Infectious bone defect is a condition where infection and bone defect occur simultaneously. The simultaneous achievement of effective antimicrobial management and enhanced bone regeneration continues to present a major hurdle in musculoskeletal therapeutics. To address these limitations, we have developed a novel osteoconductive material, this material (PDA@Mg-MOF-LEV) consists of Magnesium-based metal-organic frameworks (Mg-MOF) particles loaded with the antibiotic levofloxacin (LEV) and coated with polydopamine (PDA), which integrates photothermal therapy with antibiotic delivery to combat bacterial drug resistance and facilitate bone tissue regeneration. Under near-infrared (NIR) irradiation, PDA@Mg-MOF-LEV particles demonstrate superior antibacterial efficacy and enhanced osteogenic potential. Drug release studies indicate that NIR irradiation significantly increases LEV release by 337% and Mg ions release by 196% compared to standard conditions. Furthermore, in vitro antibacterial assays confirm that NIR irradiation markedly enhances the antibacterial activity of PDA@Mg-MOF-LEV particles, achieving inhibition rates of 97.5 ± 1.45% against Escherichia coli ( E. coli ) and 98.5 ± 2.27% against Staphylococcus aureus ( S. aureus ). The photothermal therapy mediated by NIR irradiation not only enhances antibacterial efficacy but also directly stimulates osteogenic differentiation and calcium deposition in mBMSCs, positioning PDA@Mg-MOF-LEV as a multi-modal therapeutic platform for infective osteogenesis.

The integration of bio-inspired nanostructured metal-organic frameworks (MOFs) with textiles opens new frontiers for smart wearable systems. This study develops a mechanically robust superhydrophobic AgTCNQ-MOF hybrid fabric via in situ self-assembly, mimicking cactus spines to achieve water contact and sliding angles of 159.2° and 1.8°, respectively. The optimized textile demonstrates multifaceted functionality: 1) Ultrahigh oil-water separation performance (efficiency: 98.4%; flux: 18.0 kL·m −2 ·h −1 ); 2) Anti-icing capacity extending freezing onset from 105 s to 685 s under −20 °C; 3) Full-spectrum UV resistance (UVA: 2.5%, UVB: 2.7%) with 99.8% antimicrobial efficacy; 4) Autonomous self-cleaning via contaminant-removing rolling droplets; and 5) Outstanding mechanical flexibility (6000 cycles) coupled with ultrahigh solar-thermal efficiency (91.5%) enabled by AgTCNQ-derived ultrasmall-bandgap (0.47 eV) engineering, a notable advancement over conventional systems. A covalent interfacial anchoring strategy ensures exceptional durability, maintaining superhydrophobicity after 30 abrasion cycles or 200 h UV exposure. The ultrasmall-bandgap of AgTCNQ uniquely optimizes photon-to-thermal conversion while maintaining multifunctionality, which is a key innovation differentiating this platform. This synergy between bandgap-engineered nanoporosity and textile flexibility enables real-time environmental responsiveness. Such integration bridges nanotechnology and textile engineering to address wearable-environmental challenges, advancing applications in medical wearables, industrial filtration, and adaptive robotics.

The development of multifunctional coatings that simultaneously address corrosion resistance and hydrodynamic drag reduction is essential for the next generation of amphibious platforms such as electric vertical take-off and landing aircraft (eVTOLs), which frequently operate in harsh marine environments. Lightweight aluminum alloys, though widely used in eVTOL components due to their high strength-to-weight ratio, are inherently prone to localized corrosion and surface drag when exposed to saltwater immersion and dynamic fluid flow. To overcome these dual limitations, we present a biomimetic bifunctional coating inspired by the hierarchical silicification of diatom frustules. The system integrates a pH-responsive cobalt-based metal–organic framework (Co-MOF) loaded with benzotriazole (BTA), encapsulated within a layered silica shell and further modified with a fluorine-free, low-surface-energy HDTMS layer. This composite enables both environmentally triggered corrosion inhibitor release and robust superhydrophobicity (contact angle: 163.3° ± 1.2°, sliding angle: 2.3°). The coating retains a high impedance modulus (>10 9 Ω·cm 2 ) after 30 days of immersion in 3.5 wt% NaCl, with BTA release efficiency reaching 85 % under acidic conditions. Drag-reduction performance remains stable over 40 cycles, achieving a maximum drag reduction of 31.5 %. Meanwhile, after undergoing 10 abrasion cycles, the coating still maintained a contact angle of 147°, demonstrating hydrophobic properties. This work demonstrates a synergistic material platform tailored for eVTOL marine operations, offering a pathway to extend service life, reduce energy consumption, and support the advancement of low-altitude, low-carbon transportation technologies.

Developing high-performance and cost-effective anode materials is essential for advancing sodium-ion battery (SIB) technology. In this study, a dual–metal–organic framework (dual-MOF) strategy was employed to synthesize the Fe 2 Ni MIL MOF@ZIF-8 precursor. After high-temperature carbonization, this precursor was transformed into a composite comprising FeNi alloy nanoparticles encapsulated within N-doped carbon nanotubes (FeNi@NC). Benefiting from its unique three-dimensional porous architecture, the N-doped carbon nanotubes shorten Na + diffusion pathways and accelerate electron transport, while the FeNi alloy nanoparticles supply abundant electrochemical active sites and enhance electrical conductivity. Moreover, the carbon matrix effectively alleviates volume expansion by providing structural confinement. Consequently, when used as an anode for SIBs, it delivers an outstanding long-term cycling life (290.39 mAh g −1 after 1000 cycles at 0.5 A g −1 ) and a high capacity (385.68 mAh g −1 after 200 cycles at 0.1 A g −1 ). The present strategy holds great promise for deriving porous carbon-based materials from MOFs for next-generation energy-storage applications.

In this paper, two Al-MOFs, named as MIL-53(Al) and NH 2 -MIL-53(Al), have been synthesized using aluminum ions as metal center and terephthalic acid, 2-aminoterepthalic acid as organic ligands in aqueous medium, respectively. Then, these two materials were utilized to construct the electrochemical sensor for the detection of neohesperidin dihydrochalcone (NHDC). The X-ray diffraction (XRD), scanning electron microscopy (SEM), fourier transformation infrared spectra (FT-IR), brunauer-emmett-teller (BET) and X-ray photoelectron spectra (XPS) were used to characterize the microstructure and morphology of two Al-MOFs materials. Compared with the MIL-53(Al) modified electrode, the NH 2 -MIL-53(Al) electrode proved a superior catalytic effect for the redox of NHDC. Thereafter, the electrochemical redox behavior and mechanism of NHDC at the NH 2 -MIL-53(Al) modified electrode were evaluated by cyclic voltammetry (CV), and the adsorption mechanism between the NH 2 -MIL-53(Al) materials and NHDC was revealed by density functional theory (DFT) calculations. Under the optimal detection conditions, a fast and sensitive strategy for detecting NHDC was constructed by differential pulse voltammetry (DPV). The linear range of NHDC based on this method was 0.08–30.0 μmol/L with R 2 = 0.9969. The low limit of detection (LOD) is 17.2 nmol/L for NHDC. Additionally, the NH 2 -MIL-53(Al) modified electrode demonstrated its applicability to the determination of NHDC in mud film samples with recoveries of 98.6–99.9 %. The consequences were in great accordance with high-performance liquid chromatography (HPLC), implying the feasibility of the proposed method for the detection of NHDC in actual samples.

Photogenerated holes have emerged as critical mediators for activating peroxymonosulfate (PMS) in the coupled photocatalytic PMS activation system, enabling novel dual-channel activation pathway. A tandem system based on Fe-MOF@BiVO 4 (Vis/PMS/Fe-MOF@BVO) with spatially separated active sites was constructed to form a dual-channel activation mechanism. The BiVO 4 (010) face provides the active sites for photogenerated electrons to drive the Fe 3+ /Fe 2+ cycle and activate PMS, while the BiVO 4 (110) face serves as the active sites for photogenerated holes to activate PMS. Consequently, the Vis/PMS/Fe-MOF@BVO system achieved complete degradation of 10 mg/L BPA within 6 min, with a degradation rate constant (K obs ) of 0.74 min −1 . It also demonstrated high removal efficiency for various organic pollutants with excellent immunity to interference and reusability. This work provides a new insight into the coordinative mechanism for coupled photocatalysis and PMS activation system.

The Cu-based catalyst used for electrochemical CO 2 reduction reaction (CO 2 RR) is a capable approach to reducing greenhouse carbon emissions and producing high value-added multi-carbon (C2 + ) products. Unfortunately, the selectivity of the (C2 + ) products is still quite low. Therefore, it is imperative to develop persuasive electrocatalysts to facilitate the conversion of carbon dioxide into valuable chemical products. Here, we design a CuO Nanosheets catalyst with the phase composition of silver (Ag) and Ag metal–organic framework (Ag-MOF) by using the hydrothermal approach. A maximum ethylene faradaic efficiency (FE) of Ag-MOF/CuO NS is achieved as 45.72 % at −1.1 V (vs RHE), while those CuO NS and Ag/CuO NS show 31 % and 14.24 % respectively. Interestingly, the restructured porous nature of Ag-MOF doped CuO NS electrocatalyst is equipped with a high surface area with strong adsorption capacity of CO 2 and increases the oxygen vacancies abundance with high active sites for selective electrocatalysis activity based on as produced Ag-MOF on CuO surface. This indicates that, in heterostructured catalysts, the coordination between CuO and free carboxyl groups considerably can enhance the dimerization of *CO intermediates and provide a strong coordination environment to the Cu valence state with MOF for the selective electrocatalytic CO 2 reduction. Thereby, the reaction pathway is shifted from two electrons to a multi-electron by constructing the oxygen vacancies for the production of multi-carbon products.

Composite biomaterial systems facilitate regenerative medicine through component synergy. Herein, novel core–shell nanocomposites (N-HMMs) are prepared, with hollow mesoporous silica (HMSNs) as the core and magnesium-gallic acid metal–organic frameworks (Mg-MOFs) as the shell. N-HMMs are loaded with the small-molecule osteoinductive drug naringin (Nar) to form N-HMMs@Nar, which is integrated into methacrylate gelatin/polyethylene glycol diacrylate hydrogels (GelMA/PEGDA, GP) to construct N-HMMs@Nar@GP. N-HMMs@Nar@GP enables sustained release of Nar, bioactive Mg2+, and antioxidant gallic acid for synergistic anti-inflammation, osteogenesis, and angiogenesis of bone regeneration. GP adapts N-HMMs@Nar to the traumatic characteristics of bone defects and facilitates in situ treatments. In vitro studies have confirmed the composite materials’ biocompatibility, osteoinductive differentiation, and angiogenesis capabilities. The ability of N-HMMs@Nar@GP to enhance osteogenesis and angiogenesis is demonstrated in an in vivo tibial defect model using micro-CT and histopathological analysis. Therefore, N-HMMs@Nar@GP holds significant potential for application in the repair of bone defects.

Although natural enzymes exhibit high selectivity and catalytic efficiency, their complex structures and inherent variability limit the long-term monitoring capabilities. Metal-organic frameworks (MOFs) biomimetic mineralization offers stability protection for enzymes, but it increases diffusion obstruction and reduces activity of encapsulated enzymes. To overcome these challenges, a biosensor based on MOF-74 biomimetic mineralization of three enzymes and combined with arginine-derived carbon dots (Argdot) was designed for monitoring key indicators (glucose, lactic acid, and xanthine) of muscle fatigue. The Boron‑nitrogen co-doped porous carbon nanospheres/reduced graphene oxide electrode (B,NMCNS/rGO) was used as the sensing substrate and the MOF-74/enzyme/Argdot was served as selective recognition layer. The detection sensitivities for glucose, lactic acid, and xanthine are 182.4 nA μM −1 cm −2 , 386.6 nA mM −1 cm −2 , and 207.6 nA μM −1 cm −2 . The sensors exhibit excellent linear ranges that fully encompass the physiological concentration intervals of all three biomarkers in sweat, and maintain over 94 % of its current response over 60 day-storage. Experiments conducted under several conditions demonstrate that the sensing system can dynamically monitor the variation of glucose, lactic acid, and xanthine in sweat. This study highlights the considerable promise of a noninvasive and continuous sensing system for point-of-care assessment and effective management in sports health.

The selective pyrolysis of cellulose to levoglucosenone (LGO) remains challenging, primarily due to the lack of catalysts with tailored active sites and appropriate modification of cellulose microstructures, both critically determining reaction pathways and product selectivity. To realize the high-selectivity conversion of cellulose to LGO, this study synthesized metal-organic frameworks (MOFs) with tunable channel structures using ZIF-67 as the precursor, which were subsequently subjected to partial phosphidation to prepare MOF-derived phosphorized porous carbon (CoP/N-C) catalysts for the catalytic pyrolysis of amorphous cellulose (AMC). The effects of catalyst characteristics on the product distribution and LGO yield during AMC pyrolysis were systematically investigated using pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS) and a lab-scale setup, while the catalytic pyrolysis mechanisms under the coupled effects of catalyst properties and reaction conditions were comprehensively elucidated. Results revealed that CoP/N-C significantly enhanced LGO yield from AMC pyrolysis. Particularly, the CoP (100) /N-C catalyst (synthesized with a Co:P ratio of 9:100) demonstrated optimal performance, achieving maximum LGO yields of 24.76 wt% in Py-GC/MS experiments and 18.89 wt% in lab-scale tests under optimized conditions (pyrolysis temperature: 320℃, catalyst:AMC ratio: 4:1). This study systematically revealed the structure-activity relationship between catalyst characteristics and LGO formation mechanisms, providing critical insights for further catalyst optimization and LGO yield enhancement.

Precise detection of hydrogen sulfide (H 2 S), a key spoilage marker in premium foods, is essential for maintaining both flavor and safety. However, conventional sensors often struggle to achieve high sensitivity, stability, and low power consumption simultaneously. Here, we report a mixed-potential type gas sensor based on Cu-MOF sensing electrode, K 2 Fe 4 O 7 solid electrolyte, and Au reference electrode for rapid and non-destructive food freshness evaluation. The sensor achieves an ultra-low detection limit (LOD) below 5 ppb at room temperature via a two-electrode response mechanism, addressing the stringent requirements of premium food quality control. To improve stability, an electrode passivation strategy was introduced to suppress the formation of inactive sulfate deposits, extending repeatability from 22 to 66 cycles (change rate within 10%). Replacing Cu-MOF with CuO, its stability significantly improved after passivation, confirming the strategy’s general applicability. We further developed a portable H 2 S monitoring system capable of real-time freshness tracking, showing a strong correlation with early spoilage. This work demonstrates a generalizable stabilization strategy for mixed-potential type H 2 S sensors and provides a practical, non-destructive platform for freshness grading in premium food supply chains.

Bacillus subtilis (BS) effectively suppresses soilborne pathogens and enhances crop resistance through various mechanisms. However, its efficacy is significantly influenced by effective inter-root colonization rates, among other factors, necessitating precise quantitative monitoring for optimal application. Conventional detection methods are often time-consuming and technically demanding, limiting their application in the field. To address this challenge, we developed a dual-recognition biosensing platform. Specifically, tridentate-functionalized aptamer was utilized for rapid BS enrichment and secondary recognition achieved using fragment crystallizable mannose-binding lectin (FcMBL)-modified nanozyme (MOF-818). The rigid scaffold of MOF-818 ensured superior catechol oxidase activity and environmental stability, facilitating sensitive and robust online quantification of BS in complex soil matrices. The linear detection range of the platform was 10 2 –10 7 CFU/mL, and the detection limit was 12 CFU/mL. This work provides a reliable tool for real-time monitoring of BS in agricultural systems, facilitating its efficient use in biocontrol and soil health management. Graphical
