Research Progress in the Application of Single-atom Catalysts in Biomedical Field

Single-atom catalysts (SACs) have the highest atom economy, precisely located active sites, unique metal coordination environments. These merits of SACs greatly increase the specific activity of metal atom, thus providing great potential for achieving better catalytic activity and selectivity. The metal catalytic active sites of SACs and natural enzymes are similar in structure, physical and chemical properties, and have better catalytic activity and selectivity. Theoretically, SACs can replace natural enzymes in the field of biomedicine. Based on the latest research work, the preparation technology of SACs and its application in the biomedical field are reviewed in this paper, and the challenges and future development direction of SACS in the biomedical field were briefly prospected.
