Though nanozymes are successfully applied in various areas, the increasing demands facilitate the exploitation of nanozymes possessing higher activity and more functions. Natural enzyme‐linked receptors (ELRs) are critical components for signal transductions in vivo by expressing activity variations after binding with ligands. Inspired by this, the defect‐engineered carbon nitrides (DCN) are reported...
Multiple enzymes‐induced biological cascade catalysis guides efficient and selective substrate transformations in vivo. The biomimetic cascade systems, as ingenious strategies for signal transduction and amplification, have a wide range of applications in biosensing. However, the fragile nature of enzymes greatly limits their wide applications. In this regard, metal–organic frameworks (MOFs) with...
Nanomaterials with enzyme‐like activities, coined nanozymes, have been researched widely as they offer unparalleled advantages in terms of low cost, superior activity, and high stability. The complex structure and composition of nanozymes has led to extensive investigation of their catalytic sites at an atomic scale, and to an in‐depth understanding of the biocatalysis occurring. Single‐atom catalysts...
Single‐atom catalysts (SACs) have attracted extensive attention in the catalysis field because of their remarkable catalytic activity, gratifying stability, excellent selectivity, and 100% atom utilization. With atomically dispersed metal active sites, Fe‐N‐C SACs can mimic oxidase by activating O2 into reactive oxygen species, O2−• radicals. Taking advantages of this property, single‐atom nanozymes...
