A ZnAg-ZIF@MPN nanopesticide was constructed via hierarchical MOF loading and metal–phenolic network encapsulation. • Metal node engineering significantly enhanced neonicotinoid pesticide loading capacity within ZIF microporous frameworks. • The MPN shell enabled pH-responsive release behavior and improved environmental stability under light exposure. • The hybrid nanoplatform exhibited enhanced foliar adhesion and rainfall resistance, reducing pesticide loss. • The system achieved improved insecticidal efficacy and lower final residue with favorable crop safety. Zeolitic imidazolate frameworks (ZIFs) emerge as promising pesticide delivery platforms due to their high porosity, structural tunability, and potential for stimuli-responsive release. However, their practical application is still constrained by limited loading capacity, insufficient environmental stability, and poor foliar retention under field conditions. Herein, a hierarchical nanopesticide system (ZnAg-ZIF/NIT@MPN) is constructed through a dual-engineering strategy combining bimetallic framework design and interfacial metal–phenolic network (MPN) coating. The incorporation of Zn 2+ and Ag + enables the formation of a stable ZIF matrix with enhanced pesticide loading capacity, which is further improved through parameter optimization. Subsequently, in situ deposition of a tannic acid (TA)-based MPN shell provides an additional functional interface for environmental regulation and delivery control. The resulting nanopesticide exhibits a confinement–interface synergistic mechanism, where the ZIF core ensures efficient pesticide encapsulation and structural stability, while the MPN shell regulates environmental responsiveness and interfacial interactions. This architecture significantly enhances photostability and enables pH-triggered release behavior, achieving rapid pesticide release under acidic conditions following first-order kinetics. In addition, ZnAg-ZIF/NIT@MPN shows improved wettability, foliar adhesion, and rainfastness, thereby reducing pesticide loss under environmental stress. Bioassays demonstrate markedly improved insecticidal efficacy against whiteflies with 95% mortality within 48 h, while maintaining favorable biosafety toward crop germination and early growth. Furthermore, residue analysis indicates reduced pesticide persistence at the harvest stage, while metal-leakage analysis reveals limited release of framework-derived Ag, Zn, and Fe species under the tested conditions. Overall, this work presents a hierarchical nanopesticide design strategy based on core–shell confinement and interfacial regulation synergy, offering a viable approach for improving pesticide efficiency, environmental stability, and agricultural safety in sustainable crop protection systems.

Nanozymes have attracted considerable attention as a promising class of artificial enzymes with significant development potential in recent years. Herein, a nitrogen-doped hollow porous carbon nanocomposite embedded with Co 3 O 4 nanoparticles (Co 3 O 4 -HPNC) was successfully synthesized through the controlled carbonization and subsequent slow oxidation of bimetallic Co/Zn zeolitic imidazolate frameworks (ZIFs). The Co 3 O 4 -HPNC features a hollow architecture conposed of numerous small nanoparticles, forming a porous flocculent morphology that enhances mass transport efficiency. It exhibited remarkable peroxidase-like activity, catalyzing the oxidation of colorless 3,3 ′ , 5,5 ′ -tetramethylbenzidine (TMB) to blue oxidized TMB (oxTMB) in the presence of H 2 O 2 . This reaction was driven by the generation of hydroxyl radicals (·OH), as confirmed by fluorescence and electron paramagnetic resonance (EPR) results. Notably, the oxidization process was significantly inhibited by the addition of L-cysteine (L-Cys), leading to a visible fading of the blue color and a corresponding decrease in UV–vis absorbance. Moreover, Co 3 O 4 -HPNC demonstrated good selectivity and strong anti-interference capability toward L-Cys detection. Based on these findings, a simple and effective colorimetric method was developed for quantifying L-Cys with a linear range of 1–50 μM and a detection limit of 0.13 μM (S/N = 3). This Co 3 O 4 -HPNC-based colorimetric platform holds significant potential for applications in biosensors and clinic diagnostics.

Growing needs for monitoring kanamycin (KAN) residues in food require ultrasensitive, field-deployable determination platforms. Herein, we present a universal photoelectrochemical (PEC) aptasensing strategy that synergizes ZIF-8/Bi 2 S 3 heterostructure-engineered photoelectrodes with strand displacement–triggered biocatalytic signal amplification. The urchin-like ZIF-8/Bi 2 S 3 heterojunction, synthesized through in situ MOF growth on semiconductor nanoarchitectures, demonstrates exceptional photocurrent generation via facilitated carrier separation achieved by directional electron transfer from Bi 2 S 3 to ZIF-8 and hole scavenging by ascorbic acid. Capitalizing on aptamer-target recognition in homogeneous phase, KAN concentration is transduced into messenger DNA (S2) through displacement dynamics, overcoming steric limitations of conventional solid-phase biosensing. The liberated S2 hybridizes with electrode-immobilized S1 to assemble MnPP-loaded dsDNA, where the mimic enzyme catalyzes H 2 O 2 -driven precipitation of benzo-4-chlorohexadienone (4-CD). This biocatalytic insulation layer induces quantifiable photocurrent attenuation proportional to KAN levels (10–1.0 × 10 6 nmol/L), achieving a 0.1 nM detection limit superior to ELISA and HPLC. The platform demonstrates 95.7–105.4% recovery in milk matrices and cross-reactivity below 5.8% against structural analogs, validating its specificity. By integrating MOF-semiconductor interfacial engineering with homogeneous-to-heterogeneous signal translation, this work establishes a paradigm for antibiotic monitoring that bridges laboratory innovation with on-site applicability.

The residue of acetamiprid (AAP) in agricultural products poses a threat to food safety. Traditional Surface-enhanced Raman scattering (SERS) detection faces issues such as complex and expensive substrate preparation, and the difficulty of effectively utilizing SERS hotspots due to random molecular diffusion at low concentrations, resulting in low detection sensitivity. Here, we introduced the highly adsorptive 2-Methylimidazole zinc salt (ZIF-8) and developed a portable, ultra-sensitive silver nanoparticle filter paper (FP) loaded with 2-Methylimidazole zinc salt (Ag@FP@ZIF-8) substrate. It was found that the enhancement factor (EF) value for Rhodamine 6G (R6G) when measured using a handheld Raman spectrometer was 1.401 × 10 13 . More importantly, after being kept in a sealed and dark environment at room temperature for 45 days, the signal retention rate remained at 92%. Additionally, it exhibits good uniformity, as evidenced by a relative standard deviation of less than 8.5%. Combining a handheld Raman spectrometer with the previously proposed capillary-assisted sampling method has enabled AAP to be extracted from apple, pear and Bok choy leaves in a shoNeed file 22165rt period of time. The detection limit for Bok choy is 0.01 mg/kg, meeting the requirements of the EU Commission's regulation (EU) 2025/158. This method is expected to be developed into a rapid, deployable solution for on-site pesticide screening.

The integration of inhibitor-encapsulated nanocontainers within organic coatings offers a viable approach for achieving sustained corrosion mitigation and extended protective functionality. In this study, a ZIF-8@LDH-P (ZLP) nanocontainer was developed, consisting of Ni-Co layered double hydroxide (LDH) derived from zeolitic imidazolate framework-8 (ZIF-8) precursors and incorporating trisodium phosphate (TSP) as a corrosion inhibitor. The release of phosphate ions from ZLP exhibited pH-responsive behavior, enabling triggered inhibitor release under corrosive conditions. When uniformly dispersed in the polyvinyl butyral (PVB) resin matrix and coated on Q235 carbon steel, the PVB/ZLP composite coating demonstrated an enhancement of two orders of magnitude in low-frequency impedance modulus (|Z| 0.01 Hz ) relative to pure PVB. Furthermore, the PVB/ZLP coating exhibited long-term protective capabilities, ascribed to the cooperative effect of regulated phosphate ions release for active corrosion inhibition, chloride ion entrapment by LDH interlayers, and the prolonged diffusion pathways for corrosive agents enabled by the lamellar structure of LDH. This study offers novel design strategies for ZIF-derived LDH nanocontainer-based anti-corrosion coatings with inhibitor loading.

Diabetic wound healing is a global biomedical challenge. Bacterial infection and microenvironmental modulation are major factors in the refractory healing of diabetic wounds. Conventional therapeutic approaches are often hindered by limitations, such as inadequate drug penetration, the rise of antimicrobial resistance, and restricted depth of drug delivery. Nanomedicine is emerging as a prospective drug delivery and anti-infective therapeutic approach in the field of wound management. Herein, all-trans retinoic acid (ATRA) was loaded into a zeolite imidazolate framework-91 salt+ (ZIF-91 salt+). A gelatin methacryloyl (GelMA) hydrogel microneedles (MNs) patch based on this multifunctional ZIFs (denoted as GelMA-ZIF-91 salt+@ATRA MNs patch) was developed, which makes transdermal drug delivery and combinatory treatment for diabetic wound healing feasible. Significantly, ATRA-containing ZIF-91 salt+ provides nanocomposites with anti-inflammatory activity through their modulation of macrophage polarization. Crucially, the prepared ZIF-91 salt+ showed efficient antibacterial activity against Staphylococcus aureus and Escherichia coli in vitro. Therapeutic effects of the GelMA-ZIF-91 salt+@ATRA MNs patch were verified in a diabetic mouse model with full-thickness cutaneous wounds. A unique MNs patch with antimicrobial, angiogenesis-inducing, and anti-inflammatory properties was designed in accordance with the physiological characteristics of wounds. Collectively, the designed MNs patch based on this multifunctional ZIF-91 salt+ provides new insights into diabetic wound therapy.

The mechanism for the NORR performance differences of varying Ni/Co ratios in Ni x Co y -LDH NF was revealed. • Ni 50 Co 50 -LDH NF can achieve a maximum NH 3 yield rate of 22.8 mg h −1 cm −2 with extremely low concentration NO. • We realized the efficient extraction and valorization of the produced ammonia. Utilizing electrocatalytic methods to efficiently convert harmful nitric oxide into derivatives of ammonia is undoubtedly a very economical way. Herein, we synthesized a series of different metal ratio Ni x Co y -layered double hydroxide nanoflower (Ni x Co y -LDH NF) material derived from the metal-organic framework (MOF), which can convert low concentration NO into ammonia. Among them, Ni 50 Co 50 -layered double hydroxide nanoflower can achieve a NH 3 yield rate of 4.33 mg h −1 cm −2 with a Faradaic efficiency of 74.6% in a H-cell. Notably, the yield can increase to 22.8 mg h −1 cm −2 at −0.4 V (V vs.RHE) with a current density over 250 mA cm −2 in a gas diffusion electrode. The post-electrolysis electrolyte was then collected and a membrane permeation device was used to purify the free ammonia into ammonium chloride. Our work investigated the influence of different proportions of Ni on the nitric oxide reduction reaction performance of layered double hydroxide materials and provided a new strategy for efficient NO conversion catalyst design.

The design and fabrication of high-efficiency, cost-effective multifunctional air nanofiber membranes are critically important for addressing the growing challenge of global particulate matter pollution. This study presents a structural optimization strategy based on the incorporation of porous functional nanoparticles to develop high-performance air filtration membranes. By precisely controlling the ZIF-67 loading ratio and spinning time, a hierarchical fiber network with a bimodal diameter distribution was constructed, enabling stable immobilization of the porous nanoparticles within the fibrous matrix. The resulting composite membrane achieved filtration efficiencies of 99.69% for PM 2.5 and 99.72% for PM 10 , with a low pressure drop of only 72 Pa. Its quality factor is 1.8 times higher than that of the pure PAN membranes. The membrane demonstrates excellent air permeability, UV resistance, and long-term stability. It maintains a filtration efficiency above 97.12% at a high flow rate of 50 L/min, with no noticeable performance decline after 30 days of continuous use. This fabrication method offers advantages such as simple operation, controllable processes, and scalability for mass production. The resulting composite membrane effectively balances filtration efficiency and breathability, making it a promising filter material for personal protective equipment and indoor air purification systems.

Defect-engineered Cu–TCPP/ZIF-L nanosheet membrane: tannic acid coordinates with Cu 2+ to create defect sites, while ZIF-L serves as an interlayer spacer to suppress π–π stacking and restore transport. • The optimized membrane achieves 691.20 L·m -2 ·h -1 ·bar -1 , a 75.5× increase over pristine Cu–TCPP. • Efficient dye removal under static conditions: 97.77% (CV) and 97.87% (MG), suitable for agricultural water purification. • Adsorption–degradation self-cleaning via single-layer chemisorption/ion exchange and catalytic oxidation by O₂· - / 1 O₂; cucumber seedling tests confirm irrigation safety. Dye-laden wastewater from aquaculture and agricultural runoff poses serious environmental challenges, calling for membranes that can deliver both high water flux and efficient dye removal. However, MOF-based composite membranes often still face trade-offs between permeance and separation efficiency, and their practical performance is limited by fouling and insufficient self-regeneration. We hypothesize that defect engineering of Cu–TCPP via tannic-acid-mediated metal–phenolic network (MPN) disruption, together with ZIF-L nanosheet interlayer modulation, can create favorable transport pathways and strengthen adsorption/ion-exchange interactions while enabling ROS-driven self-cleaning. A defect-engineered Cu–TCPP/ZIF-L nanosheet-modified PVDF membrane was prepared using an MPN strategy with tannic acid, and its dye removal performance toward malachite green and crystal violet, together with the underlying mechanisms, was systematically investigated. The optimized membrane achieves a 75.5-fold increase in water permeance to 691.20 L/(m 2 ·h·bar) while maintaining high removal efficiencies of 97.87% for malachite green and 97.77% for crystal violet, and it exhibits self-cleaning behavior enabled by superoxide radicals and singlet oxygen. This work demonstrates an integrated Cu-TCPP–TA/ZIF-L/PVDF membrane design that combines MPN-mediated defect regulation with ZIF-L-assisted lamellar structure modulation for adsorption–degradation-based dye removal in agricultural water-related scenarios.

In this work, HNTs@ZIF-67 composites were synthesized using the in situ growth method and incorporated into 6FDA-TFMB to prepare mixed-matrix membranes (MMMs). Scanning electron microscope (SEM) and transmission electron microscope (TEM) proved that the HNTs@ZIF-67 composite not only retained the hollow structure of HNTs, but also formed a continuous ZIF-67 transport layer on the surface of HNTs. The results of gas permeability experiments showed that with the increase in HNTs@ZIF-67 incorporation, the He permeability and He/CH4selectivity of MMMs showed a trend of increasing first and then decreasing. When the loading is 5 wt%, the He permeability and He/CH4selectivity of MMMs reach 116 Barrer and 305, which are 22.11% and 79.41% higher than the pure 6FDA-TFMB membrane. The results of density functional theory (DFT) and Monte Carlo (MC) calculations reveal that He diffuses more easily inside ZIF-67, HNTs and 6FDA-TFMB than CH4, and ZIF-67 shows larger adsorption energy with He than HNTs and 6FDA-TFMB, indicating that He is easily adsorbed by ZIF-67 in MMMs. Based on experimental and molecular simulation results, the mechanism of HNTs@ZIF-67 improving the He/CH4separation performance of MMMs was summarized. With the advantage of a smaller molecular kinetic diameter, He can diffuse through ZIF-67 on the tube orifice of HNTs@ZIF-67 and enter the HNTs’ hollow tube for rapid transmission. At the same time, He can also be rapidly transferred in the continuous ZIF-67 transport channel layer, which improves the He permeability and the He/CH4selectivity of MMMs.

As the CO2 concentration in the atmosphere is relatively low, directly capturing CO2 from the air remains a challenge. Herein, a dual-functionalized strategy is developed to construct a series of IL@ZIF-8 composite materials by regulating the spatial distribution of nitrogen sites of the anion and the amine content of the cation in the ionic liquid (IL). The introduction of functional sites significantly enhances the capture capability of composite materials toward low-concentration CO2. The IL composed of pyrazole (Py) with adjacent nitrogen sites exhibits stronger interaction with CO2 due to its lower viscosity and higher electron cloud density. The IL@ZIF-8 constructed with tetraethylenepentamine (TEPA) as the cation and Py demonstrates optimal CO2 capture capability, which is attributed to TEPA’s balance of abundant amine groups and moderate viscosity. [TEPA][Py]@ZIF-8 exhibits a remarkable dynamic CO2 capture capacity under simulated air conditions, and in situ FT-IR analysis reveals its reversible adsorption mechanism. This study provides a new strategy for the development of novel adsorbents for low-concentration CO2 capture.

Infected skin wound healing involves a series of dynamic and complex physiological processes. In this study, we reported a dissolvable microneedle (MN) with pullulan as the matrix material. The antimicrobial peptide LL37 was immobilized in situ within ZIF-8 to form hybrid nanoparticle LL37@ZIF-8 (LZ). This nanoparticle was then loaded onto the tip of the microneedle along with Prussian Blue (PB) nanozymes to obtain PB+LZ@MN, which exhibits both antimicrobial and antioxidative activities, for the healing of infected skin wounds. The MN, with good mechanical properties, could rapidly dissolve its tip upon insertion into the skin, releasing LZ and PB into the wound within 3 min. The MN had good physicochemical properties and biocompatibility and was shown to reduce inflammation and stimulate angiogenesis by enhancing collagen deposition and re-epithelialization in the Sprague-Dawley (SD) rat skin defect infection model. On the 10th day of wound healing, the healing rate of the PB+LZ@MN group was as high as 99%, which was significantly higher than that of the control at 84%, significantly accelerating the healing of the infected wound. This multifunctional MN is expected to provide a competitive biomaterial for accelerated infected wound healing.
