The limitation of enzymes encourages us to seek for the alternatives. Nanomaterials with enzyme-like activities, defined as nanozymes, have been widely investigated, possessing unparalleled features in different fields owing to their advantages of low cost, superior activity and high stability. The complex structures and composition lead to the extensive investigation of the catalytic sites at atomic scale and in-depth understanding of the nature of the biocatalysis. Recently, single-atom catalysts (SACs) characterized by atomically dispersive activity sites provide great opportunities to mimic metalloprotease, demonstrating great potential for the understanding of the catalytic mechanism and bridging the gap between natural enzyme and nanozyme. In this review, we briefly demonstrate the unique properties and the recent advances in the synthesis, characterization, and applications of SACs. Then, we will mainly cover the impressive progress in single-atom nanozymes and their applications in sensing, organic pollutants degradation and therapy. Finally, the major challenges and opportunities for further research on the marriage of nanozyme and SACs are presented.
