In this review, we gather a great deal of information about magnetic nanocomposites, which are made from the combination of Fe 3 O 4 magnetic nanoparticles (MNPs) and metal-organic frameworks (MOFs). Due to the high saturation magnetization, biocompatibility, low toxicity, stability, and costeffectiveness, MNPs have attracted a lot of interest in recent years. Furthermore, MOFs, which are porous materials, formed by the connection between organic linkers and metal ions. The combination of MNPs and MOFs results in the formation of magnetic framework composites (MFCs). The information about the MFCs is classified according to their applications and we

“…The application of MOFs as sensors depends on the versatile properties including electrochemical performance and luminescence emission originated from the interaction between analytes and organic ligands or metal ions contained in the frameworks . In general, MOF materials with fixed pore structure and chemical functionality can bond with suitable guest molecules through special surface chemistry such as hydrogen bond, covalent bond and the interaction between electron donor and acceptor . With these prerequisites, it is certain that MOFs could both recognize molecules and generate diverse signals (strong fluorescence, change of color and electrochemical signal), which can be easily monitored by sensing devices.…”

“…They also revealed that the MIL‐53(Fe)‐based mimic peroxidase could be a clinical application for UA detection in human urine and serum. To improve the peroxidase‐like activity, Wu et al developed a MIL‐100(Fe) shell coated Fe 3 O 4 magnetic catalyst for detecting cholesterol at a trace level . The Fe 3 O 4 provided extra Fe catalytic sites to decompose H 2 O 2 into ·OH.…”

Among uncountable MOF materials, iron-containing metal organic frameworks (Fe-MOFs) have excellent potential in practical applications owing to their many fascinating properties, such as diverse structure types, low toxicity, preferable stability, and tailored functionality. Here, recent research progresses of Fe-MOFs in attractive features, synthesis, and multifunctional applications are described. Fe-MOFs with porosity and tailored functionality are discussed according to the design of building blocks. Four types of synthetic methods including solvothermal, hydrothermal, microwave, and dry gel conversion synthesis are illustrated. Finally, the applications of Fe-MOFs in Li-ion batteries, sensors, gas storage, separation in gas and liquid phases, and catalysis are elucidated, focusing on the mechanism. The aim is to provide prospects for extending Fe-MOFs in more practical applications.Iron-Based Metal Organic Frameworks www.advancedsciencenews.com

“…In this regard, colorimetric methods for cholesterol detection have gained considerable attention due to its visual detecting capability. Most of them have relied on natural peroxidase or peroxidase-like nanozyme, which combines with ChOx, and chromogenic substrate including 3,3′,5,5′-tetramethylbenzidine (TMB) or 2,2′-azino-bis(3-ethylbenzo-thiazoline-6-sulfonic acid) diammonium salt (ABTS) (Hayat et al, 2015 ; Kim et al, 2015 ; Wu et al, 2017 ; Chung et al, 2018 ). In the presence of cholesterol, ChOx oxidized cholesterol to produce H 2 O 2 , which subsequently activated peroxidase or peroxidase-mimicking material to oxidize TMB or ABTS into blue or green colored product, respectively.…”

Paper-based test strip consisting of cerium oxide nanoparticles (nanoceria) as hydrogen peroxide (H 2 O 2 )-dependent color-changing nanozymes and cholesterol oxidase (ChOx) has been developed for convenient colorimetric determination of cholesterol without the need for chromogenic substrate. The construction of the cholesterol strip begins with physical adsorption of nanoceria on the paper surface, followed by covalent immobilization of ChOx via silanization, chitosan-mediated activation, and glutaraldehyde treatment of the nanoceria-embedded paper matrices. In the presence of cholesterol, ChOx catalyzes its oxidation to produce H 2 O 2 , which forms peroxide complex on the nanoceria surface and induces visual color change of the nanoceria-embedded paper from white/light yellow into intense yellow/orange, which was conveniently quantified with an image acquired by a conventional smartphone with the ImageJ software. Using this strategy, target cholesterol was specifically determined down to 40 μM with a dynamic linear concentration range of 0.1–1.5 mM under neutral pH condition, which is suitable to measure the serum cholesterol, with excellent stability during 20 days and reusability by recovering its original color-changing activity for 4 consecutive cycles. Furthermore, the practical utility of this strategy was successfully demonstrated by reliably determining cholesterol in human blood serum samples. This study demonstrates the potential of self color-changing nanozymes for developing colorimetric paper strip sensor, which is particularly useful in instrumentation-free point-of-care environments.
