Abstract:

Nanozymes featuring with economic cost, high stability, tunable properties, have captured broad interest to break through the limitations of enzymes in practice. The emergency of single-atom materials pushes forward the nanozymes research into the atomic level. Single-atom materials with high atomic utilization efficiency, unique coordination environments and strong metal-support interactions offer great opportunities to reveal their structure-activity relationship and regulate their enzyme-like activities. In this review, recent advances of single-atom materials for enzyme mimicking and biomedical applications were depicted. First, the regulation strategies and catalytic mechanisms of enzyme-like activities were discussed in detail. Then, the applications of single-atom nanomaterials for enzyme mimicking were elucidated in terms of cancer treatment, antioxidant therapy, antibacterial and biosensing. Finally, the limitations, challenges and development prospects of single-atom nanomaterials for enzyme-like catalysis were proposed.

Key words: Single-atom material, Enzyme-like catalysis, Nanozymes, Biomedical application
