- Atomically dispersed Fe–N₄ sites anchored on N-doped porous carbon materials (Fe-SAs/NC) can mimic two antioxidative enzymes of catalase (CAT) and superoxide dismutase (SOD), and therefore serves as a bifunctional single-atom-based enzyme (SAzyme) for scavenging reactive oxygen species (ROS) to remove excess ROS generated during oxidative stress in cells.
