“…Pores can have sizes ranging from the micrometer scales to mesoscales [32,47,48]. In coordination polymers, such as the MOF-200, about 90% of their volume consists of pore voids, causing these porous materials to present lower crystal density [23,49,50]. These properties are fundamental for gas storage and separation processes, for example, and naturally, are considered singularities that makes MOFs stand out from other more conventional porous substances.…”

Several studies have shown the development of electrochemical biosensors based on enzymes immobilized in metal–organic frameworks (MOFs). Although enzymes have unique properties, such as efficiency, selectivity, and environmental sustainability, when immobilized, these properties are improved, presenting significant potential for several biotechnological applications. Using MOFs as matrices for enzyme immobilization has been considered a promising strategy due to their many advantages compared to other supporting materials, such as larger surface areas, higher porosity rates, and better stability. Biosensors are analytical tools that use a bioactive element and a transducer for the detection/quantification of biochemical substances in the most varied applications and areas, in particular, food, agriculture, pharmaceutical, and medical. This review will present novel insights on the construction of biosensors with materials based on MOFs. Herein, we have been highlighted the use of MOF for biosensing for biomedical, food safety, and environmental monitoring areas. Additionally, different methods by which immobilizations are performed in MOFs and their main advantages and disadvantages are presented.

“…This result may be attributed to the rigidity of the ZIF-8 structure, which reduces enzyme leaching. 127 A similar size effect was observed for PDA@GO x /ZIF-8, which significantly enhanced the recyclability of the immobilized enzyme; after 10 cycles, the activity of PDA@GO x /ZIF-8 was maintained at nearly 100%. 130 Weak interactions between the carrier and the target enzyme can also enhance reusability.…”

Enzyme catalysis enables complex biotransformation to be imitated. This biomimetic approach allows for the application of enzymes in a variety of catalytic processes. Nevertheless, enzymes need to be shielded by a support material under challenging catalytic conditions due to their intricate and delicate structures. Specifically, metal−organic frameworks and covalent−organic frameworks (MOFs and COFs) are increasingly popular for use as enzyme-carrier platforms because of their excellent tunability in structural design as well as remarkable surface modification. These porous organic framework capsules that host enzymes not only protect the enzymes against harsh catalytic conditions but also facilitate the selective diffusion of guest molecules through the carrier. This review summarizes recent progress in MOF-enzyme and COF-enzyme composites and highlights the pore structures tuned for enzyme encapsulation. Furthermore, the critical issues associated with interactions between enzymes and pore apertures on MOF-and COF-enzyme composites are emphasized, and perspectives regarding the development of high-quality MOF and COF capsules are presented.

“…Metal organic frameworks (MOFs) are a class of porous, high surface area materials that have been investigated for a myriad of applications, especially for gas se paration [ 15 ], gas storage [ 16 ], drug delivery [ 17 ], heterogeneous catalysis, and enzyme immobilization [ [18] , [19] , [20] , [21] ]. S.Nadar et al have done a lot of research on enzyme encapsulation in MOF materials, the immobilized lipase they prepared showed up to 54 % of residual activity (7 cycles of reuse), whereas it retained 90 % of residual activity (25 days) [ 22 ]; the immobilized glucoamylase they prepared exhibited up to 57 % of residual activity after(6 consecutive cycles of reuse), whereas it retained 91 % of residual activity (25 days) [ 23 ].…”
