“…However, future research should focus on better suited polymers for chemical sensing. Such candidates could be metal organic framework (MOFs) [ 25 ], polymers of intrinsic microporosity (PIMS) [ 26 ], or electroactive polymers (EAPs) [ 27 ], which are advanced materials that exhibit interesting properties for strain-based sensing. Butterfly MOFs, for instance, have been shown to exhibit conformal switching upon exposure to electric fields [ 28 ].…”

We discuss distributed chemical sensing based on the swelling of coatings of optical fibers. Volume changes in the coating induce strain in the fiber’s glass core, provoking a local change in the refractive index which is detectable by distributed fiber optical sensing techniques. We describe methods to realize different coatings on a single fiber. Simultaneous detection of swelling processes all along the fiber opens the possibility to interrogate thousands of differently functionalized sections on a single fiber. Principal component analysis is used to enable sensors for environmental monitoring, food analysis, agriculture, water quality monitoring, or medical diagnostics.

Assessment of glucose concentration is important in the diagnosis and treatment of diabetes. Since the introduction of enzymatic glucose biosensors, scientific and technological advances in nanomaterials have led to the development of new generations of glucose sensors. This field has witnessed major developments over the last decade, as the novel nanomaterials are capable of efficiently catalyzing glucose directly (i.e., act as artificial enzymes, therefore defined nanozymes) or to entrap enzymes that are able to oxidize glucose. Among other nanomaterials, metal-organic frameworks (MOFs) have recently provided a tremendous basis to construct glucose sensing devices. MOFs are large porous crystalline compounds with versatile structural and tuneable chemical properties. In addition, they possess catalytic, peroxidase-like, and electrochemical redox activity. This review comprehensively summarizes the general characteristics of MOFs, their subtypes, and MOF composites, as well as MOF-derived materials employed to construct electrochemical, optical, transistor, and microfluidic devices for the detection of glucose. They include enzymatic, nonenzymatic, wearable, and flexible sensing devices and methods. The review also outlines the design and synthesis of MOFs and the working principles of the different transductionbased glucose sensors and highlights the current challenges and future perspectives.

Biocatalytic metal-organic framework (MOF) composites, synthesized by interfacing MOFs with biocatalytic components, possess the unprecedented synergetic properties that is hard to achieve by the conventional strategies, represents one of the next-generation composite materials for diverse biotechnological applications. Until now , research on the applications of biocatalytic MOFs is still in its preliminary stage, with a wide variety of studies being focusing on the bioprotection role of MOFs. However, their diversity of building units, molecular-scale tunability, modular synthetic routes, and more detailed understanding of the heterogeneous MOF-biointerface could even lead to completely new applications and potentials beyond our current imagination. The most recent rapid advanced progress in biocatalytic MOFs present ground-breaking applications in smart and tunable biocatalysis, precision nanomedicine, vaccine and gene delivery, biosensing and nano-biohybrids. Herein, the general and advanced synthesis strategies for improving the materials properties of biocatalytic MOFs, from tuning biocatalytic activity to framework stability to synergistic properties with other materials, are summarized. Then, the latest state-of-the-art applications of the biocatalytic MOF systems and recent advanced developments that are shaping this emerging field are surveyed. Finally, to define promising research directions, a critical evaluation and future prospects for the potential applications of biocatalytic MOFs are provided.
