We herein report that the morphology, size, and surface charge status of MIL-100(Fe) micro/nanoparticles can be tailored by adding a coordination modulator (HF or tetramethylammonium hydroxide) to the reaction system. Interestingly, the adsorption capacities of low-crystallinity MIL-100(Fe) and MIL-100(Fe)-TMA toward Congo red (CR) and acid chrome blue K (AC) were found to be significantly larger than that of the high-crystallinity MIL-100(Fe)-HF adsorbent, whereas there was little difference in the adsorption capacities of the three MIL-100(Fe) toward methyl orange (MO) and methylene blue (MB). The adsorption uptake of MIL-100-(Fe)-TMA toward the anionic dyes (CR, AC, and MO) was found to be highest, whereas the adsorption uptake of MIL-100(Fe) toward the cationic dye (MB) was the highest owing to different adsorption mechanisms. This adsorption behavior could be rationalized based on the morphological characteristics and crystal structure defects, zeta potential, and pore volume of MIL-100(Fe) and the adsorption characteristics and molecular structure of the dye. It was revealed that the adsorption performance of MIL-100(Fe) micro/nanoparticles is governed by the synergistic interplay between electrostatic, hydrophobic, and π–π stacking interactions, pore volume, crystal structure defects, and steric hindrance of the adsorbent.

In this work, a magnetic metal–organic framework designated as MIL-100(Fe) was prepared and applied as a magnetic solid-phase extraction sorbent for the determination of trace polycyclic aromatic hydrocarbons in environmental water samples by coupling with high-performance liquid chromatography and fluorescence detection. The magnetic microspheres exhibited large surface areas and high extraction ability, making them excellent candidates as sorbents for enrichment of trace polycyclic aromatic hydrocarbons. Under the optimized experimental conditions, good sensitivity levels were achieved with low detection limits ranging from 32 to 2110 pg/mL and good linearities with correlation coefficients higher than 0.9990 for the investigated 13 polycyclic aromatic hydrocarbons. The proposed method has been validated in the analysis of real water samples with mean recoveries in the range of 81.4–126.9% at four spiked levels and the relative standard deviations in the range of 1.3–17.0%. The magnetic MIL-100(Fe) microspheres were stable enough for 150 extractions without a significant loss of extraction performance.

Polydimethylsiloxane (PDMS)/MIL-100(Fe) coated stir bar was prepared by sol gel technique, and good preparation reproducibility was achieved with relative standard deviations (RSDs) ranging from 2.6% to 7.5% (n=7) and 3.6% to 10.8% (n=7) for bar-to-bar and batch-to-batch, respectively. Compared with commercial PDMS coated stir bar (Gerstel) and PEG coated stir bar (Gerstel), the prepared PDMS/MIL-100(Fe) stir bar showed better extraction efficiency for target triazines compounds. It also exhibited relatively fast extraction/desorption kinetics and long lifespan. Based on it, a method of PDMS/MIL-100(Fe) coated stir bar sorptive extraction (SBSE)-high performance liquid chromatography-ultraviolet detector (HPLC-UV) was developed for the determination of six triazines (simazine, atrazine , prometon , ametryn , prometryne and prebane) in environmental water samples. Several parameters affecting SBSE of six target triazines including extraction time, stirring rate, sample pH, ionic strength , desorption solvent and desorption time were investigated. Under the optimal experimental conditions, the limits of detection (LODs, S/N=3) were found to be in the range of 0.021–0.079 μg L −1 . The repeatability RSDs were in the range of 2.3–6.3% (n=7, c=0.5 μg L −1 ) and the enrichment factors (EFs) ranged from 51.1 to 102-fold (theoretical EF was 200-fold). The proposed method was applied to the analysis of target triazines in environmental water samples, with recoveries of 98.0–118% and 94.0–107% for spiked East Lake water and local pond water samples, respectively.

Zearalenone (ZEN), a mycotoxin produced by fungi of the genus Fusarium , is widely present in animal feeds and human foods, posing a serious hazard to human health. Herein, a zearalenone aptamer-functionalized magnetic metal-organic framework material (ZEN-Apt@MMIL-100(Fe)) was constructed and applied for the rapid enrichment of ZEN, coupled with high-performance liquid chromatography (HPLC) for ultrasensitive detection. By a self-templating method, magnetic MIL-100(Fe) was formed by self-assembly of sodium citrate-modified Fe 3 O 4 particles as nuclei with homobenzoic acid, which was bonded to amino-modified zearalenone nucleic acid aptamer via amide reaction to realize a specific recognition function. The magnetic dispersive solid-phase extraction and HPLC method was established using this material, with the linear range of 5 to 200 μg/L ( R 2 = 0 . 997) and the limit of detection of 2.92 μg/L. The method was applied to detect ZEN in maize and wheat samples, with spiked recoveries ranging from 81.7% to 98.2% at spiking levels of 25 μg/L, 50 μg/L, and 100 μg/L. The method is able to realize the selective and rapid enrichment and detection of trace ZEN in wheat and maize through the synergistic action of aptamer-specific recognition and magnetic MOFs, which provides a sensitive and reliable analytical strategy for food security monitoring.

Colorectal cancer (CRC) remains a major global health burden as the third most commonly diagnosed malignancy and the second leading cause of cancer-related mortality worldwide. While combination chemotherapy and immune agonists hold potential to overcome tumor heterogeneity through multi-pathway modulation, their therapeutic efficacy remains limited by off-target drug distribution and immunosuppressive tumor microenvironment (TME). To address this, we developed a tumor-targeted chemo-immunotherapy platform by encapsulating irinotecan (CPT-11) and resiquimod (R848) in hyaluronic acid (HA) coated MIL-100(Fe) metal-organic frameworks (CRMH NPs), enabling CD44-mediated delivery and synergistic anti-tumor responses. The system enabled controlled drug release in the acidic TME, promoting immunogenic cell death (ICD), inducing the cGAS-STING pathway and activating immune cells. In vitro , CRMH NPs induced significant ICD, as evidenced by the release of damage-associated molecular patterns (DAMPs) like high mobility group box 1 (HMGB1) and calreticulin (CRT), and matured dendritic cells (DCs), which triggered by TLR7 agonist, enhancing immune responses. It also activated the cGAS-STING pathway, which could efficiently induce the targeted cells to produce type I interferon (IFN) and proinflammatory cytokines, thereby enhancing T cell activation and recruitment. In vivo , CRMH NPs significantly reduced tumor growth in CT26 mouse models, activated innate immune signaling, and increased immune cell infiltration, demonstrating superior anti-tumor effects compared to free drugs and other nanoparticle formulations. Furthermore, CRMH NPs upregulated PD-L1 expression on tumor cells, suggesting potential synergy with immune checkpoint blockade therapy. Combining CRMH NPs with anti-PD-L1 therapy enhanced anti-tumor immunity, particularly in distant tumors, highlighting a promising approach to overcoming immune evasion and achieving durable tumor regression. These findings supported CRMH NPs as a versatile and effective platform for chemo-immunotherapy in CRC. Statement of Significance Colorectal cancer (CRC) remains a major global health challenge with limited treatment efficacy due to tumor heterogeneity and immunosuppression. This study introduces a novel tumor-targeted nanoparticle platform, CRMH NPs, which co-deliver the chemotherapeutic drug irinotecan (CPT-11) and the immune agonist resiquimod (R848) using hyaluronic acid-coated MIL-100(Fe) metal-organic frameworks. CRMH NPs enhance drug delivery, induce immunogenic cell death, and activate the cGAS-STING pathway, synergizing chemotherapy and immunotherapy. Demonstrating superior tumor suppression and immune activation in preclinical models, this platform overcomes key limitations of current therapies, such as off-target effects and immune evasion. Its combination with anti-PD-L1 therapy further improves outcomes, offering a promising strategy for durable CRC treatment. This work advances nanomedicine and immuno-oncology, providing a transformative approach for cancer therapy.

Catalytic tar reforming is a pivotal technology for upgrading syngas quality during sewage sludge gasification. In this study, a series of Ni-modified carbon-based catalysts (x%NiFe/C) were synthesized using MIL-100(Fe) as a precursor to investigate the impact of Ni-loading on the catalytic performance for tar reforming. Detailed characterizations, including XRD, XPS, Raman, and NH 3 -TPD, revealed that the introduction of Ni species significantly tailored the physicochemical properties of the catalysts. Specifically, the 3.3%NiFe/C catalyst exhibited the optimal specific surface area and pore structure, facilitating efficient mass transfer. Characterization results confirmed the formation of Ni-Fe alloy, which not only modulated the surface electronic density to optimize acidity but also enhanced the dispersion of active sites. The interaction between Ni and Fe species effectively promoted the cleavage of C-C and C-H bonds in tar molecules while suppressing carbon deposition. Consequently, the 3.3%NiFe/C catalyst demonstrated superior catalytic activity and stability in the two-stage microwave-assisted gasification reforming process, achieving a syngas yield of 555 mg/g·SS, a tar conversion rate of 82.9%, and an H 2 concentration of 73.8 vol%. After ten cycles, the H 2 yield and concentration remained as high as 28.0 mmol/g·SS and 68.2 vol%, respectively. This work provides mechanistic insights into the design of MOF-derived carbon-supported catalysts for efficient SS gasification.

Concerns about food safety have been arisen due to the improper use of chemicals in aquaculture. Malachite green (MG) has attracted attention because of its illegal usage and its potential negative impacts on the environment and public health. Surface-enhanced Raman scattering (SERS) platforms coupled with different SERS substrates have been employed for rapid analysis of MG residues in food. However, the most commonly used SERS substrates were non-reusable and showed limited detection sensitivity. In this study, a novel SERS substrate with a good recyclability and a high sensitivity was prepared by electrostatically assembling together a metal–organic framework material called materials of institute lavoisie-100(Fe) (MIL-100(Fe)) and Au NPs. The lowest detectable concentration of MG was 10 −13 M based on the optimal substrate. The SERS sensor was applied for the detection of the trace MG in fish pond water, which was accomplished with the correlation coefficients R 2 = 0.991–0.996 in a concentration range of 10 −6 –10 −13 M. Moreover, MIL-100(Fe)/Au was recycled at least five times, realizing a “detection to degradation”, showing great potential for food contamination monitoring due to its distinguished performance.

A novel multifunctional Janus magnetic micromotor was designed and constructed by using MIL-100(Fe)@TiO2@Fe3O4 multicore–shells modified with horseradish peroxidase (HRP) as a smart active platform to realize detection and degradation of hydroquinone (HQ). The obtained micromotor showed a unique three-dimensional (3D) hierarchical architecture with highly exposed active sites and could autonomously move at a speed of 140 ± 7.0 μm·s–1 by O2 bubbles generated from the catalytic decomposition of H2O2 fuel. Benefiting from the combination of active self-propulsive motion, high peroxidase-like activity, tuned heterojunctions with matching band structures, and a 3D hierarchical structure, an effective platform involving dynamically sensitive detection and quick removal of HQ from water was established by using the multifunctional HRP-integrated MIL-100(Fe)@TiO2@Fe3O4 Janus micromotor. The proposed multifunctional Janus magnetic micromotor had advantages of simple and feasible fabrication, sensitive detection and effective photo-Fenton degradation of HQ in a wide pH range of 4–7, and magnetic recycling, revealing potential for environmental remediation applications.

Building materials with the dual function of temperature and humidity regulation can improve people's living comfort and reduce energy consumption. In this work, a simple and convenient strategy for building a comfortable indoor temperature and humidity environment was proposed. The phase change humidity control material (PCHCM) was prepared by the mixing of form-stable composite phase change material (CPCM) as temperature-control component and hygroscopic MIL-100(Fe) as humidity-control component. In PCHCM, the CPCM was obtained by molten recombination of myristic acid, tetradecanol, and capric acid (MA-TD-CA) as phase change material and hydrophilic fumed silica (SiO 2 ) as porous carrier, and MIL-100(Fe) was synthesized by low-temperature solution method. Thermal analysis indicated that, under the optimized mass ratio of 28.8%MA-61.2%TD-10%CA, the CPCM containing 30 % SiO 2 could effectively prevent the leakage of ternary eutectic , with a suitable phase change temperature and enthalpy (21.74 °C, 96.70 J·g −1 ). The thermal and wet performance evaluation confirmed that the PCHCMs containing 40–50 % CPCM had human body comfortable phase change temperature (26.96–27.26 °C) and high saturation adsorption capacity (0.179–0.205 g/g) at 60 % RH as well as outstanding thermal and wet cycle reliability, indicating the novel MA-TD-CA/SiO 2 /MIL-100(Fe) PCHCM has broad application potential in room temperature and humidity control and building energy conservation .

A novel colorimetric aptasensor assay based on the excellent magnetic responsiveness and oxidase-like activity of Fe 3 O 4 @MIL-100(Fe) was developed. Fe 3 O 4 @MIL-100(Fe) absorbed with aptamer and blocked by BSA served as capture probe for selective isolation and enrichment of Listeria monocytogenes one of the most common and dangerous foodborne pathogenic bacteria. The aptamer absorbed on Fe 3 O 4 @MIL-100(Fe) was further used as signal probe that specifically binds with target bacteria conjugation of capture probe for colorimetric detection of Listeria monocytogenes , taking advantages of its oxidase-like activity. The linear range of the detection of Listeria monocytogenes was from 10 2 to 10 7 CFU mL −1 , with the limit of detection as low as 14 CFU mL −1 . The approach also showed good feasibility for detection of Listeria monocytogenes in milk and meat samples. The spiked recoveries were in the range 81–114% with relative standard deviations ranging from 1.28 to 5.19%. Thus, this work provides an efficient, convenient, and practical tool for selective isolation and colorimetric detection of Listeria monocytogenes in food. Graphical Abstract

The release and dispersion of uranium during mining activities and fuel/waste management processes in nuclear power plants pose serious environmental risks, particularly in aqueous systems. In such environments, uranium exhibits high solubility and strong mobility, leading to severe radioactive contamination of groundwater, soil, and ecosystems. Therefore, remediating uranium-contaminated environments remains a significant scientific and technological challenge. To address this issue, the present study exploits the high specific surface area and tunable pore architectures/functional sites of metal-organic frameworks (MOFs). Using a controlled synthesis strategy, a core-shell (Fe-Ni) galvanic cell structure was constructed and integrated with MIL-100(Fe) to fabricate the Ni-Fe-MIL-100(Fe) composite, enabling highly efficient and synergistic removal of U(VI) via an “adsorption-reduction-complexation” mechanism. Experimental results demonstrate that the maximum uranium uptake capacity reached 3038.19 mg·g −1 at 303 K and pH = 5, with a significantly enhanced removal efficiency. The kinetic analysis indicates that the uranium adsorption process is well described by the pseudo-second-order model. Combined with density functional theory (DFT) calculations, the electronic transfer channels of the structure were elucidated, revealing that they drive the reduction of U(VI) and facilitate its coordination and immobilization at multi-metal and oxygen-containing sites. These findings confirm that U(VI) removal by the composite material proceeds via a coupled chemical reduction and complexation process, thereby clarifying the underlying adsorption mechanism. Moreover, in mixed-ion solutions and real seawater, the composite maintains high adsorption capacity and excellent selectivity, demonstrating strong potential for uranium immobilization and recovery in the remediation of radioactive wastewater.

MIL-100(Fe) was successfully synthesized at room temperature and incorporated in bilayer film matrix. • MOFs and betalain generate molecular interactions within the film matrix as a filler. • Active films exhibited strong barrier, antioxidant and antibacterial properties. • These films prolonged the shelf life of beef and can be used for beef freshness monitoring. • This study offers novel insights into the development of active, smart food packaging. Meat is prone to microbial spoilage and faces significant risks from foodborne illnesses. This study introduces an innovative approach utilizing metallic organic frameworks (MOFs) as antibacterial agents and beetroot extract (BTE) for pH sensitivity to address existing challenges. Furthermore, this study utilized tri-polymeric concept via protein-polysaccharide combination, which includes sodium alginate to stabilize betalain, and gelatin and chitosan to give strong mechanical properties. The MOFs were synthesized using green synthesis, confirmed through structural and multispectral analysis. Betalain extracted from beetroot was incorporated into these tri-polymeric films. The developed films demonstrated excellent antioxidant and antibacterial properties. Furthermore, the pH sensitivity of betalain renders these films suitable for use as biosensors, with the quality stage of beef successfully assessed. Moreover, the films exhibited strong UV, water, and oxygen barrier properties. Atomic force microscopy revealed differences in surface morphology, with a uniform distribution, and films showed high mechanical strength. Concurrently, the addition of MOFs and BTE extract potentially extended the shelf life of beef by up to three days compared to control tri-polymeric films. These multifunctional films present new strategies employing novel antibacterial materials and tri-polymeric combinations which can efficiently preserve beef quality, while BTE indicates spoilage in real time.
