Gentamicin (GEN), an aminoglycoside antibiotic, is widely used in treating infections within the livestock industry but readily causes food residues and environmental pollution. This study developed a novel water-soluble supramolecular fluorescent probe DBTPy 2+ @Q[8], through host–guest interactions between the methylpyridine-modified benzothiophene cationic fluorophore (DBTPy 2+ ) and cucurbit[8]uril (Q[8]). This enabled specific GEN recognition and detection via the fluorescence indicator displacement (FID) mechanism. The DBTPy 2+ -Q[8] assembly induced significant fluorescence quenching, while GEN addition rapidly restored fluorescence. The restored intensity exhibited a good linear relationship with GEN concentration in the range of 0.1–10 μM (R 2 = 0.996), with a limit of detection (LOD) of 0.206 μM. The probe exhibited good selectivity and anti-interference capability, achieving 92.0%–104.1% spiked recoveries in water and food samples, and enabled specific GEN fluorescence imaging in living cells. This work establishes a novel supramolecular host–guest strategy for fluorescent probes enabling rapid, quantitative, specific GEN detection.

Poor interfacial stability and dendrite penetration at the lithium metal anode interface are critical bottlenecks hindering the practical application of garnet-type solid electrolytes, despite their high intrinsic ionic conductivity. Herein, we resolve this long-standing trade-off by designing a hierarchical sandwich heterostructure. This architecture comprises a dense Li 6.4 Ga 0.2 La 3 Zr 2 O 12 (C-LGLZO) ceramic scaffold sandwiched between two ZIF-8@SiO 2 /PVDF-HFP (ZSPH) composite interfacial layers. The resulting composite solid electrolyte (CSE) C-LGLZO/ZSPH exhibits exceptional electrochemical properties: a high Li + transference number (t Li+ = 0.77) and an outstanding ionic conductivity of 1.31 × 10 −3 S cm −1 at 30 °C. Mechanistically, while the robust central C-LGLZO scaffold provides a continuous Li + pathway and physically blocks dendrites, the honeycomb-like porous ZSPH interfacial layers homogenize the interfacial electric field and promote a stable solid electrolyte interphase (SEI). This synergistic design endows the CSE with a wide electrochemical stability window (4.8 V vs. Li/Li + ) and enables stable Li plating/stripping for over 1000 h. Furthermore, cells using a LiFePO 4 cathode retain 76.3 % of their capacity after 500 cycles at 0.5C, demonstrating exceptional high-rate cycling stability. This work offers a versatile architectural strategy for engineering robust solid-state batteries (SSBs).

Synergistic coating design combining ZIF-8 and PDMS on a porous PI substrate. • Integrated multifunctionality enabling oil-water separation, photocatalytic degradation, and anti-bioadhesion. • Exceptional separation performance with a water contact angle of 162.8° for various oil-water mixtures. • Outstanding environmental durability demonstrated against mechanical abrasion, UV aging, and acid/alkali corrosion. The treatment of wastewater containing oils and organic pollutants remains a critical environmental challenge. Traditional separation membranes often lack the multifunctionality needed for simultaneous separation, degradation, and antifouling. In this study, a robust superhydrophobic composite membrane was fabricated via a facile solution-impregnation method, in which zeolitic imidazolate framework-8 (ZIF-8) nanoparticles were integrated with polydimethylsiloxane (PDMS) onto a porous polyimide (PI) substrate. The designed coating synergistically combines the micro-/nano-scale roughness of ZIF-8 with the low surface energy of PDMS, endowing the membrane with a water contact angle of 162.8 ± 0.3° and a sliding angle of 3.0 ± 0.4°. The composite membrane demonstrates high-efficiency separation of various oil-water mixtures (>95% efficiency, flux >9000 L·m −2 ·h −1 ), effective photocatalytic degradation of methylene blue (MB) under ultraviolet (UV) light (93.7% within 2.5 h), and excellent anti-bioadhesion performance against Chlorella vulgaris. Moreover, the membrane retains its superhydrophobicity after mechanical abrasion, tape peeling, UV aging, and exposure to acidic/alkaline environments, confirming outstanding durability. This work presents a scalable strategy for developing multifunctional PI-based membranes with integrated separation, catalytic, and antifouling properties, showing promising potential for practical water remediation applications.

An adsorption-triggered mechanism was proposed for on-demand release. • Acidic sites on ZSM-5/ZIF-8 possess stronger adsorption energy for biogenic amines than CA. • The mechanical and gas barrier of film were improved after introducing ZSM-5/ZIF-8. • The developed packaging effectively prolonged fish preservation at 4 °C. Active packaging with on-demand release capability has attracted increasing interest in food preservation; however, the delayed response of active agents often compromises protection during the early stage of spoilage. In this work, an adsorption-triggered release strategy was proposed by incorporating cinnamaldehyde (CA)-loaded ZSM-5/ZIF-8 nanoparticles (CA@ZSM-5/ZIF-8) into a sodium alginate (SA) matrix. Owing to the strong affinity of biogenic amines toward the adsorption sites of ZSM-5/ZIF-8, low concentrations of histamine could competitively displace the preloaded CA, thereby enabling an early and responsive release behavior. In the absence of histamine, the cumulative release of CA from the composite film remained below 10% within 12 h, whereas it increased to approximately 60% in the presence of 5.0 mM histamine. Meanwhile, the optimized film exhibited improved tensile strength (54.6 MPa), water vapor barrier performance (0.86 × 10 −10 g·m·m −2 ·s −1 ·atm −1 ), UV-shielding capability, and water resistance. The film also showed pronounced antioxidant activity (91.4%), sustained antibacterial effects against E. coli and S. aureus , and favorable biodegradability. When applied to fish preservation, the optimized film effectively extended the refrigerated shelf life to 6 days at 4 °C. This study provides a novel paradigm for on-demand release in intelligent food packaging.

Natural antioxidants are limited in food packaging due to poor stability and compatibility. A multifunctional film was successfully prepared via the incorporation of functional fillers into a guar gum/polyvinyl alcohol (GP) matrix. ZIF-8 was amino-functionalized to enhance rutin (Rt) loading, and the resulting ZIF-8-NH2@Rt was combined with purple sweet potato anthocyanins (PSPA) to fabricate a composite film for pork freshness monitoring. Compared with neat GP, the ZIF-8-NH2@Rt/PSPA/GP film showed a 30.6% increase in tensile strength and an elongation at break of 36.6%. The composite film also imparted exceptional UV-blocking capabilities, with light transmittance plummeting to 3.22% in the UVA region, 0.40% in the UVB region, and 47.53% within the visible light spectrum. The films displayed significant antioxidant properties, with DPPH and ABTS scavenging activities recorded at 73.27% and 67.64%, respectively. During pork storage, the film exhibited stable color changes. The G/R values corresponding to the limit of edibility were determined to be 0.78 and 0.67 for storage at 25 °C and 4 °C, respectively. The film was reusable for four cycles and extended the shelf life of pork by at least one day. These findings highlight the film’s considerable promise in the realm of smart food packaging and dynamic freshness tracing.

Yolk-shell magnetic ZIF-8@MOF-74 was synthesized and utilized as a magnetic solid-phase extraction (MSPE) adsorbent for the detection of benzoylurea insecticides (BUs) residues in freshly-squeezed fruit and vegetable juices. The fabrication of magnetic ZIF-8@MOF-74 was conducted under mild and simple conditions without high-temperature/pressure or energy-intensive equipment. With a large specific surface area (880.78 m 2 g −1 ) providing abundant adsorption sites, the mesoporous architecture (average pore size 2.57 nm) and yolk-shell structure of magnetic ZIF-8@MOF-74 enable efficient mass transfer, achieving equilibrium within 7 min as an MSPE adsorbent for BUs. The established analytical method demonstrates good linearity in the concentration range of 0.5–200 μg L −1 , with low limit of detection (LOD) between 0.1 and 0.3 μg L −1 . The recoveries of BUs in freshly-squeezed pear juice and tomato juice samples were in the range of 81%–114% and 102%–120%, respectively. Evaluation via the ComplexGAPI index confirms its environmental sustainability. Download: Download high-res image (118KB) Download: Download full-size image

A major bottleneck in radio-immunotherapy is the inability to precisely couple the localized stimulus of radiotherapy (RT) with the systemic action of immunotherapeutics. To bridge this gap, we developed a chemically engineered RT-ignited nanoplatform that productively harnesses the biochemical consequences of RT to precisely activate immunotherapy locally, thereby amplifying its benefits while minimizing systemic exposure. The platform co-delivers a hydrogen sulfide (H₂S)-responsive prodrug of toll-like Toll-like receptor 7/8 (TLR7/8) agonist imiquimod (IMQ) using a reactive oxygen species (ROS)-sensitive, targeted nanocarrier. RT ignites a biochemical sequence: ROS bursts disassemble the carrier, and the subsequent H₂S upregulation cleaves the prodrug, ensuring tumor-localized drug release. This RT-primed, sequentially activated therapy profoundly enhances antitumor immunity by inducing immunogenic cell death (ICD), activating antigen-presenting cells (APCs), and overcoming systemic immunosuppression, culminating in durable tumor regression and immunological memory. This study highlights a chemistry-driven approach to spatially and temporally confine immune activation to the tumor site, effectively broadening the therapeutic window and transforming RT-induced biochemical changes into a precise trigger for systemic immunity.

Renewable-electricity-driven CO₂-to-CO electroreduction is a promising approach for sustainable carbon utilization, yet efficient CO production requires precise control of interfacial adsorption, proton-coupled electron transfer, and competing hydrogen evolution. Isolated metal centers are often constrained by linear scaling relationships, hindering the simultaneous optimization of CO₂ activation, *COOH formation, and suppression of the hydrogen evolution reaction. Herein, we report an N-doped carbon catalyst derived from zeolitic imidazolate framework-8, containing neighboring Cu/Ni sites that cooperatively regulate the CO₂-to-CO pathway. Aberration-corrected high-angle annular dark-field scanning transmission electron microscopy reveals atomically dispersed metal features and neighboring bright-spot configurations with a projected-separation distribution centered at approximately 2.35 Å, while localized electron energy-loss spectroscopy supports Cu/Ni coexistence within representative neighboring regions. The optimized catalyst achieves a CO Faradaic efficiency of approximately 99% at −0.70 V versus the reversible hydrogen electrode, with a corresponding CO partial current density of 31.78 mA cm⁻², and maintains stable operation for 52.3 h. Post-reaction scanning transmission electron microscopy and X-ray photoelectron spectroscopy further indicate that the atomically dispersed metal features and metal–N coordination environments are largely preserved after long-term electrolysis. Density functional theory calculations based on a representative adjacent Cu/Ni–Nₓ model show that the free-energy change for the potential-determining *COOH formation at the Ni-centered site is 1.08 eV. Electronic-structure analyses further suggest that neighboring Cu modulates the local electronic environment of Ni, contributing to site-differentiated interfacial reactivity. This work establishes a link between neighboring Cu/Ni sites, interfacial electronic modulation, and CO₂-to-CO performance, providing an interface-engineering strategy for selective CO₂ electroreduction.

Pork is highly perishable during storage, leading to enormous economic losses and potential food safety hazards. Anthocyanins (ANTs) possess excellent antioxidant and antibacterial activities, but their poor stability in practical applications limits their industrial application. To address these issues, a novel composite preservation film was prepared by the four-sided applicator solution casting method, using polylactic acid (PLA) and polybutylene adipate-co-terephthalate (PBAT) as matrix materials and ANTs@ZIF-8 as functional filler. Zeolitic imidazolate framework-8 (ZIF-8) encapsulated ANTs to enhance its stability and achieve sustained release, while the PLA/PBAT was selected for its good biodegradability, mechanical and barrier properties. The structure and properties of the PLA/PBAT/ANTs@ZIF-8 composite films were investigated, and the results showed that ANTs@ZIF-8 nanoparticles had stable dispersibility in the matrix, which effectively improved the compatibility between nanoparticles and the film matrix. The prepared composite films exhibited excellent tensile strength (TS), elongation at break (EAB) and water vapor transmission rate (WVTR), as well as good antibacterial activity againstE. coliandS. aureus. Furthermore, the practical pork preservation performance of the films was investigated, and the results demonstrated that the composite films could effectively reduce the pH value, water loss, color difference, total volatile basic nitrogen (TVB-N) content and malondialdehyde (MDA) content of fresh pork during storage, successfully extending the shelf life of pork to 12 days. This study develops a multifunctional, biosafe, and biodegradable PLA/PBAT composite film incorporated with ANTs@ZIF-8, providing a feasible strategy and scientific reference for the design and development of high-performance active biodegradable packaging materials.

Thermally activated ZIF-8 exhibits a narrowed bandgap of 2.19 eV. • PS@ZIF-8-T NFM achieves 98.1% PM 2.5 filtration with low pressure drop. • 90.4% formaldehyde degraded within 1 h under visible light. • 81.25% E. coli inactivation achieved after 30 min illumination. • Superhydrophobic surface (WCA 150.6°) ensures self-cleaning ability. Nanofiber membranes offer significant potential for air purification; however, conventional membranes are typically limited to particle filtration and lack functionality against bacteria or volatile organic compounds. To address this, this study fabricated a multifunctional photocatalytic nanofibrous membrane by electrospinning polystyrene (PS) with ZIF-8-T (the air-thermally treated ZIF-8) as a photocatalyst. ZIF-8-T has a specific functional group, isocyanate (-N=C=O), with a band gap of 2.19 eV and exhibits broad-spectrum photo-response properties (200–800 nm). The optimized membrane with a 150 wt% ZIF-8-T loading demonstrated excellent integrated performance: a high PM 2.5 filtration efficiency of 98.1%, rapid degradation of 90.4% formaldehyde within 1 h under illumination, and superhydrophobicity with a water contact angle of 150.6°. Moreover, it achieved an antibacterial rate of 81.25% against E. coli within 30 mins of light exposure. This work presents a viable strategy for designing MOF-based composite membranes that integrate efficient filtration, photocatalytic degradation, and antibacterial functions for advanced air purification.

Lavender essential oil (LEO) has strong antibacterial and antioxidant properties, but its volatility limits practical use in fruit preservation. To address this limitation, we developed a pH-responsive delivery system (LEO@HZIF-8) using tannic acid (TA)-etched hollow ZIF-8 (HZIF-8) to enable controlled release of LEO. Mild etching generated a hollow structure that increased LEO encapsulation efficiency to 68.96%. Results indicate that LEO@HZIF-8 nanoparticles retain a well-defined crystalline structure and release LEO rapidly under acidic conditions, with a release rate of 73.36% at pH 4.5 after 72 h. Furthermore, LEO@HZIF-8 exhibited strong antioxidant activity, with DPPH and ABTS radical-scavenging rates of 85.48% and 78.24%, respectively, and significant antibacterial activity. When incorporated into a sodium alginate/zein (SA/Zein) coating, LEO@HZIF-8 extended the shelf life of white apricots to 63 days and effectively delayed decay, weight loss, and firmness loss. This study demonstrates an efficient pH-responsive delivery strategy for plant essential oils in freshness preservation and provides a basis for developing next-generation smart, eco-friendly active food packaging materials.

This study reports the one-step in-situ assembly of a polydopamine (PDA)@ZIF-8 functional layer on polyethersulfone (PES) ultrafiltration (UF) membranes for high-flux, antifouling dye/salt separation. Leveraging the synergistic effect of dopamine (DA) self-polymerization and the in-situ growth of ZIF-8 during the nonsolvent-induced phase separation (NIPS) process, a highly integrated PDA@ZIF-8 functional layer was successfully constructed on the PES membrane surface. Strong coordination and chelation interactions among Zn 2 + ions, the catechol moieties of PDA, and 2-methylimidazole (2-MIM) increase the casting solution viscosity, triggering delayed demixing and promoting the migration of hydrophilic precursors toward the membrane interface. Structurally, the in-situ assembly of PDA@ZIF-8 significantly increased the selective layer thickness from 4.73 μm to 33.10 μm. The resulting ultrafiltration membrane exhibited exceptional separation efficiency, delivering a Congo Red (CR) rejection rate of over 99.5% while maintaining a salt rejection rate under 5%, enabling the efficient fractionation of dyes and salts. A high pure water flux of 455 L·m −2 ·h −1 at 0.1 MPa is attained, which is attributed to the enhanced surface hydrophilicity and the intrinsic sub-nanometer microporous channels of ZIF-8. Furthermore, the functionalized layer demonstrates remarkable antifouling properties toward anionic dyes, with a stable flux recovery ratio (FRR) exceeding 85% after multiple cycles of CR filtration. This research presents an effective membrane preparation strategy that enhances separation performance while ensuring excellent long-term antifouling stability.
