Fe–N/C single-atom catalysts exhibiting multienzyme activity and ROS scavenging ability in cells

Abstract

Fe–N/C single atom catalysts (SACs) exhibit peroxidase-like, oxidase-like, catalase-like, and glutathione peroxidase-like activity. Fe–N/C SACs are successfully applied to control the intracellular H₂O₂ level. This study not only explores the types of SACs mimicking enzymes but also provides opportunities for SACs in biomedical and other bioengineering applications.
