Multi‐nanozyme that mimicking intracellular antioxidant defense system for cytoprotection. (A) Schematic for the synthesis of V₂O₅@pDA@MnO₂ and its process in mimicking intracellular antioxidant‐based defense system to remove ROS. (B) Element compositions analysis with TEM confirmed the formation of V₂O₅@pDA@MnO₂. (C) V₂O₅@pDA@MnO₂ exhibits a GPx‐like activity. (D) V₂O₅@pDA@MnO₂ exhibits a concentration‐dependent oxidize activity to NADPH. Adapted with permission.^{[ 237 ]} Copyright 2016, John Wiley & Sons
