect tissue-resident stem cells from ionizing-radiation-induced ROS damage.
