The integration of pressure-sensing materials into wearable protection systems has great potential for intelligent safety monitoring. While modern cycling helmets are effective at dissipating impact energy, they still lack real-time sensing and localization capabilities, hindering timely injury assessment. In this study, a humidity-induced phase separation electrospinning strategy (HIPS) is developed to produce an ultralight three-dimensional sponge-structured triboelectric sensor (3D-STS), in which polyacrylonitrile (PAN)/zinc-based metal-organic framework (Zn-MOF) composite is used as the core sensing material. Owing to its hierarchical 3D structure and well-dispersed Zn-MOFs, the 3D-STS exhibits improved mechanoelectric conversion performance, achieving a sensitivity up to 3.83 V/kPa in the low-pressure range 0.02–0.7 kPa. Furthermore, the as-prepared 3D-STS withstands impacts at up to 2 m/s while maintaining over 96% of its electrical output after 10,000 compression cycles, indicating its excellent mechanical durability. When sixteen 3D-STS units were integrated into a helmet to form a 16-channel sensing system, the system enabled real-time multisite impact monitoring through a LabVIEW interface and achieved over 95% accuracy in tests. This research overcomes the limitations of conventional helmet sensors in real-time pressure detection and opens new possibilities for smart, self-responsive protection systems.

A portable, high-throughput visual sensing platform was constructed for the effective detection of catechol (CA), on the basis of the single-electrode electrochemistry system (SEES) and a self-enhanced electrochemiluminescence (SEECL) material, namely Au-Ru@Zn metal-organic framework (MOF). It was found that Ru(bpy) 3 2+ and oxalate co‑encapsulated within the Ru@Zn MOF generated a SEECL signal. To further amplify the SEECL response, tripropylamine (TPA) was introduced as an exogenous co-reactant, synergizing with endogenous oxalate to establish dual ECL pathways. The oxidation product of CA, semiquinone radicals, is proposed to effectively quenched photoexcited Ru(bpy) 3 2+ * species and competitively consume the precursor Ru(bpy) 3 3+ by reducing it to Ru(bpy) 3 2+ , thereby causing the ECL signals of Au-Ru@Zn MOF to be significantly quenched. Under optimal experimental conditions, the Au-Ru@Zn MOF-modified SEES exhibited excellent ECL response performance toward CA, with a linear detection range from 1.0 × 10⁻ 9 to 5.0 × 10⁻ 4 mol·L⁻ 1 and a detection limit as low as 7.94 × 10⁻ 10 mol·L⁻ 1 (S/ N = 3). Additionally, the proposed SEES successfully detected CA in tea with the recoveries ranging from 98.8% to 101.0%. This work offers a novel approach for the sensitive detection of CA and has significant application possibilities in the realm of food safety monitoring with the benefits of high throughput, portability, and low cost.

With the increasing concern over food safety, the development of smart labels capable of visually monitoring food freshness in real-time has become increasingly urgent. In this study, a novel zinc-based metal-organic framework (Zn-MOF) was synthesized and incorporated into a poly(vinyl alcohol) and starch matrix to prepare PS@Zn-MOF composite films. The films demonstrated colorimetric and fluorescent dual-signal responsiveness, ammonia sensitivity, and antimicrobial properties. A comprehensive evaluation of the films revealed excellent mechanical properties, UV shielding ability, and water vapor barrier capabilities. Furthermore, the films exhibited color stability, with a ΔE value change of <2.4 after 40 days of exposure. When applied to monitor shrimp spoilage, the films shifted from yellow-brown to purple-red in daylight and from blue to violet fluorescence under UV light. The color difference and fluorescence intensity in both response modes were linearly correlated with TVB-N values. The shrimp packaging application demonstrated that the films effectively maintained shrimp freshness. These findings suggest that the dual-signal intelligent freshness monitoring system based on PS@Zn-MOF composite films presents a promising solution to food safety challenges.

Photochromic hydrogels, which are dynamic in response to external light stimuli, have aroused increasing attentions due to their potential applications in intelligent devices. However, achieving excellent photochromic activity with fast photoresponse and self-bleaching rates still remains a huge challenge. Herein, a novel photochromic junction of zinc-based metal–organic framework (Zn-MOF) and tungsten oxide (WO 3 ) was established as photochromic unit and embraced within hydrogel of poly(acrylic acid- co -polyethylene glycol) [P(AA/PEG)] via the interaction of ionic and hydrogen bonding (denoted as P(AA/PEG)-Zn-MOF@WO 3 ), following by exploiting as self-bleaching photochromic agent for assembling UV-irradiated smart rewritable device. The photoinduced electrons can be efficiently separated and migrated from Zn-MOF to WO 3 in the Zn-MOF@WO 3 junction after UV irradiation, thereby increasing the coloration degree. Due to the enhanced fast response to light stimuli, the P(AA/PEG)-Zn-MOF@WO 3 -3 hydrogel prepared using 200 mg Zn-MOF demonstrated the fast responsive photochromic behavior of 10 s under UV lamp illumination and the self-fading process could be easily performed in room condition (within 20 min). Moreover, the coloration degree of P(AA/PEG)-Zn-MOF@WO 3 -3 photochromic hydrogel was precisely controlled and repeated by changing the UV irradiation time. Consequently, the fast photochromic and self-fading properties of P(AA/PEG)-Zn-MOF@WO 3 -3 afforded rapid and easy ‘‘writing’’ and “erasing” abilities. The present work proposes a new way for the construction of the reversibly responsive photochromic hydrogel with smart optical materials, further broadening their applications in intelligence sensors, smart windows, and flexible memory devices.

4-Chloroaniline (4-CAN) plays an important role in chemical and industrial production. However, it remains a challenge to avoid the hydrogenation of the C–Cl bond in the synthesis process to improve selectivity under high activity conditions. In this study, we in situ fabricated ruthenium nanoparticles (Ru NPs) containing vacancies inserted into porous carbon (Ru@C-2) as a highly efficient catalyst for the catalytic hydrogenation of 4-chloronitrobenzene (4-CNB) with remarkable conversion (99.9%), selectivity (99.9%), and stability. Experiments and theoretical calculations indicate that the appropriate Ru vacancies affect the charge distribution of the Ru@C-2 catalyst, promote the electron transfer between the Ru metal and support, and increase the active sites of the Ru metal, thus facilitating the adsorption of 4-CNB and the desorption of 4-CAN to improve the activity and stability of the catalyst. This study can provide some enlightenment for the development of new 4-CNB hydrogenation catalysts.

Enhancing performance through the combination of polyoxometalates (POMs) clusters with metal–organic frameworks (MOFs) that contain various transition metals is a challenging task. In this study, we synthesized a polyoxometalate-based metal–organic framework (POMOF) named HRBNU-5 using a solvothermal method. HRBNU-5 is composed of Zn[N(C 4 H 9 ) 4 ][MnMo 6 O 18 {(OCH 2 ) 3 CNH 2 } 2 ]@Zn 3 (C 9 H 3 O 6 ) 2 ·6C 3 H 7 NO, which includes two components: Zn[N(C 4 H 9 ) 4 ][MnMo 6 O 18 {(OCH 2 ) 3 CNH 2 } 2 ]·3C 3 H 7 NO ({Zn[MnMo 6 ]}) and Zn 3 (C 9 H 3 O 6 ) 2 ·3C 3 H 7 NO (Zn-BTC). Structural characterization confirmed the host–guest structure, with Zn-BTC encapsulating {Zn[MnMo 6 ]}. In a three-electrode system, HRBNU-5 exhibited a specific capacitance of 851.3 F g −1 at a current density of 1 A/g and retained high stability (97.2 %) after 5000 cycles. Additionally, HRBNU-5 performed well in aqueous-symmetric/asymmetric supercapacitors (SSC/ASC) in terms of energy density and power density in a double-electrode system. Moreover, it demonstrated excellent catalytic performance in a 1.0 M KOH solution, with low overpotentials and Tafel slopes for hydrogen and oxygen evolution reactions: 177.1 mV (η 10 HER), 126.9 mV dec –1 and 370.3 mV (η 50 OER), 36.3 mV dec –1 , respectively, surpassing its precursors and most reported studies. HRBNU-5′s positive performance is attributed to its host–guest structure, high electron-transfer conductivity, and porous structure that enhances efficient mass transport. This work inspires the design of Anderson-type POMOF electrode materials with multiple active sites and a well-defined structure.

Introduction Sulfamethazine (SM2) antibiotic residues in food pose a significant risk to human health, including pathogenic bacterial resistance, allergic reactions, and carcinogenicity. Current lateral flow immunoassay (LFIA) typically employing colloidal gold (AuNP) as a signal reporter exhibits unsatisfactory sensitivity. Recently, metal–organic frameworks (MOFs) nanomaterial as a supporting matrix for loading nanoparticles provides a powerful tool to improve the performance of LFIA. Objectives This study aims to develop an enhanced immunosensor based on antibody labeled Au/Ir@Cu/Zn-MOF signal amplification nano-composite for sensitive and point-of-care monitoring of SM2 antibiotic residues. Methods Firstly, the highly specific monoclonal antibody (mAb) against SM2 belonging to the IgG1 subclass was screened. Subsequently, the Au/Ir@Cu/Zn-MOF nanocomposite was synthesized by incorporating Au/Ir bimetallic nanoparticles into the previously prepared Cu/Zn-MOF composite. The anti-SM2 mAb was then conjugated to Au/Ir@Cu/Zn-MOF nanocomposite via a co-precipitation method to fabricate the mAb-Au/Ir@Cu/Zn-MOF probe. Finally, a lateral flow immunoassay was constructed for the detection of SM2 residues. Results The vLOD the Au/Ir@Cu/Zn-MOF-based LFIA for SM2 detection was approximately 2.5 ng/mL, which was at least 600 times greater than that of the AuNP-based LFIA (with the vLOD of 1563 ng/mL). Average recovery rates were 80.08–90.8% in milk sample, 88–89.3% in eel sample and 85.3–95.2% in pork sample, respectively. Conclusion The Au/Ir@Cu/Zn-MOF nanocomposite utilized as signal amplification probe demonstrated remarkable sensitivity for the detection of SM2. The developed Au/Ir@Cu/Zn-MOF-based LFIA exhibits significant potential for the rapid and sensitive detection of contaminants in environmental monitoring and food safety.

Accurate monitoring of copper ions (Cu 2+ ) and lipoic acid (LA), essential trace elements and antioxidants in vegetables, is critical for food safety and human health. Here, we developed mercaptopurine-stabilized gold-silver bimetallic nanoclusters (MP-AuAg NCs) as a fluorescence 'turn-off' probe for Cu 2+ detection, achieving a linear response of 0.05–20 μM with a detection limit of 23 nM (LOD). To enhance sensitivity, a ratiometric probe (Zn MOF@MP-AuAg NCs) was engineered by in situ growth of zinc metal organic frameworks (Zn MOF) in the nanoclusters, which reduced Cu 2+ LOD to 4 nM (linear range: 0.015–0.50 μM). Interestingly, the Cu 2+ quenched system functioned as a 'turn on' sensor for LA detection, offering a dual range response: exponential correlation from 0.3 to 80 μM (R 2 = 0.997) and linear quantification from 0.3 to 25 μM (LOD = 94 nM, R 2 = 0.998). Validated in spinach samples, the method demonstrated exceptional precision (recoveries: 96.5–102 %) and precision (RSD <3.12 %), confirming its reliability for sequential Cu 2+ -LA analysis in complex food matrices. This work establishes a versatile sensing platform with enhanced sensitivity and practical utility for food quality monitoring.

Aluminum alloys are widely used in marine engineering due to their excellent strength-to-weight ratio. However, these materials are susceptible to localized corrosion phenomena, especially pitting and intergranular corrosion in corrosive marine environments, which greatly reduces their durability. To address this challenge, we have developed an innovative GO/MXene@ZIF-8-BTA nanocomposite epoxy coating system that strategically integrates multilayered GO/MXene heterostructures with ZIF-8 nanoparticles encapsulated with benzotriazole (BTA). Comprehensive characterization of physicochemical properties, colloidal stability, surface wettability, and corrosion protection properties confirmed the homogeneous dispersion and excellent compatibility of the nanocomposites. Electrochemical impedance spectroscopy (EIS) showed a low-frequency impedance modulus of 1.08 × 10 8 Ω•cm 2 , which is two orders of magnitude higher than that of the pristine epoxy resin after 21 days of immersion in a 3.5 wt% NaCl solution. The autonomous self-healing function was verified by a scratch test, where the corrosion rate was suppressed to 0.152 mpy in 48 hours (protection efficiency of 84.41%). Complementary density-functional theory (DFT) simulations provide atomic-scale insight into the energetics of adsorption, suggesting a pioneering approach to the long-term protection of aluminum alloys under extreme ocean service conditions.

Background Epithelial cell adhesion molecules (EpCAM) protein is one of the most frequently and intensely studied tumor-associated antigens because of its overexpression in most cancer cells. Thus, it is regarded as a tumor biomarker associated with a wide variety of carcinomas and reflects the existence and growth of tumors in the human body. It is highly required to detect low concentrations of EpCAM in early stage for ensuring human health. Results In this study, a novel sandwich electrochemiluminescence (ECL) aptasensor was developed for EpCAM detection. Wherein oxalate-based Zn-MOF supported tris(2,2′-bipyridyl)ruthenium (II) (Ru(bpy) 3 2+ @Zn-MOF) was used as luminophore and gold nanoparticle modified o-phenylenediamine (PoPD@Au NPs) as quencher. The 3D Ru(bpy) 3 2+ @Zn-MOF generated self-enhanced ECL without additional co-reactants. Furthermore, it remained stable and had short electron transfer distance, ensuring high and stable ECL signal. The ECL signal could be effectively quenched by PoPD@Au NPs through resonance energy transfer (RET) and electron transfer (ET), due to its absorption spectrum overlapping with the ECL emission spectrum of Ru(bpy) 3 2+ @Zn-MOF. In the presence of EpCAM, the aptamer acted as a linker between the luminophore and quencher, forming a sandwich structure that had reduced ECL intensity. Under optimal conditions, EpCAM could be sensitively detected over the range of 1 pg mL -1 -100 ng mL -1 , with a detection limit of 0.34 pg mL -1 . Significance This work developed a ECL aptasensor with self-enhanced Ru(bpy) 3 2+ @Zn-MOF luminophore for EpCAM detection. The ECL system was simple, but ultrasensitive for EpCAM monitoring, thanks to the ECL-RET and ET between Ru(bpy) 3 2+ @Zn-MOF and PoPD@Au NPs. It also could be applied to detect other biomolecules by replacing the aptamer, offering significant potential in disease diagnosis.

Because of the detrimental effects of excessive exposure to solar ultraviolet radiation (UVR) on human skin health, wearable UVR detectors have attracted more and more attention. Inspired by the artwork “Tian-tsui hair pin with flora decoration” from the Palace Museum, a reversible and photochromic peony-shaped hairpin is designed to realize the visualized detection of solar UV radiation. It is prepared via electrospinning a mixed solution containing thermoplastic polyurethanes (TPUs) and Zn-MOF@WO3 onto microfiber nonwoven fabrics (MFNFs). Because of the enhanced UV responsive and photochromic capability from Zn-MOF@WO3 as well the excellent flexibility from TPUs and MFNFs, the obtained hairpin presents an excellent photoresponsive and wearable performance. When exposed to UV radiation from sunshine, the hairpin switches from white to light blue and finally to blue with radiation time. The colors light blue and blue can be used to indicate the UV radiation doses for the synthesis of vitamin D and the induction of erythema, respectively. With the assistance of oxygen in air, the hairpin recovers to its original state after being maintained in a dark atmosphere for 12 h. Even after six cycles of exposure to UV radiation and recovery in the dark, the photochromic performance almost remains unchanged. Only a minor reduction of 5% is observed. As a traditional wearable headdress in China, the peony-shaped hairpin prepared from the hybrid nanofibers not only presents oriental elegance but also is suitable for cyclical use in the daytime to monitor UV radiation for skin health management.
