“…Additionally, other factors, namely specific coordination, channel size, and degree of chirality are also considered persuasive for biosensing applications [122]. Water-stable two-dimensional MOF based Cu(bpy) 2 (OTf) 2 nanosheets were used for the fluorescent detection of glucose and H 2 O 2 with their inherent peroxidase-like catalytic activity (Figure 8) [123].

Metal-organic frameworks (MOFs) are a fascinating class of porous crystalline materials constructed by organic ligands and inorganic connectors. Owing to their noteworthy catalytic chemistry, and matching or compatible coordination with numerous materials, MOFs offer potential applications in diverse fields such as catalysis, proton conduction, gas storage, drug delivery, sensing, separation and other related biotechnological and biomedical applications. Moreover, their designable structural topologies, high surface area, ultrahigh porosity, and tunable functionalities all make them excellent materials of interests for nanoscale applications. Herein, an effort has been to summarize the current advancement of MOF-based materials (i.e., pristine MOFs, MOF derivatives, or MOF composites) for electrocatalysis, photocatalysis, and biocatalysis. In the first part, we discussed the electrocatalytic behavior of various MOFs, such as oxidation and reduction candidates for different types of chemical reactions. The second section emphasizes on the photocatalytic performance of various MOFs as potential candidates for light-driven reactions, including photocatalytic degradation of various contaminants, CO2 reduction, and water splitting. Applications of MOFs-based porous materials in the biomedical sector, such as drug delivery, sensing and biosensing, antibacterial agents, and biomimetic systems for various biological species is discussed in the third part. Finally, the concluding points, challenges, and future prospects regarding MOFs or MOF-based materials for catalytic applications are also highlighted.

“…Moreover, similar to colorimetric biosensing, the typical GOx-HRP biomimetic cascade system was also used to catalyze the fluorescent substance to produce fluorescent signals for the assay of glucose. [86] It is worth mentioning that Willner et al introduced a CL substrate (luminol) into the enzymes-nanozymes (GOx and POD mimic) cascade system, where luminol can produce CL signals in the presence of Cu 2+ -modified MOF NPs with PODlike activity and H 2 O 2 (Figure 5e). [97] Based on this, a CL biosensor was established and successfully applied to determine glucose with a linear range covering 1-50 × 10 −6 m (Figure 5f).…”

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 porous structures, unique nano/microenvironments, and good biocompatibility have been skillfully used as carriers to immobilize enzymes for shielding them against hash surroundings and improving the catalytic efficiency. For another, nanomaterials with enzyme‐like properties and brilliant stabilities (nanozymes), have been widely applied to ameliorate the low stability of the enzymes. Inheriting the abovementioned merits of MOFs, the performances of MOFs‐immboilized nanozymes could be significantly enhanced. Furthermore, in addition to carriers, some MOFs can also serve as nanozymes, expanding their applications in cascade systems. Herein, recent advances in the fabrication of efficient MOFs‐involving enzymes/nanozymes cascade systems and biosensing applications are highlighted. Integrating diversified signal output modes, including colorimetry, electrochemistry, fluorescence, chemiluminescence, and surface‐enhanced Raman scattering, sensitive detection of various targets (including biological molecules, environmental pollutants, enzyme activities, and so on) are realized. Finally, challenges and opportunities about further constructions and applications of MOFs‐involving cascade reaction systems are briefly put forward.

“…2D Cu(bpy) 2 (OTf) 2 (bpy, 4,4‐bipyridine; OTf, trifluromethanesulfonate) MOF nanosheets were reported to have intrinsic peroxidase‐like activity, which was utilized to achieve fluorescent detection for H 2 O 2 and glucose. [ 42 ] Thorium‐MOF was found to be an artificial peroxidase, and its affinity with substrate was even higher than the nature enzyme (HRP). By incorporating with urease, a sensitive colorimetric biosensor was developed for the detection of uric acid in biological samples.…”
