Preparation of magnetic composite titanium-based MOFs for rapid and effective lead ion adsorption in aqueous solution

Lead contamination constitutes a significant risk to ecology and human beings, which necessitates the development of efficient lead removal adsorbents. In this context, magnetic composite MOFs are promising as they combine the tunable properties and high specific surface area of MOFs with the easy recyclability of magnetic materials. In this study, a novel magnetic composite material, DMP-MIL@Fe3O4, was synthesized by loading magnetic Fe3O4 on titanium-based MOFs and postmodifying it with 4,6-diamino-2-mercaptopyrimidine. The adsorption capacity was maximized within 20 min at pH 6.0 and room temperature. At the same time, it has very high adsorption efficiency for lead ions, with a maximum adsorption capacity of 200.1 mg/g. The adsorption mechanism of DMP-MIL@Fe3O4 was elucidated by kinetic, isothermal and thermodynamic analyses. Pseudo-second-order modeling showed that the binding of functional groups to lead ions was the key rate-limiting step. Isotherm modeling confirmed that multiple functional groups work together to promote the adsorption of lead ions, while thermodynamic analysis demonstrated the spontaneous endotherm of the adsorption process. DMP-MIL@Fe3O4 also exceled in selective adsorption of lead ions and recyclability.

Targeting long non-coding RNA H19 in Subchondral Bone Osteocytes Alleviates Cartilage Degradation in Osteoarthritis.

Emerging evidence suggests long non-coding RNA (lncRNA) H19 is associated with osteoarthritis (OA) pathology. However, how H19 contributes to OA has not been reported. This study aims to investigate the biological function of H19 in OA subchondral bone remodeling and OA progression. Clinical joint samples and OA animal models induced by medial meniscus destabilization (DMM) surgery were used to verify the causal relationship between osteocyte H19 and OA subchondral bone and cartilage changes. MLO-Y4 osteocyte cells subjected to fluid shear stress were used to verify the mechanism underlying H19-mediated mechano-response. Finally, the antisense oligonucleotide (ASO) against H19 was delivered to mice knee joints by magnetic metal-organic framework (MMOF) nanoparticles in order to develop a site-specific delivery method for targeting osteocyte H19 for OA treatment. Both clinical OA subchondral bone and wildtype mice with DMM-induced OA exhibit aberrant higher subchondral bone mass with more H19 expressing osteocytes. On the contrary, osteocyte-specific deletion of H19 mice is less vulnerable to DMM-induced OA phenotype. In MLO-Y4 cells, H19-mediated osteocyte mechano-response through PI3K/AKT/GSK3 signals activation by EZH2-induced H3K27me3 regulation on PP2A inhibition. Targeted inhibition of H19 (using ASO-loaded MMOF) substantially alleviates subchondral bone remodeling and OA phenotype. In summary, our results provide new evidence that the elevated H19 expression in osteocytes may contribute to aberrant subchondral bone remodeling and OA progression. H19 appears to be required for the osteocyte response to mechanical stimulation, and targeting H19 represents a new promising approach for OA treatment.

Efficient Nanofibrous Electromagnetic Wave Absorber Inspired by Spider Silk Hunting.

With the rapid advancements in wireless communication and radar detection technologies, there has been a significant uptick in the utilization frequency of electromagnetic waves across both civilian and military sectors, consequently generating substantial electromagnetic radiation and interference. These electromagnetic pollutants present a considerable threat to public health and information security. Consequently, materials capable of absorbing and mitigating electromagnetic pollution have garnered significant attention.The nanomaterials with multiple components and various heterogeneous interfaces have been considered as preferred efficient electromagnetic wave (EMW) absorbers. In this work, carbon nanofibers doped with magnetic metal oxide particles (Co/Ni-CNFs) are prepared by electrospinning and heat treatment. In these samples, the minimum reflection loss can reach -40.13dB at 4.6mm, and the widest effective absorption bandwidth is 4.4GHz. The excellent microwave absorption is attributed to the appropriate impedance matching. The electromagnetic parameters of Co/Ni-CNFs are balanced by adjusting the concentration of magnetic metal-organic framework material (MOFs) in the precursor solution. It is believed that this work can provide a reference for developing lightweight, flexible, and robust electromagnetic wave-absorbing materials.

Rapid screening of xanthine oxidase inhibitors from Ligusticum wallichii by using xanthine oxidase functionalized magnetic metal-organic framework.

In this study, xanthine oxidase was immobilized for the first time using a novel magnetic metal-organic framework material (Fe3O4-SiO2-NH2@MnO2@ZIF-8-NH2). A ligand fishing method was established to rapidly screen XOD inhibitors from Ligusticum wallichii based on the immobilized XOD. Characterization and properties of the immobilized enzyme revealed its excellent stability and reusability. A ligand was screened from Ligusticum wallichii and identified as ligustilide by ultra-high performance liquid chromatography tandem mass spectrometry. The IC50 value of ligustilide was determined to be 27.70 ± 0.13μM through in vitro inhibition testing. Furthermore, molecular docking verified that ligustilide could bind to amino acid residues at the active site of XOD. This study provides a rapid and effective method for thepreliminary screening of XOD inhibitors from complex natural products and has great potential for further discovery of anti-hyperuricemic compounds.

Magnetic nanoparticle-decorated metal organic frameworks for chemiluminescence detection of glutathione.

A chemiluminescence (CL) method for determination of glutathione (GSH) was developed with magnetic nanoparticle-decorated metal organic frameworks (Fe3O4 NPs@Cu-TATB). The composite material was synthesized via a hydrothermal method and glutathione (GSH) can be detected by both visual and chemiluminescence (CL) methods. The synthesized Fe3O4 NPs@Cu-TATB exhibited excellent catalytic activity in the luminol-H2O2 CL system. The mechanism revealed that three types of oxygen-containing radicals (ROS) were generated in this system. As GSH can reduce the catalytic effect of generated ROS radicals, the inhibiting CL signal was produced in the Fe3O4 NPs@Cu-TATB-luminol-H2O2 system. Based on the established CL system, the detection limits for GSH using CL and visual methods were found to be 0.3 µM and 0.7 µM, respectively. This low-cost and convenient detection method can be applied to the determination of GSH content in human blood.

Low-dimensional metal-organic frameworks: a pathway to design, explore and tune magnetic structures.

The magnetic structure adopted by a material relies on symmetry, the hierarchy of exchange interactions between magnetic ions and local anisotropy. A direct pathway to control the magnetic interactions is to enforce dimensionality within the material, from zero-dimensional isolated magnetic ions, one-dimensional (1D) spin-chains, two-dimensional (2D) layers to three-dimensional (3D) order. Being able to design a material with a specific dimensionality for the phenomena of interest is non-trivial. While many advances have been made in the area of inorganic magnetic materials, organic compounds offer distinct and potentially more fertile ground for material design. In particular magnetic metal-organic frameworks (mMOFs) combine magnetism with non-magnetic property functionality on the organic linkers within the structural framework, which can further be tuned with mild perturbations of pressure and field to induce phase transitions. Here, it is examined how neutron scattering measurements on mMOFs can be used to directly determine the magnetic structure when the magnetic ions are in a 2D layered environment within the wider 3D crystalline framework. The hydrated formate, in deuterated form, Co(DCOO)2·2D2O, which was one of the first magnetic MOFs to be investigated with neutron diffraction, is reinvestigated as an exemplar case.

Magnetic Fe3O4@MOF@aptamer-mediated entropy-driven fluorescence biosensor for multiplexed and DNA extraction- and amplification-free detection of pathogenic bacteria

Rapid and early identification of pathogenic bacteria in food and clinical samples is critical for infectious disease control and precision medicine. In this study, we present a novel Magnetic Fe3O4@metal–organic framework (MOF)@Aptamer-based Entropy-driven fluorescence biosensor combined with mesophilic Clostridium butyricumArgonaute (CbAgo) for multiplexed and DNA extraction- and amplification-free detection of pathogenic bacteria, termed the MAEA biosensor. In this study, magnetic zirconium-based MOF nanoparticles were modified with a phosphorylated aptamer as an efficient signal converter, which recognized the pathogens and released the complementary DNA to activate the entropy-driven circuit reaction. The highly efficient catalytic DNA circuit and isothermal enzyme-free format produce large amounts of guide DNA. CbAgo exerts precise and highly efficient endonuclease activity under the guidance of guide DNA, which makes the MAEA biosensor useful for multiplexed and DNA extraction- and amplification-free detection of pathogenic bacteria with high sensitivity (<102 CFU/mL). This study demonstrates a highly selective and reliable magnetic Fe3O4@MOF@aptamer-based biosensor using CbAgo for simultaneously detecting multiple pathogenic bacteria, providing a potential tool for other infectious disease pathogens with convenient operation and high sensitivity.

Facile manufacturing of carbon nanotube/ZIF-67-derived cobalt composite aerogel with high-efficiency electromagnetic wave absorption

Developing high-efficiency electromagnetic wave (EMW) absorbers by designing dielectric/magnetic components and microstructure in a straightforward, scalable method is highly desirable yet challenging. Here, we introduce a novel hierarchical composite aerogel-based EMW absorber composed of conductive carbon nanotubes (CNTs) and magnetic metal-organic framework (MOF) derivatives, integrated with sustainable cellulose nanofibers (CNF) derived carbon. This composite was prepared using a scalable freeze-casting followed by carbonization approach. Freeze casting enabled the creation of porous monoliths with high specific surface areas and customizable pore sizes and porosities, crucial for enhancing EMW reflection and scattering. Carbonization enhanced composite conductivity and stabilized the cobalt (Co)/carbon nanoparticles derived from ZIF-67 within the carbon matrix. CNF-derived carbon facilitated the efficient integration of ZIF-derived Co nanoparticles and CNTs, resulting in a robust 3D aerogel structure. The synergistic effects of CNT conductive paths and Co nanoparticles' magnetic losses provided an efficient route to enhance EMW absorption. Moreover, the creation of numerous heterogeneous interfaces augmented polarization losses, significantly enhancing EMW loss capability. Remarkably, the composite achieved outstanding EMW absorption, with a minimum reflection loss of -71.03 dB at a filling ratio of merely 10 wt.% and an effective absorption bandwidth of 4.64 GHz, comparable to leading EMW absorbers reported to date.

Fabrication of metal‐organic frameworks macro-structures for adsorption applications in water treatment: A review

Metal-organic frameworks (MOFs) are emerging porous organic–inorganic hybrid materials composed of metal centers/clusters and various organic ligands, which are widely used in water and wastewater treatment applications due to their large specific surface area, high porosity, tunable chemical properties and abundant active sites. However, pure MOFs powders have limitations such as poor recovery, blocked pipelines and secondary contamination in practical water treatment processes. Enabling the magnetization of MOFs or immobilizing MOFs as macroscopic MOFs materials offers new opportunities to improve solid–liquid separation performances of powdered MOFs. Besides, macroscopic MOFs materials with outstanding adsorption performance and mechanical properties by the combining of 3D particles and 2D nanosheets MOFs with other substrates are widely used for water treatment. This paper provides a comprehensive review of recent advancements in MOFs macro-structures. We firstly summarized the synthesis strategies of magnetic MOFs composites and various MOFs macro-structures such as hydrogels/aerogels, membranes, beads/spheres, others composites, etc. which can be constructed by various methods, including in-situ growth, solvothermal method, direct mixing, self-assembly, layer-by-layer growth, etc. Innovative preparation strategies to improve the mechanical properties of MOFs macro-structures were highlighted. Next the article discusses its application for adsorptive removal of various pollutants (i.e., dyes, heavy metal ions, oils and organic pollutants) from water. Finally, the challenges of macroscopic MOFs materials and their practical applications are presented, while future research directions to overcome these existing limitations are also pointed out.

In this study, a magnetic porous polymer composite with both hydrophilic and hydrophobic groups was synthesized for magnetic solid phase extraction (MSPE) of milk substrates. Optimization was conducted on various parameters, including adsorption dose, solution pH, adsorption time, and some elution conditions. Coupled with a high-performance liquid chromatography fluorescence detector, a novel MSPE method for determination of norfloxacin (NFX), ciprofloxacin (CIP), and enrofloxacin (ENR) in milk was developed based on magnetic metal organic framework polystyrene polymer (Fe3O4@MOF@PLS) as adsorbent. The Fe3O4@MOF@PLS exhibited significantly improved adsorption performance compared to MOF and PLS. Under optimized experimental conditions, the method exhibited good linearity for the three fluoroquinolones (FQs) in the range of 0.5-1000 μg/kg, with limit of detections (LODs) ranging from 0.21 to 1.33 μg/kg, and limit of quantitations (LOQs) from 0.71 to 4.42 μg/kg. The relative standard deviation (RSD) for the three FQs were 3.4-8.8%. The recoveries of three FQs in milk samples ranged from 84.2% to 106.2%. This method was successfully applied to the detection of three FQs in 20 types of milk, demonstrating its simplicity, speed, and effectiveness in analyte enrichment and separation. The method presented advantages in adsorbent dosage, adsorption time, LODs, and LOQs, making it valuable for the analysis and detection of FQs in milk.

Novel cofactor regeneration-based magnetic metal–organic framework for cascade enzymatic conversion of biomass-derived bioethanol to acetoin

Upgrading biomass-derived bioethanol to higher-order alcohols using conventional biotechnological approaches is challenging. Herein, a novel, magnetic metal–organic-framework-based cofactor regeneration system was developed using ethanol dehydrogenase (EtDH:D46G), NADH oxidase (NOX), formolase (FLS:L482S), and nicotinamide adenine dinucleotide (NAD+) for converting rice straw-derived bioethanol to acetoin. A magnetic zeolitic imidazolate framework-8@Fe3O4/NAD+ (ZIF-8@Fe3O4/NAD+) regeneration system for cell-free cascade reactions was introduced and used to encapsulate EtDH:D46G, NOX, and FLS:L482S (ENF). ZIF-8@Fe3O4/NAD+ENF created an efficient microenvironment for three-step enzyme cascades. Under the optimized conditions, the yield of acetoin from 100 mM bioethanol using ZIF-8@Fe3O4/NAD+ENF was 90.4 %. The regeneration system showed 97.1 % thermostability at 50 °C. The free enzymes retained only 16.3 % residual conversion, compared with 91.2 % for ZIF-8@Fe3O4/NAD+ENF after ten cycles. The magnetic metal–organic-framework-based cofactor regeneration system is suitable for enzymatic cascade biotransformations and can be extended to other cascade systems for potential biotechnological applications.

Magnetic-driven metal–organic framework nanorobots for the coupling engineering of electronic waste treatment and environmental remediation

Gold recycling from secondary sources provides an economically viable and sustainable approach to meet the increasing global demand for this precious metal. However, gold resources are inherently scarce. To address this issue, the present study presents an innovative solution: dimercaptosuccinic acid functionalized magnetic metal–organic framework nanorobots (MNR-MOF-DMSA). These nanorobots are designed for swift, efficient, and selective capture of Au(III) trace amounts from complex aqueous mixtures. MNR-MOF-DMSA showed an ultra-high adsorption capacity, better selectivity, and reusability with long-term stability, as it can selectively extract over 94 % of Au(III) from complex e-waste leachate, and the adsorption capacity can reach 1716 mg/g (at pH 5 in 3 h) in harsh acidic condition followed Langmuir model. In addition, after conducting a detailed mechanistic analysis, it was discovered that the selective adsorption behaviors observed were due to the combined effect of several factors, including the reduction of sulfhydryl groups, the coordination interactions between amide groups and Au(III) ions, as well as the electrostatic interactions between protonated amino and AuCl4- ions. It is also worth mentioning that the better catalytic properties of the developed hybrid MOF (MNR-MOF-DMSA-Au) were due to the reduction of Au(III) to Au(0). This study proposes new ways to recover and reuse gold e-waste for a sustainable future, as well as environmental protection and remediation.

This study utilized computational simulation and surface molecular imprinting technology to develop a magnetic metal-organic framework molecularly imprinted polymer (Fe3O4@ZIF-8@SMIP) capable of selectively recognizing and detecting multiple fluoroquinolones (FQs). The Fe3O4@ZIF-8@SMIP material was synthesized using the “common” template-ofloxacin, identified by computational simulation, demonstrating notable adsorption capacity (88.61–212.93 mg g−1) and rapid mass-transfer features (equilibration time: 2–3 min) for all tested FQs, consistent with Langmuir adsorption model. Subsequently, this material was employed as a magnetic solid-phase-extraction adsorbent for adsorption and detection of multiple FQs by combining with high performance liquid chromatography. The developed method exhibited good linearity for various FQs within the concentration range of 0.1–500 μg L−1, with low limit of detection (0.0605–0.1529 μg L−1) and limit of quantitation (0.2017–0.5097 μg L−1). Satisfactory recoveries (88.38–103.44%) were obtained when applied to spiked food samples, demonstrating the substantial potential of this Fe3O4@ZIF-8@SMIP material for rapid enrichment and identification for multiple FQs residues.

Within the domain of materials science and engineering, significant progress has led to the emergence of innovative materials based on magnetic MOFs, positioning them as promising candidates in the field of catalysis. This research aims to elaborate on the development of a finely tailored magnetic MOF composite; Ni-BDC (Nickel benzene-1,4-dicarboxylate) microflakes which was synthesized through a straightforward in-situ solvothermal approach. Extensive investigations into the structural properties of the resultant hybrid composite were carried out using various characterization techniques encompassing X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FT-IR), field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), Brunauer-Emmett-Teller (BET) analysis, atomic absorption spectroscopy (AAS), energy-dispersive X-ray spectroscopy (EDX), thermogravimetric analysis (TGA) and vibrating sample magnetometry (VSM). The developed material demonstrated remarkable efficiency in expediting the synthesis of a diverse array of pharmaceutically active 5-substituted 1H-tetrazole derivatives through a multicomponent coupling reaction involving substituted aldehydes, malononitrile, and sodium azide as key components. A noteworthy feature of this approach is its adherence to environmentally friendly reaction conditions, thus making it superior in comparison to previously established methodologies. Furthermore, a plausible mechanistic pathway has been proposed to elucidate the impressive performance of the developed catalytic system in the targeted reaction. It is anticipated that the current research will not only contribute to the purposeful designing of advanced magnetic MOF-based architectures but will also play a pivotal role in promoting sustainable practices in industrial processes, addressing pressing environmental and economic concerns.

Separable Metal-Organic Framework-Based Materials for the Adsorption of Emerging Contaminants.

Thousands of chemicals have been released into the environment in recent decades. The presence of emerging contaminants (ECs) in water has emerged as a pressing concern. Adsorption is a viable solution for the removal of ECs. Metal-organic frameworks (MOFs) have shown great potential as efficient adsorbents, but their dispersed powder form limits their practical applications. Recently, researchers have developed various separable MOF-based adsorbents to improve their recyclability. The purpose of this review is to summarize the latest developments in the construction of separable MOF-based adsorbents and their applications in adsorbing ECs. The construction strategies for separable MOFs are classified into four categories: magnetic MOFs, MOF-fiber composites, MOF gels, and binder-assisted shaping. Typical emerging contaminants include pesticides, pharmaceuticals and personal care products, and endocrine-disrupting compounds. The adsorption performance of different materials is evaluated based on the results of static and dynamic adsorption experiments. Additionally, the regeneration methods of MOF-based adsorbents are discussed in detail to facilitate effective recycling and reuse. Finally, challenges and potential future research opportunities are proposed, including reducing performance losses during the shaping process, developing assessment systems based on dynamic purification and real polluted water, optimizing regeneration methods, designing multifunctional MOFs, and low-cost, large-scale synthesis of MOFs.

Colorimetric aptasensor based on Fe3O4@MOF@Pt nanozymes for ultrasensitive detection of histamine in fish

The accurate determination of histamine in fish is imperative for food safety, given the toxic nature of this biogenic amine. This study presents an innovative colorimetric aptasensor for the ultrasensitive detection of histamine in fish, utilizing nanozymes based on magnetic metal-organic frameworks coated with Pt nanoparticles (Fe3O4@MOF@Pt), which exhibit high peroxidase-like catalytic activity, magnetism, and superior optical properties. The surface of Fe3O4@MOF@Pt nanozymes were modified with DNA strands complementary to the histamine aptamer, creating effective colorimetric probes. In the presence of histamine, these colorimetric probes compete with histamine molecules for aptamer binding on the enzyme plate. Color development is triggered by adding a TMB and H2O2 substrate solution to the enzyme plate. This competitive binding-based aptasensor allows for rapid and accurate histamine quantification within a linear range of 10 pM to 10 μM, and a notable detection limit of 6.23 pM. Furthermore, the sensor demonstrated excellent specificity, distinguishing histamine from l-histidine and other biogenic amines. Tested on mackerel samples, the aptasensor showed spiked recoveries of 91.4%–109.6%, validating its practical applicability. This sensor offers an ultrasensitive, specific, and reusable tool for histamine detection, representing a significant advancement in ensuring the safety of fish products.

Fast screening of α-glucosidase inhibitors from Ginkgo biloba leaf by using α-glucosidase immobilized on magnetic metal-organic framework.

In this study, a ligand fishing method for the screening of α-glucosidase inhibitors from Ginkgo biloba leaf was established for the first time using α-glucosidase immobilized on the magnetic metal-organic framework. The immobilized α-glucosidase exhibited enhanced resistance to temperature and pH, as well as good thermal stability and reusability. Two ligands, namely quercitrin and quercetin, were screened from Ginkgo biloba leaf and identified by ultra-high performance liquid chromatography-tandem mass spectrometry. The half-maximal inhibitory concentration values for quercitrin and quercetin were determined to be 105.69±0.39 and 83.49±0.79µM, respectively. Molecular docking further confirmed the strong inhibitory effect of these two ligands. The proposed approach in this study demonstrates exceptional efficiency in the screening of α-glucosidase inhibitors from complex natural medicinal plants, thus exhibiting significant potential for the discovery of antidiabetic compounds.

Surface methodology for optimized adsorption of hazardous organic pollutant from aqueous solutions via novel magnetic metal organic framework: Kinetics, isotherm study, and DFT calculations

An efficient way to remove Janus Green B (JGB) dye from contaminated water sources is using of magnetic cerium (III) metal–organic framework (MCe-MOF). Analytical methods such as PXRD, TEM, FESEM, FT-IR, PZC, and XPS were used in the characterization of the MCe-MOF microspheres in order to assess the phase, crystallinity, shape, surface characteristics, and chemical composition of the MCe-MOF material. Impressive physical characteristics of the synthesized MCe-MOF material included a high surface area of 1340.05 m2/g. Conversely, MCe-MOF’s magnetic saturation (MS) was measured at 36.47 emu.g−1. The purpose of the study was to determine if MCe-MOF could effectively remove JGB dye from wastewater by adsorption. Adsorption settings that were studied included pH, adsorbent dose, beginning dye concentration, contact time, and temperature. The JGB electrical characteristics, reactivity, and shape were ascertained through the application of density functional theory (DFT). The placement of electrophilic and nucleophilic attack sites is in good agreement with the molecular orbitals (HOMO and LUMO) and MEP results, according to DFT. Based on the findings, MCe-MOF had a high capacity for adsorbing JGB dye, with an adsorption data fit by pseudo-second-order kinetic models and the Langmuir isotherm. It was evident from the adsorption energy of 27.8 kJ.mol−1 that chemisorption was the mode of adsorption. The optimal conditions for attaining a high adsorption capacity were found to be pH 8 and 0.02 g of MCe-MOF dose. The adsorption process of JGB dye onto MCe-MOF was seen to be spontaneous, endothermic, and random, as indicated by the temperature-dependent increases in the thermodynamic parameters ΔGo, ΔHo, and ΔSo. The adsorption process was optimized through the application of Response Surface Methodology and Box-Behnken design (RSM, BBD). The successful removal of dyes from the MCe-MOF material was made possible by these methods. While π-π bonding happens through the interaction of aromatic rings, chemisorption entails the formation of chemical interactions between the adsorbate and adsorbent. Electrostatic interactions arise from the attraction or repulsion of charges between the adsorbate and adsorbent, and pore-filling happens when the adsorbate fills the adsorbent’s pores. For the removal of JGB dye from wastewater, MCe-MOF exhibits great potential as an adsorbent because of its numerous adsorption processes and high adsorption capacity.
