“…coupled the fluorescent molecular 5‐aminoisophthalic acid (H 2 aip) with InCl 3 to prepare a 2D luminescent MOFs (In‐aip) via a solvothermal process, and then combined with GOx and HRP to form the cascade system. [ 85 ] Interestingly, the product o ‐benzoquinone immediately bonded with the amino group of aip 2− ligand through nucleophilic addition, leading to a significant decrease in the fluorescence intensity of the In‐aip (Figure 5c). Based on this phenomenon, the In‐aip‐based fluorescence biosensor was elaborately applied to assay the glucose with high selectivity and sensitivity (Figure 5d).…”

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.

“…[114,115] The reduction of H 2 O 2 can also be coupled with the oxidation of glucose by glucose oxidase (GOx) to detect the simple sugar, as demonstrated by Li and co-workers using luminescent In(AIP) MONs. [116] However, the more typical approach has been to couple the peroxidase activity of MONs with an oxidationsensitive chromophore, including 3,3″,5,5″-tetramethylbenzidine (TMB), [117][118][119] o-phenylenediamine, [120] thiamine, [121] or luminol. [122] This sensor setup allows one to generate a colorimetric response upon detection of H 2 O 2 or a corresponding analyte through redox chemistry.…”

offers advantages over simple inorganic nanosheets in that a diverse range of physical and chemical properties can be programmed into their crystalline structure (Figure 1). This distinct combination of properties makes MONs ideal for a wide range of catalysis, sensing, electronics, and separation applications which will be the focus of this review.Much of the early literature in this field focused on the development of novel MON architectures and new routes towards their synthesis. A diverse range of different metal ions and organic linkers have been used to construct MONs. [4] However the field has rapidly converged on a handful of popular secondary building units (SBUs) which dominate much of the literature thanks to their reliable formation of high aspect ratio nanosheets. Popular classes of MONs that have been widely applied by different groups in applications include those based on the metal paddlewheel (PW) motif, [5][6][7] axially capped Zr and Hf clusters, [8][9][10][11] 2D zeolitic imidazolate frameworks (ZIFs), [12][13][14] and square planar Ni, Co, and Cu SBUs. [15][16][17][18] The modular structure of MONs, ease of functionalization and diverse range of materials they can be combined with means that MONs can be readily "programmed" to provide the desired topology and properties required for a given application.A wide variety of methods have been explored to synthesize MONs, either "top-down" by the exfoliation of layered metalorganic frameworks (MOFs) or "bottom-up" by assembly of molecular building blocks directly into nanosheets. The majority of top-down approaches utilize mechanical energy to overcome inter-layer interactions, such as liquid-assisted ultrasonication, [19] shear-mixing, [20] and grinding/ball-milling, [13] or the less common freeze-thaw [21] and "scotch-tape" methods. [22,23] Other methods involving photochemical, [24] electrochemical, [25] and chemical intercalation, [26] have also been developed but are less widely used. Bottom-up methodologies typically utilize surfactants or modulators to inhibit crystal growth in one dimension, [12,27,28] or layering/interfacial methods to promote anisotropic growth. [15,29,30] The use of sacrificial 2D templates has also recently emerged a promising route. [31,32] Each approach has advantages and disadvantages in terms of the thickness, lateral dimensions, size distribution, quantity and quality of the MONs produced, and the best approach therefore varies depending on the application.

“…[ 189 ] Furthermore, the introduction of nanoparticles into MOFs changed the sensing behavior for H 2 O 2 detection to the quenching effect. [ 190 ] Notably, MOFs bearing the same metal center but different linker functionalities showed different sensing behaviors. The corresponding Cu‐based MOF cluster detected H 2 O 2 with a “turn‐off” response in the fluorescence spectra, with an LOD of 0.01 × 10 −6 m .…”

The success of MOFs has driven their development as a new tool for sensing analytes including toxic chemicals. [19][20][21] The MOF sensors can be applied in both environmental and biological systems. [22] The MOF sensor field has been established with the development of sensors for different metal ions, anions, and molecules. [23,24] The potential application of MOF sensors to the detection of heavy metal ions, toxic anions, and other hazardous species is of great interest. [25,26] Specifically, luminescence technology has allowed the roles of various MOF sites in analyte capture to be easily studied. [27][28][29] The precise use of MOFs is potentially a good tool for analyte detection. Furthermore, MOFs have been established as potential materials for selective, fast, and portable tools for sensing toxic chemicals, with the advantage of light-emitting properties. [30,31] Interestingly, these sensing models can operate in water and are pH stable with high efficiency. [32] Furthermore, MOFs are wellknown materials for the degradation of toxic chemicals. [33,34] Several reports have been published on MOF sensors for toxicant chemicals, such as metal ions, anions, organic solvents, pesticides, nitroaromatic compounds (NACs), chemical warfare agents, [35] and others. [36][37][38] Some reviews have summarized applications of MOFs in sensing and detection probes for ions and volatile organic compounds, [39] and MOF sensors in pesticide detection and absorption with their classification. [40] Others have summarized and analyzed interactions between hazardous compound adsorbates and MOFs. [41,42] The stability and applications of MOFs have been summarized by the research groups of Ding and coworkers. [43] Pehlivan and et al. summarized the role of fluorescence resonance energy transfer in elucidating molecular interactions utilized in biosensing tools. [44,45] Besides luminescence sensing, the reviewers summarized the progress of MOFs relevance in the various area including environment and medical science. [46] Recently, Liu and coworkers summarized the progress of MOFs and discussed the remaining challenges in drug delivery, [47] Garcia and coworkers studied and compared the MOFs as photocatalysts with common inorganic photocatalysts, [48] and Manos and coworkers studied and summarized MOFs challenges and prospects for ion-exchange and sorption applications. [49] Despite these meaningful reviews, the factors responsible for signal changes, mechanisms, and limits of detection have Mechanistic studies of materials able to detect hazardous and toxic chemicals, such as common organic solvents, pesticides, and nitroaromatic compounds (NACs), are critically important owing to the threat they pose to humans and the environment. Recently, porous luminescent metal-organic frameworks (MOFs) with multifunctional sites, high surface areas, and structural tunability have emerged as sensory devices for the detection of hazardous and toxic chemicals. Herein, recent progress regarding the mechanistic behavior of MOF sensors in the det...
