Novel dual sustained-release film with antioxidant/antibacterial synergy. • PACS grafting enables persistent antioxidant activity. • CV@ZIF-8 nanoparticles provide prolonged antibacterial release. • Enhanced barrier, mechanical and UV-shielding properties. • Effectively preserves strawberry quality and extends shelf life. Few bio-based active packaging films simultaneously achieve sustained antioxidant and antibacterial functions, making a dual sustained-release system highly desirable. To extend postharvest fruit shelf life, this study developed an active packaging film based on konjac glucomannan (KGM). A dual-release antioxidant and antibacterial system was constructed by introducing proanthocyanidin-grafted chitosan (PACS) and carvacrol-loaded ZIF-8 nanoparticles (CV@ZIF-8). The resulting KPCZ-3 film exhibited a tensile strength of 34.36 MPa, a water vapor permeability of 2.72 g·mm·m −2 ·day −1 ·kPa, and an oxygen permeability of 1.27 × 10 −3 g·s −1 ·m −2 . In strawberry preservation tests at 25 °C, the film synergistically delayed quality deterioration and maintained optimal sensory and nutritional quality for over 4 days. In addition, the film showed good biodegradability and biocompatibility. These results indicate that KGM/PACS/CV@ZIF-8 films, as novel degradable active packaging, have promising application prospects.

Magnesium-metal organic batteries (MMOBs) combine high charge-storage capacity with resource abundance and favorable material economics. However, their application is limited by dissolved organic shuttle and separator issues, including thick, costly glass fiber (GF) separators and poor coating adhesion on commercial separators. Herein, we report a rationally designed ZIF-67@polypropylene (PP) separator, fabricated via a robust in situ nucleation strategy that yields a dense, binder-free, and conformal MOF layer on both faces of a commercial substrate. Compared with conventional coating, this in situ modification strategy not only suppresses shuttle and improves wettability, but also strengthens interfacial bonding, enhancing mechanical robustness and durability. Benefiting from well-defined pores, ZIF-67 acts as an ion sieve that effectively suppresses anthraquinone (AQ) dissolution/shuttle while facilitating Mg 2+ transport and accelerating redox kinetics. Consequently, symmetric Mg||Mg cells employing this modified separator deliver an extended lifespan exceeding 1300 h with a mere ∼90 mV overpotential at 0.05 mA cm −2 . More impressively, Mg||AQ full cells demonstrate exceptional durability, retaining a reversible capacity of 94.5 mAh g −1 after 250 cycles at 0.1 A g −1 . This work highlights the critical role of in-situ separator modification in unlocking the full potential of sustainable MMOBs.

Volatile amines generated during meat spoilage provide direct chemical signals for freshness evaluation, but rapidly translating these signals into stable visual responses remains a challenge. Herein, a rapid colorimetric indicator film was developed by incorporating sodium lignosulfonate-regulated ZIF-67 (ZIF-67@SLS) into a sodium carboxymethyl cellulose/pectin (CP) matrix. Modification with SLS endows ZIF-67 with a surface that exhibits greater affinity for amine compounds, thereby enabling it to interact more efficiently with volatile amines associated with meat spoilage. After integration into the CP matrix, CP/ZIF-67@SLS-5% achieved a ΔE of 19.72 after 10 min of NH 3 exposure, representing an 83.8% increase compared to CP/ZIF-67 (ΔE = 10.73), indicating a faster and stronger ammonia-responsive color transition. Meanwhile, the CP/ZIF-67@SLS-5% film maintained good color stability during 21 days of storage at 4, 25, and 50 °C, with ΔE values remaining below 5. The optimized CP/ZIF-67@SLS-5% film also exhibited improved mechanical and barrier performance, with tensile strength and elongation at break reaching 6.49 ± 0.08 MPa and 46.10 ± 2.04%, respectively, and water vapor transmission rate decreasing to 767.71 g m −2 d −1 . When applied to pork freshness monitoring at 4 and 25 °C, the CP/ZIF-67@SLS-5% film displayed visible color transitions from pale purple to brown during storage, enabling timely visual indication of pork spoilage. This work demonstrates that SLS-regulated ZIF-67 can serve as a response-active colorimetric unit for developing rapid ammonia-responsive indicators toward meat freshness monitoring.

The widespread accumulation of Congo red (CR) in industrial wastewater poses severe ecological and health risks due to its carcinogenicity and environmental persistence. Exploring the detection and adsorption strategy of CR is crucial for ensuring public health and protecting the environment. In this work, a magnetic composite named MMWCNTs@CDs@ZIF-8 was developed as a dual-functional sensing platform for precise quantitative detection and efficient adsorption of CR. MMWCNTs@CDs@ZIF-8 exhibited a linear range from 0.25 to 5 μM, and demonstrated low limit of detection (17.46 nM) and rapid response (4 min). Furthermore, it exhibited superior selectivity and anti-interference performance, making it suitable for environmental water samples analysis, with satisfactory recoveries and low relative standard deviations. The underlying detection mechanism was attributed to be internal filtration effect. Additionally, the adsorption performance of MMWCNTs@CDs@ZIF-8 was explored, and the maximum adsorption capacity was 131.84 mg g −1 , which demonstrated promising potential as an effective adsorbent for CR removal. Therefore, the proposal of MMWCNTs@CDs@ZIF-8) enables dual detection-decontamination functionality, providing innovative insights into constructing a versatile dual-functional sensing platform.

The efficient and effective removal of mixed pollutants from wastewater is of paramount importance for environmental remediation, given the diverse nature of contaminants present. In particular, arsenic (As) and ciprofloxacin (CIP) contamination in surface water has become increasingly severe. To address this challenge, this study synthesizes ZIF-67 and integrates it with the Fenton reaction to remove mixed As(III) and CIP pollutants from wastewater. Comprehensive characterization of ZIF-67 was conducted using FTIR, XRD, SEM, and BET analyses, as well as pHpzc measurements. As an efficient adsorbent, ZIF-67 offers a high surface area (1614 m²/g) and excels in removing pharmaceutical contaminants. A systematic investigation was conducted to evaluate the influence of key reaction parameters-including pH, H2O2/Fe2+ ratio, reaction temperature, adsorbent dosage, and reaction time-on pollutant removal efficiency, ultimately determining the optimal reaction conditions. The removal of As(III) and CIP follows a pseudo-second-order kinetic model and fits the Langmuir isotherm. Experimental results demonstrated that the maximum removal efficiencies for As(III) and CIP reached 98.07% and 99.96%, respectively, when ZIF-67 was coupled with the Fenton reaction. Mechanism studies indicate that during the coupling process, the Fenton reaction generates highly reactive hydroxyl radicals (•OH). These hydroxyl radicals (•OH) can oxidize trivalent arsenic and CIP into pentavalent arsenic and intermediate products, which are more easily adsorbed by ZIF-67, thereby enhancing the adsorption efficiency of ZIF-67 for pollutants. By leveraging the synergy of ZIF-67 and the Fenton reaction, this study proposes a promising strategy for enhanced As(III) and CIP removal, offering novel methods for wastewater treatment.

Rapamycin (RAPA) is widely used in biomedical applications due to its antitumor, autoimmune disease and neuroprotective effects. However, direct administration of RAPA may lead to side effects such as excessive suppression of the immune system, severe infections and increased risk of tumors. Zeolitic imidazolate framework-8 (ZIF-8) is one of the most promising MOFs that shows great potential in the field of drug delivery. In this study, we successfully prepared nano-ZIF-8 particles of uniform size and monodispersity by optimizing the reaction time, stirring time, and reactant concentration. ZIF-8 was used as a carrier loaded with RAPA (ZIF-8@RAPA), which was characterized by XRD, FTIR, UV vis, TGA, and zeta potential, and the results revealed that ZIF-8@RAPA with a dodecahedral morphology, a particle size of 82 nm ± 4.7 nm, and a drug-loading rate of up to 11.53 % was successfully synthesized and that the loaded RAPA could achieve long-lasting slow release. Furthermore, we monitored the structural evolution of ZIF-8@RAPA in PBS. We found that the structural stability of ZIF-8@RAPA could be maintained for up to 6 weeks, followed by the gradual cleavage and disintegration of the crystal structure, and the reformation of micro-crystals (dia(Zn)) at 8 weeks, which is presumed to be affected by the [HPO 4 ] 2- in the PBS solution. In addition, the biocompatibility of the ZIF-8@RAPA delivery system was comprehensively evaluated using macrophage RAW 264.7 and the zebrafish embryo model. The results revealed that the biotoxicity of ZIF-8@RAPA was concentration dependent and that it had good biocompatibility when it was applied at concentrations lower than 100 μg/mL. In summary, our study preliminarily elucidated the in vitro disintegration and reconstruction mechanisms of nano-ZIF-8@RAPA crystals and demonstrated their feasibility for application in biomedical fields.

This work focused on improving the pervaporation performance of Pebax® 2533 membranes cast on polytetrafluoroethylene substrates, by incorporating home-made bifunctionalized ZIF-L with amino groups and aromatic rings, to prepare MMMs for dephenolization from the aqueous solution. Amino groups in ZIF-L-NH 2 led to the enhanced interaction between the fillers and the matrix by forming hydrogen bonds, thus aminated fillers dispersed more homogeneously in MMMs than the non-aminated fillers and the MMMs possessed a better interface structure. Aromatic rings in ZIF-L-NH 2 made the membranes more organophilic and brought them a stronger affinity towards phenol. The separation performance of the MMM with 15 wt% fillers and 20 μm thickness surpassed most of the other phenol-selective membranes with the separation factor of 59.79 and the total flux of 1.93 kg/m 2 ·h for 1000 ppm phenol solution at 80 ℃. Notably, the MMMs maintained a good separation performance even when the phenol concentration of the feed solution extended to 18,000 ppm. In a 60 h long-term pervaporation, the MMM was stable. We believe that such MMMs design based on fillers with a ligand rich in aromatic rings and amino groups is a promising approach for high-performance dephenolization membranes.

The tumor microenvironment (TME), characterized by hypoxia, limited H 2 O 2 availability, and elevated glutathione (GSH) concentrations, challenges reactive oxygen species (ROS)-based therapies. To address these, we developed a GOx@Cu-ZIF-8/DOX (GCZD) nanoplatform combining chemotherapy (CT), chemodynamic therapy (CDT), and starvation therapy (ST). This system utilizes Cu-incorporated ZIF-8 (Cu-ZIF-8) as a versatile carrier to load glucose oxidase (GOx) and doxorubicin (DOX). Under acidic TME conditions, GCZD disintegrates, releasing GOx, Cu 2+ , and DOX. GOx catalyzes intratumoral glucose oxidation, producing gluconic acid and H 2 O 2 to achieve a triple-therapeutic effect. Gluconic acid maintains a weakly acidic environment for continuous GCZD degradation. Glucose depletion induces metabolic starvation. Generated H₂O₂ serves as substrate for Cu 2+ -mediated Fenton-like reactions, boosting ROS production. Cu 2+ exhibits catalytic activity, efficiently converting TME and GOx-generated H 2 O 2 into cytotoxic ·OH. Increased ROS concentration enhances biological macromolecule oxidation damage, intensifying CDT. Additionally, Cu 2+ oxidizes GSH to form GSSH and Cu + . This inhibits GSH-mediated ROS degradation and leverages excellent Fenton-like activity of Cu + to further enhance CDT. Simultaneously, DOX exerts chemotherapeutic effects by intercalating into DNA and inhibiting topoisomerase II, blocking tumor cell proliferation. This integrated approach, combining enhanced ROS generation, tumor cell metabolic intervention, and DNA damage, demonstrates enhanced antitumor efficacy by simultaneously targeting multiple cancer cell vulnerabilities.

The abnormal expression of monoamine oxidase B (MAO-B) and the soluble oligomer (Aβo) formed by β-amyloid deposition play key roles in the pathogenesis of Alzheimer’s disease. However, the simultaneous detection of MAO-B and Aβo remains a huge challenge. Herein, a bimetallic core–shell probe ZIF-8 embedding rhodamine 6G (Au/Rh6G/Pd@ZIF-8) with peroxidase-like activity is designed to detect MAO-B and Aβo simultaneously. MAO-B catalyzes the substrate phenethylamine (PEA) to produce H2O2, which oxidizes thiamine with the catalysis of Au/Rh6G/Pd@ZIF-8 to produce a fluorescent product that emits a strong fluorescence at 440 nm. When Aβo is present in the system, due to the specific coordination between Aβo and Zn2+, the intact ZIF-8 structure collapses, leading to Rh6G release and fluorescence recovery. The simultaneous determination of MAO-B and Aβo by Au/Rh6G/Pd@ZIF-8 is realized. The results showed that the designed biosensor had high specificity and sensitivity, a wide detection range, and a low detection limit for MAO-B and Aβo simultaneous detection. Fluorescence signals for MAO-B and Aβo detection did not interfere with each other because they are excited separately, which provides more valuable data for the diagnosis of Alzheimer’s disease.

Heavy metal ion pollution in wastewater, particularly Cu 2+ contamination, threatens ecology and human health, demanding efficient adsorption materials in environmental remediation. However, conventional adsorbents suffer from insufficient capacity, poor mechanical stability, weak selectivity, and low reusability, restricting their practical application. Herein, a semi-interpenetrating network composite hydrogel (ZIF-8-AVA) was fabricated via in situ self-assembly, integrating ZIF-8 nanocrystals into a poly(acrylamide- co -vinylimidazole)/sodium alginate (AVA) matrix. Vinylimidazole units served as nucleation anchors, firmly immobilizing ZIF-8 on the polymer backbone via metal-ligand coordination to form a stable system. ZIF-8 significantly enhanced AVA's mechanical properties and Cu 2+ adsorption performance: the composite followed the Langmuir monolayer adsorption model with a maximum adsorption capacity of 355.9 mg/g, achieving 93.81% Cu 2+ removal efficiency at an initial concentration of 50 mg/L. Furthermore, the ZIF-8-AVA hydrogel exhibited excellent selectivity for Cu 2+ in multi-competing-ion systems and maintained high adsorption efficiency after 5 consecutive adsorption-desorption cycles. The key innovation lies in the in situ self-assembly strategy that realizes the intimate integration of ZIF-8 with the hydrogel matrix via coordination-driven anchoring, overcoming the common issue of MOF particle leaching and synergistically enhancing adsorption capacity, selectivity, and mechanical stability. This work offers a novel approach for tunable MOF hydrogels, with great potential in heavy metal wastewater treatment.

Accurate detection of ammonia (NH 3 ) is a key indicator for evaluating the deterioration of high-protein foods and is of great significance for food safety. In this study, we modified Sn-ZnO using a Co-based metal–organic framework (MOF) material (ZIF-67) to prepare cauliflower-shaped Sn-ZnO/ZIF-67 (SZZ67) for NH 3 sensors at room temperature (25 °C). By regulating Co 2+ , it was found that the sensor's response to NH 3 decreased with the increase in Co 2+ content, while the desorption ability was significantly enhanced. When the mass ratio of Sn-ZnO to the added C 4 H 6 CoO 4 ∙4H 2 O was 1:1, its response was 13.46 times that of Sn-ZnO, the response/recovery time was 63.78/7.99 s, and good moisture resistance was observed. Density functional theory (DFT) confirmed that SZZ67 can adsorb more NH 3 and release more conductive electrons, thereby increasing its response value. The sensors prepared using SZZ67 could more effectively monitor NH 3 , which is applicable for monitoring the freshness of soy products.
