ZZP-TENGs are designed for monitoring the HCHO concentration with high-pressure gas streams. • ZZP-TENG exhibited excellent sensing performance of HCHO. • ZZP-TENGs can be employed to construct an HCHO early warning system. • ZZP-TENG is applicable for detecting changes in indoor HCHO concentration. Formaldehyde (HCHO), a hazardous volatile organic compound, poses serious threats to human health in daily life and industrial environments. Herein, a pulse airflow-driven triboelectric nanogenerator (ZZP-TENG) with a ZIF-8/ZIF-67/copper foam composite microstructure was fabricated for high-sensitivity HCHO detection. Benefiting from micro/nano structural modification, the ZZP-TENG efficiently harvested ambient mechanical energy, yielding a short-circuit current of 3.62 μA and a maximum output power of 45.63 μW. Its stable energy output could drive 54 LEDs and charge various capacitors, demonstrating reliable energy-harvesting capacity. The sensor exhibited an 80% response toward HCHO at 40 ppm, along with a 30 s response time and an 80 s recovery time at 20 ppm. To verify practical indoor application feasibility, a simulated post-renovation HCHO release scenario was constructed with HCHO-containing wood blocks, supporting accurate indoor air quality assessment and environmental safety evaluation. In this study, an improved extreme learning machine (ELM) algorithm was employed to classify HCHO signals from the ZZP-TENG sensor. The ELM model realized 100% HCHO concentration recognition accuracy and constructed a three-level safety early warning system, achieving real-time intelligent indoor HCHO monitoring. This work realizes simultaneous airflow energy harvesting and HCHO detection, providing a novel route for integrated gas sensors and broadening the application of TENGs in self-powered indoor environmental monitoring. After the decoration of indoor residential and office spaces, formaldehyde (HCHO) is continuously released from building materials, furniture, and coatings, posing a serious threat to human health due to its chronic toxicity and carcinogenicity. When HCHO accumulates beyond the safe threshold, it causes eye irritation, respiratory inflammation, and long-term immune system disorders. In this study, a pulse airflow-driven triboelectric nanogenerator (ZZP-TENG) with a ZIF-8/ZIF-67/copper foam composite microstructure was fabricated for high-sensitivity HCHO detection. The self-powered device efficiently harvested ambient mechanical energy and delivered sufficient electrical output for continuous sensing. By integrating with a machine learning framework, the system achieved precise and graded evaluation of dynamic formaldehyde concentration throughout a six-week natural attenuation process. Furthermore, the integrated wireless alarm system enables real-time risk warning once pollutants exceed the safety threshold, realizing intelligent, long-term, and safe indoor air quality monitoring for residential and office environments.

The blue and deep-red wavelengths emitted by plant growth lamps effectively encompass the entire spectrum of plant pigments essential for optimal growth. Nevertheless, inadequate thermal stability and poor quantum efficiency impede advancements in plant lighting technology. In this study, Ce3+and Mn2+ions are co-doped into the BaCa13Mg2(SiO4)8matrix to develop a phosphor that encompasses the entire absorption wavelength range of plant pigments. Ce3+and Mn2+ions can emit blue light and red light in the range of 380–550 nm and 600–760 nm, respectively. As an excellent sensitizer, Ce3+ions can significantly enhance the luminescence efficiency of Mn2+ions, with a quantum efficiency of 51.03%. The analysis of crystal structure, spectroscopy, and energy transfer mechanisms clarifies the fundamental factors contributing to the observed high quantum efficiency. Theoretical calculations show that dipole–dipole interactions dominate the energy transfer process. At 140 °C, the emission intensity of the whole sample region can reach 92.83% of the integrated emission intensity. The electroluminescence spectrum of the sample overlaps substantially with the spectrum required for optimal absorption by the plant. The results show that BaCa13Mg2(SiO4)8: Ce3+, Mn2+phosphors have excellent properties and inspire broad application prospects in the plant lighting field.

LbL-confined in situ ZIF-8 growth enabled high-performance NF membranes. • ZIF-8 nanochannels improved ion sieving and transport regulation. • The membrane achieved 98.5% Na 2 SO 4 rejection with improved permeance. • The membrane achieved 93.8% flux recovery and excellent operational stability. In this study, a high-performance nanofiltration membrane was developed by integrating layer-by-layer (LbL) polyelectrolyte assembly with confined in situ growth of zeolitic imidazolate framework-8 (ZIF-8). A PEI/PSS multilayer was constructed on a polyethersulfone (PES) support through sequential electrostatic deposition, providing a nanoscale confined environment for regulating ZIF-8 nucleation and growth. Zn 2+ ions and 2-methylimidazole were subsequently introduced into the multilayer structure, enabling the formation of ZIF-8 nanocrystals within the polyelectrolyte matrix rather than conventional particle incorporation. The optimized membrane achieved a Na 2 SO 4 rejection of 98.5 ± 0.3% with a permeance of 7.1 ± 0.1 L m −2 h −1 bar −1 , representing a 65% enhancement compared with the PEI/PSS counterpart. Meanwhile, MgCl 2 rejection increased from 64.6% to 93.0%, indicating improved divalent ion selectivity. These improvements were attributed to the confined ZIF-8 nanostructures, which optimized the selective layer architecture, reduced non-selective defects, and regulated ion transport behavior. Furthermore, the membrane maintained high salt rejection (>93%) under Na 2 SO 4 concentrations of 1–5 g L −1 and exhibited excellent antifouling performance with a flux recovery ratio of 93.8 ± 0.8%. This work provides an aqueous-phase strategy for constructing MOF-polyelectrolyte hybrid selective layers with enhanced ion selectivity, antifouling capability, and operational stability for advanced water separation applications.

The photocatalytic conversion of CO 2 into solar fuels presents a sustainable approach to alleviate climate change and address energy crisis. To address the limitations of conventional photocatalysts, such as their restricted visible-light response and rapid charge recombination, we have developed a ternary nanocomposite consisting of zeolitic imidazolate framework-8 (ZIF-8), plasmonic gold nanoparticles (Au NPs), and titanium dioxide (TiO 2 ). In this system, ZIF-8 provides high-density CO 2 adsorption sites, enhancing the local concentration of CO 2 and facilitating its subsequent reduction. The incorporation of Au NPs induces a strong localized surface plasmon resonance (LSPR) effect, significantly broadening the visible-light harvesting capability of the composite and promoting efficient charge transfer between TiO 2 and ZIF-8. TiO 2 serves as a stable photocatalytic platform, enabling effective charge separation and transfer. Comprehensive characterization verifies the uniform integration of the three components and the formation of close interfacial contacts. The ternary nanocomposite demonstrates significantly improved visible-light absorption, reduced charge recombination, and enhanced photogenerated carrier separation and transfer, as supported by UV-vis diffuse reflectance spectroscopy (DRS), photoluminescence (PL), electrochemical impedance spectroscopy (EIS), and photocurrent measurements. Under simulated sunlight, the ZIF-8/Au/TiO 2 photocatalyst achieves CO 2 -to-fuel conversion rates of 1.56 μmol g −1 h −1 for methane (CH 4 ) and 4.65 μmol g −1 h −1 for carbon monoxide (CO). This enhancement is attributed to the synergistic effects of plasmonic sensitization by Au nanoparticles and CO 2 adsorption enrichment by ZIF-8, which collectively enhance photon utilization, reactant concentration, and interfacial charge transfer dynamics.

Human carboxylesterase 1 (hCE1) is a serine hydrolase that is distributed widely in the human liver, intestines, and various tumour tissues. It has now become a biomarker associated with diseases such as cancer. Consequently, the measurement of hCE1 levels in human serum is of significant importance for the diagnosis and assessment of these diseases. The present study involved the preparation of Ag/CQDs/ZIF-8 nanocomposites, which incorporated silver nanoparticles (Ag NPs) and carbon quantum dots (CQDs) into the ZIF-8 framework. The combination of this composite with an enzyme-linked immunosorbent assay (ELISA) and the utilisation of benzidine as the signal molecule resulted in the development of a fluorescence (FL)/surface-enhanced Raman scattering (SERS) dual-mode sensor, which was employed for the sensitive detection of hCE1 in serum. This dual-mode sensor combines the advantages of both FL and SERS technologies, demonstrating excellent selectivity and stability, and enhancing the accuracy and reliability of quantitative measurements. The limits of detection (LOD) for the FL mode and SERS mode were determined to be 0.1 and 0.072 ng·mL − 1 , respectively, with the recoveries ranging from 92.44% to 117.47%. The satisfactory outcomes obtained from testing on real sample confirm the sensor’s excellent suitability for use in complex biological matrices. Consequently, this dual-mode sensor shows considerable promise for the detection of biomolecules in clinical samples, thereby demonstrating significant potential for clinical applications.

To address the challenge of preventing peri-implantitis, the present study developed a pH-responsive drug delivery coating on titanium (Ti) implants for controlled aspirin release. A hierarchical metal-organic framework coating was constructed on alkali- and heat-treated titanium by sequentially synthesizing Zeolitic imidazolate framework-L (ZIF-L) and ZIF-8 (denoted AHTL8). Material characterization confirmed the successful fabrication of a hierarchical micro–nano structure, which significantly enhanced surface hydrophilicity. The AHTL8 system exhibited a remarkably high aspirin-loading capacity (0.227 mg) and intelligent release kinetics, with sustained delivery (77.36% over 72 h) at physiological pH (7.4) and rapid, extensive release (97.39% over 72 h) under acidic conditions pH (6.5). Furthermore, the coating demonstrated excellent cytocompatibility, and the aspirin-loaded AHTL8 significantly promoted the proliferation of mouse osteoblastic MC3T3-E1 cells. These findings indicate that the ZIF-L/ZIF-8 composite coating serves as a highly efficient pH-triggered platform with high drug-loading and responsive release capacity, and its excellent cytocompatibility and MC3T3-E1 proliferation-promoting effect provide a preliminary basis for its potential application in promoting osseointegration.

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.

Porous carbon has emerged as a promising material for CO 2 capture owing to its low cost, high specific surface area, and tunable porosity, with surface chemistry and pore architecture serving as critical determinants of adsorption performance. To prevent specific surface area loss in heteroatom-doped biochar—a common limitation, bacterial cellulose (BC) was employed as a structural template to facilitate the in-situ growth of nitrogen-rich ZIF-8 crystals along its fibrous network, forming hybrid composites. Subsequent carbonization yielded N-doped biochar featuring a highly porous, three-dimensionally interconnected architecture. BC contains a large number of oxygen-containing groups. This can facilitate the uniform growth of ZIF-8 along nanofibers. During the high-temperature carbonization process, ZIF-8 creates a large number of micropores through gasification etching and is simultaneously transformed into high-concentration nitrogen-doped porous carbon nanofibers. The 900 °C carbonized sample (CBCZ-900) combines high specific surface area and outstanding CO 2 adsorption (5.35 mmol/g) with exceptional cycling stability, positioning it as a viable candidate for industrial carbon capture systems.

Given the vital nutritional and metabolic role of ascorbic acid (AA) and the need for rapid detection, a photoresponsive nanozyme-based composite was developed for sensitive, accurate, and convenient AA analysis. In this report, a ternary ZIF-8/g-C 3 N 4 /SiO 2 photoresponsive oxidase-mimicking system was developed and applied to AA detection. By regulating the loading ratio of ZIF-8 on the g-C 3 N 4 /SiO 2 substrate, the composite with excellent photoresponsive oxidase-like activity was successfully prepared. Owing to its enhanced visible-light absorption and efficient charge separation and transfer, the system exhibited significantly improved photoresponsive performance. Experimental results demonstrated that ZIF-8/g-C 3 N 4 /SiO 2 could catalyze the oxidation of 3,3′,5,5′-tetramethylbenzidine (TMB), generating oxidized TMB (oxTMB) through the formation of reactive species, thereby producing a distinct color change. In an acidic environment, AA inhibited the oxidase-like activity of the catalyst due to its strong reducing capability, thus suppressing the colorimetric reaction. Based on this principle, the as-synthesized ZIF-8/g-C 3 N 4 /SiO 2 photoresponsive oxidase mimic was applied to the detection of AA in three beverages. The method revealed a good linear response within the concentration range of 1–40 μM, and the detection limit (LOD) was 0.14 μM. The recoveries of the spiked samples ranged from 95.00% to 103.85%, suggesting that the present method could be successfully applied to sense AA in practical samples. Furthermore, we integrated ZIF-8/g-C 3 N 4 /SiO 2 with the RGB strategy into a novel sensing platform for the visual/onsite semi-quantitative detection of AA in real samples, demonstrating the great potential prospects for the development of rapid food assay.

A novel ZIF-8@Nar@CS nanocomposite was synthesized by a ternary co-assembly strategy. • ZIF-8@Nar@CS has pH-responsive drug release feature following first-order kinetics. • ZIF-8@Nar@CS revealed strong bactericidal effect against E. coli and S. aureus . • ZIF-8@Nar@CS enhanced cytocompatibility and osteogenic activity as compared to ZIF-8. • The designed drug-delivery platform shows potential to be used in orthopedics field. Development of functional nanocomposites for bone tissue repair is often hampered by their bioinertness and insufficient antibacterial performance. To overcome the limitation, this study developed a novel ZIF-8@Nar@CS composite nanoparticle system via a ternary co-assembly strategy. The microstructure of the ZIF-8@Nar@CS was explored by SEM, XRD, FTIR, UV–Vis, BET, and the interaction mechanism of the composite was elucidated via XPS and zeta potential analysis. In addition, the drug release behavior, antibacterial activity and osteogenic property of the composite were also evaluated in vitro. The results show that the ZIF-8@Nar@CS achieved a naringin (Nar) drug loading efficiency of 19.22% through the electrostatic interactions and exhibited a distinct pH-dependent drug release profile. Its cumulative release reached 98.89% at pH 5.5, in stark contrast to only 13.6% at pH 7.4, following first-order kinetics. Profiting from the concomitant release of Zn 2+ , Nar, and chitosan (CS), the ZIF-8@Nar@CS exerted a strong antibacterial activity of 99.99% against both S. aureus and E. coli . Critically, the ZIF-8@Nar@CS also exhibited favorable cytocompatibility and effectively enhanced the osteo-differentiation of MC3T3-E1 cells as compared to the ZIF-8 nanocarrier. This work might provide a new horizon for developing a safe nanoparticle delivery platform for bone repair and regeneration in clinic.

As a highly valued natural lignocellulosic biopolymer, bamboo plays a critical role in developing sustainable material systems. However, when exposed to rainwater, this biopolymeric substrate is highly susceptible to fungal degradation, making it difficult for traditional fungicides to retain long-term efficacy. Their inevitable leaching weakens antifungal performance and raises environmental concerns, while conventional treatments often compromise the mechanical integrity of the lignocellulosic structure. Therefore, developing green, durable, and substrate-compatible antifungal technologies is essential. Nanoscale zinc oxide (ZnO) is a promising inorganic antimicrobial agent due to its multi-mechanism activity and favorable biosafety, yet issues like agglomeration, poor stability, and rapid ion release limit its long-term performance. To overcome these drawbacks, a stepwise in-situ construction strategy is introduced, where a ZnO layer is first grown as both the core and zinc source to direct ZIF-8 formation, yielding a shell that stabilizes ZnO and ensures sustained Zn 2+ release for long-lasting antifungal efficacy. Comprehensive characterization verifies the successful formation of a compact, crystalline core-shell heterostructure well-integrated with the biopolymer matrix. Mechanical testing confirms that the ZnO@ZIF-8 treatment preserves the intrinsic mechanical properties of the bamboo, maintaining a tensile strength of 96.52 MPa while elevating bending strength by 31.79% to 169.46 MPa. Anti-mold and anti-leaching evaluations further demonstrate excellent durability, maintaining Grade 0 (no mold growth) infection after 14 days of leaching and 28 days of humid-heat incubation. This work presents an efficient, durable, and environmentally friendly antifungal strategy for bamboo, offering valuable insights into the application of metal oxide-MOF composites in bamboo protection.

Accurate detection of carbon dioxide (CO₂) is important in environmental monitoring and industrial process control. Optical fiber sensors have attracted considerable attention for CO₂ detection owing to their compact size, immunity to electromagnetic interference, and capability for remote sensing. However, achieving high sensitivity and adsorption affinity within practical CO₂ concentration ranges remains challenging. In this work, we propose a fiber interferometric CO₂ sensor based on a cascaded dual-sphere intermodal interferometer (IMI) functionalized with a ZIF-8/graphene oxide (GO) hybrid membrane. The dual-sphere interferometric structure enhances the interaction between cladding modes and the surrounding environment, while the ZIF-8/GO hybrid membrane provides a hierarchical adsorption–diffusion interface that improves CO₂ adsorption affinity and gas transport efficiency. Experimental results show that the sensor exhibits a high sensitivity of −286 pm/% CO₂ within the concentration range of 0.5–4.0%, together with excellent linearity (R² = 0.998), good repeatability, and negligible interference from temperature and humidity variations. Furthermore, the hierarchical micro-mesoporous architecture facilitates efficient gas diffusion, endowing the sensor with favorable response and recovery kinetics for continuous monitoring applications. These results indicate that the proposed sensing strategy provides an effective approach for high-performance optical fiber CO₂ sensing through the integration of an optimized interferometric structure and a hybrid MOF/2D sensing membrane.
