“…[ 9 ] Since the discovery of magnetic Fe 3 O 4 nanoparticles exhibiting intrinsic horseradish peroxidase (HRP)‐like catalytic activity, a significant number of nanomaterials (e.g., noble metal, metal oxides, metal organic frameworks (MOFs), covalent organic framework (COFs), and carbon materials) have been discovered that exhibit enzyme‐like catalytic activity. [ 10 ] Compared with natural enzymes, nanozymes exhibit several intrinsic advantages (e.g., low cost, high catalytic stability, easy preparation, good storage stability, and tunable catalytic activity) as a result they have achieved widespread usage in biosensing applications, [ 10e,11 ] environmental analysis, [ 12 ] food safety analysis, [ 13 ] and cancer therapy. [ 14 ] In addition, the emergence of state‐of‐the‐art nanozymes has provided an extremely promising opportunity for constructing novel biomimetic cascade catalytic nanoreactors.…”

Multiple enzyme-driven biological catalytic cascades occur in living organisms, guiding highly efficient and selective transformations of substrates. Inspired by the merits of these biological catalytic cascade systems, enormous efforts have been devoted to developing novel cascade catalytic systems to mimic biological cascade catalytic reactions over the past few years. Nanozymes, a class of enzyme mimics, are nanomaterials with enzyme-like catalytic activity. The emergence and development of nanozymes has significantly advanced the development of biomimetic cascade nanoreactors. Currently, biomimetic cascade nanoreactors driven by advanced nanozymes have been widely used and exhibit many advantages such as superior cascade catalytic efficiency and high stability, resulting in significant advancements in biosensing and biomedical applications. The latest advances in understanding the cascade catalytic mechanism of nanozyme-engineered biomimetic cascade catalytic nanoreactors and their progressive applications for biosensing and biomedical applications are comprehensively covered here. First, nanozyme and enzyme/nanozyme-engineered biomimetic cascade catalytic nanoreactors are categorized according to their catalytic mechanism and properties. Then, the biosensing and biomedical applications, including cancer therapy, antibacterial activity, antioxidation, and hyperuricemia therapy of the cascade catalytic systems are covered. The conclusion describes the most important challenges and opportunities remaining in this exciting area of research.

“…Over the last few decades, MOFs constructed by the coordination connection of organic ligands to the metal ions or clusters in a periodic manner have emerged as multifunctional porous materials for diverse applications on the basis of their tunable pore sizes, high specific surface areas and diverse chemical functionalities. [1][2][3][4][5][6] In recent years, tetravalent cerium [Ce IV ]based MOFs have attracted much growing research attentions due to their unique and attractive properties: (i) Lewis acidity similar to the widely studied Zr IV /Hf IV based MOFs; (ii) redox activity derived from the inherent switching tendency between the Ce 4 + /Ce 3 + redox couple; (iii) photocatalytic characteristics gifted by the ligand-to-metal charge transfer (LMCT) profiting from the low-lying empty 4f orbitals of Ce 4 + . [7,8] However, the syntheses and applications of Ce IV -MOFs are still in its infancy and challenging to be developed.…”

Cerium (IV)-based metal-organic frameworks (MOFs) are highly desirable due to their unique potential in fields such as redox catalysis and photocatalysis. However, due to the high reduction potential of Ce IV species in solution, it is still a great challenge to synthesize Ce IV -MOFs with novel structures, which are extremely dominated by the hexanuclear CeÀ O cluster inorganic building units (IBUs). Herein, a CeÀ O IBU chain containing Ce IV -MOF, CSUST-3 (CSUST: Changsha University of Science and Technology), was successfully prepared using the kinetic stabilization study of UiO-66(Ce)-NDC (H 2 NDC = 2,6naphthalenedicarboxylic acid). Furthermore, owing to the superior redox activity, Lewis acidity and semiconductor-like behavior owing to Ce 4 + , activated CSUST-3 was demonstrated to be an excellent catalyst for CO 2 chemical fixation. One-pot synthesis of styrene carbonate from styrene and CO 2 was achieved under mild conditions (1 atm CO 2 , 80 °C, and solvent free). Moreover, activated CSUST-3 was shown to be a remarkable co-catalyst-free photocatalyst for overall water splitting (OWS), rendering 59 μmol g À 1 h À 1 of H 2 and 22 μmol g À 1 h À 1 of O 2 under simulated sunlight irradiation (Na 2 S-Na 2 SO 3 as sacrificial agent).

“…Featuring topological diversity and ultrahigh porosity, nanoscale metal‐organic frameworks (MOFs), as crystalline porous materials built from metal ions/clusters and organic ligands, have elicited ripples of excitement in the field of nanozyme research as they can be precisely predesigned or post‐renovated to achieve well‐defined enzyme mimicry. [ 6 ] Practically, the enzyme‐like characteristics of MOFs represent not only the biocatalytic metal‐linker interactions, [ 7a,7b,7c,7d,7e,7f ] involving the electronic quantum confinement, valence electron activation, and unsaturated coordination sites, but also the uniformly distributed nanochannels, which spatially and accurately isolate catalytic sites and accelerate the in‐ and out‐diffusion of reactant species. Moreover, MOFs are unique from most nanozymes for their intrinsic bioactivities.…”

Metal‐organic frameworks (MOFs) are a versatile toolbox for the bioinspired design of nanozymes for antibacterial applications and beyond, however, designing a nanozyme by the hierarchical quasi‐MOF scheme remains largely unpracticed. This work exemplifies the preferential structure‐activity correlation of a bimetallic quasi‐MOF (Q‐MOFCe0.5) among three series of MOF‐derived peroxidase (POD) mimics. The biomimetic quasi‐MOFCe0.5 nanosheets accommodate both oxygen vacancy‐coupled multivalent redox cycles and photosensitive energy band layout, benefiting from the hierarchical heterojunction‐like 0D/2D interface featuring isolated nodes‐derived CeOCu sites upon the 2D decarboxylated MOF scaffold. These integrated unique merits enable the POD‐like Q‐MOFCe0.5 to generate sustained reactive oxygen species to effectively eradicate the surface‐adhered bacteria under visible light, resulting in significant inactivation of Escherichia coli (99.74 %) and Staphylococcus aureus (99.35%) in vitro, and potent disinfection of skin wounds in vivo in safe and on‐demand manners. It is hoped that this work can intensify the interventions of MOF nanozymes against the microbial world.
