HRP was covalently immobilized on MAF to form a biocomposite with high activity and fluorescence. • HRP@MAF exhibited a remarkable fluorescence quantum yield of 97.77%. • HRP@MAF showed superior substrate affinity with a Km value 25-fold lower than HRP. • A dual-mode colorimetric/ratiometric fluorescent sensor was developed for histamine. Integrating strong fluorescence and efficient biocatalysis within a single metal-organic framework (MOF) is attractive for advanced optical sensing. Herein, a highly emissive metal-organic framework (denoted as MAF) was constructed using ligands with aggregation-induced emission (AIE) properties, followed by horseradish peroxidase (HRP) immobilization to yield HRP@MAF with high catalytic activity and strong fluorescence. The resulting HRP@MAF exhibited a fluorescence quantum yield of 97.77%. Benefiting from the high surface area and porous structure of MAF, HRP@MAF showed markedly improved stability and substrate affinity toward 3,3′,5,5′-tetramethylbenzidine (TMB), with a K m value 25-fold lower than that of free HRP. Based on its catalytic and optical properties, a colorimetric/ratiometric fluorescence sensor was developed for histamine detection with detection limits of 1.71 μM and 0.56 μM, respectively. In addition, smartphone-integrated on-site detection was achieved with linear ranges of 10–1000 μM for the colorimetric mode and 1–1000 μM for the ratiometric fluorescence mode. This work establishes an effective strategy for constructing multifunctional sensing platforms by coupling AIEgens derived highly emissive MOFs with immobilized enzymes.

Carbon aerogels are highly promising lightweight microwave absorbers, yet their intrinsic brittleness and disordered pore structures significantly limit both mechanical reliability and electromagnetic (EM) performance. Here, a flexible honeycomb-like anisotropic hybrid carbon aerogel (CFMT), modified with MoS 2 /FeS 2 nanoparticles and toughened by a polyurethane network, is developed to overcome these limitations. Benefiting from the aligned quasi-periodic pore architecture, CFMT exhibits a distinct anisotropic electromagnetic response. When incident waves propagate parallel to the honeycomb channels, strong dielectric relaxation is induced, and localized electromagnetic resonance (LEMR) is generated within the pore structure, enabling efficient capture and dissipation of centimeter-wavelength electromagnetic energy. Consequently, the CFMT aerogel delivers an ultrawide effective absorption bandwidth of 11.84 GHz, accompanied by a minimum reflection loss of −50 dB. In addition to excellent microwave absorption, the aerogel also demonstrates robust mechanical flexibility and superior infrared stealth capability. This work explicitly elucidates the mechanism by which quasi-periodic porous structures enhance microwave absorption performance, providing a highly effective design paradigm for next-generation, multifunctional, and flexible electromagnetic wave absorbers.

In this study, composite nanofibrous membranes composed of poly(vinyl alcohol) (PVA), gelatin, and zein loaded with different contents of dihydromyricetin (DMY) were fabricated via electroblowing spinning (EBS). The effects of DMY content on the microstructure, physicochemical properties, mechanical strength, and functional performance of the membranes were evaluated. Scanning electron microscopy (SEM) analysis showed that the average fiber diameter increased from 174 ± 29 nm to 221 ± 35 nm with increasing DMY content, followed by a slight decrease at higher loading levels, indicating that DMY incorporation influences fiber morphology. Fourier transform infrared spectroscopy (FTIR) results suggested the presence of hydrogen bonding interactions between DMY and the polymer matrix. X-ray diffraction (XRD) and differential scanning calorimetry (DSC) results indicated changes in the physical state of DMY within the nanofibrous system as the loading content increased. All samples exhibited a typical two-stage release behavior, and the highest cumulative release (nearly 55%) was observed at a DMY loading of 22.5%, while further increasing the loading reduced the release efficiency to approximately 45%. The release profiles were well described by a first-order kinetic model. The composite membranes exhibited improved surface hydrophilicity, appropriate water vapor permeability, antioxidant activity, and antibacterial activity againstEscherichia coli(E. coli) andStaphylococcus aureus(S. aureus). This study demonstrates the successful fabrication of DMY-loaded PVA/gelatin/zein nanofibrous membranes and provides preliminary insights into their structure–property–function relationships, release behavior, antioxidant activity, and antibacterial activity against representative bacteria, although further application-oriented validation is still required.

Surface contamination on photovoltaic glass severely degrades its power-generation efficiency, thereby making the development of transparent anti-soiling coatings an important research direction. Herein, a poly (methylmethacrylate)/1H,1H,2H,2H-perfluorooctyltriethoxysilane/SiO 2 (PMMA/PFOTS/SiO 2 ) organic–inorganic hybrid transparent superhydrophobic anti-fouling coating is developed via a one-step sol–gel method. The coating exhibits a stable Cassie-Baxter state with high water contact angle (155.2° ± 1.1°) and a low sliding angle (4.8° ± 0.7°), demonstrating excellent superhydrophobic characteristics. Optical tests demonstrate an average transmittance of 87.6% in the 400–2500 nm range and only 8.3% external quantum efficiency (EQE) attenuation at 800 nm compared to photovoltaic devices, significantly outperforming commercial superhydrophobic coatings (58.3% attenuation). This enables synergistic gains in dust resistance and photon capture efficiency. Additionally, after 24 h immersion in alkaline solution, the coating hydrophobicity is enhanced, with WCA increasing to 165.1° ± 1.4°. We believe that the designed superhydrophobic coating with integrated functionalities of self-cleaning, high transmittance, and alkali-induced self-enhancement can provide important solutions for maximizing the long-term power generation efficiency of photovoltaic glass in complex outdoor environments.

The development of efficient and economical photocatalysts is the focus of achieving sustainable remediation of water pollution. However, slow photogenerated carrier transfer and insufficient catalytic sites are the main reasons affecting photocatalytic applications. Herein, we developed flake-octahedral BiOBr/MIL-101(Fe) heterojunction catalysts through a facile solvothermal strategy for the degradation of pollutants under visible light irradiation. Scanning electron microscope, X-ray photoelectron spectrometer, Fourier infrared spectrometer, and X-ray diffraction analysis characterizations proved the successful synthesis of flake-octahedral BiOBr/MIL-101(Fe) heterojunction. Absorption spectra and Brunauer–Emmett–Teller analyses showed that the BiOBr/MIL-101(Fe) composites with an atomic percentage of Fe of 9.1 (denoted as BiOBr/MIL III ) had the optimal light absorption and the largest specific surface area. The BiOBr/MIL III achieved a remarkable Rhodamine B (Rh B) degradation efficiency of 94.5% within 60 min, with an apparent rate constant ( k ) of 0.03540 min −1 , demonstrating excellent visible light-driven photocatalytic activity. Photocatalytic mechanistic studies showed that the solvothermal-induced flake-octahedral BiOBr/MIL-101(Fe) III heterojunction promotes the formation of Z-scheme, which significantly enhances the carrier separation efficiency and accelerates the rapid generation of reactive radicals · O 2 − and h + . This work provides a feasible strategy for the construction of flake-octahedral inorganic-MIL photocatalysts with excellent photocatalytic performance.

The study aimed to characterize the regional histological architecture, collagen type I/III composition, and biomechanical properties of human dura mater to provide insights for the biomimetic design of dural repair substitutes. Dura from nine formalin-fixed cadavers were harvested from four anatomical regions: the cranial calvaria, skull base, cervical enlargement, and lumbosacral enlargement. Histological architecture and collagen type I/III composition were assessed using H&E and picrosirius red staining; elastic fibers were visualized with aldehyde fuchsin staining. Collagen type I/III contents were quantified by LC–MS/MS. Mechanical properties, including thickness, ultimate tensile strength, elastic modulus, elongation at break, and toughness, were determined by uniaxial tensile testing. Prototype patches were fabricated using a collagen type I/III blend and mechanically compared against those made from type I collagen alone using uniaxial tensile testing. Cranial dura exhibited four to five interwoven collagen lamellae, whereas spinal dura comprised three predominantly longitudinal layers. Low levels of collagen III were detected in both cranial and spinal dura. Cranial samples were dominated by collagen I with lower collagen III/I ratio, whereas spinal dura showed a relatively higher collagen III/I ratio, mainly attributable to lower collagen I content rather than an increase in absolute collagen III content. Elastic fibers were sparse in cranial dura, least abundant at the skull base, and most abundant in the lumbosacral region. Tensile tests showed that spinal dura had higher elastic modulus than the calvaria. The lumbosacral region exhibited greater tensile strength, elongation at break, and toughness than the calvaria, and higher tensile strength than the skull base. Correlation analyses suggested regional collagen subtype ratio and elastic fiber abundance were associated with elastic modulus. In the preliminary proof-of-concept tensile comparison, patches incorporating 20% type III collagen exhibited increased elongation at break and higher ultimate tensile strength than type I collagen-only control patches. Human dura mater displays pronounced site-dependent structure-composition-mechanics relationships. Regional variations in architecture, collagen type I/III ratio and elastin abundance help explain the distinct mechanical characteristics in cranial and spinal dura. The findings provide a basis for the design of biomimetic dural graft to improve repair outcomes.

Thyroid-associated ophthalmopathy (TAO) is a complex autoimmune inflammatory disease. There is an urgent clinical need for highly sensitive and minimally invasive biomarkers to enable early diagnosis and dynamic disease monitoring. Among them, miR-320a has been confirmed to be closely associated with oxidative stress regulation, fibroblast activation, and fibrosis progression. However, current detection methods, especially those based on real-time quantitative polymerase chain reaction (RT-qPCR), still suffer from cumbersome procedures, high instrumentation costs, and limited adaptability for rapid point-of-care diagnostics. To address this, we developed a nanozyme-assisted colorimetric biosensing platform integrating target-triggered probe hybridization with Co-g-C 3 N 4 , which exhibits enhanced peroxidase-like activity and stability. The method involves Co-g-C 3 N 4 synthesis, probe-nanozyme interface construction, catalytic optimization, and colorimetric detection via TMB oxidation, validated in spiked serum and with smartphone readout. The platform achieves sensitive miR-320a detection down to picomole levels with excellent linearity and specificity. In spiked human serum analysis, it reliably quantifies endogenous miR-320a with strong recovery rates (94.6-108.9%). However, we acknowledge that direct clinical validation using confirmed TAO patient samples is required for full diagnostic implementation, and this represents a limitation of the current study. Generally speaking, this work provides a portable, cost-effective, amplification-free colorimetric nanozyme platform for miRNA detection, requiring only basic laboratory equipment, and holding significant promise for point-of-care precision diagnostics in autoimmune and fibrotic diseases.

N/NS co-doping boosts PAA activation, removing 97.5% sulfonamides in 30 min. • EPR and electrochemistry verify dual-channel degradation dominated by 1 O 2 . • DFT confirms 1 O 2 -induced N-S scission and ring opening mitigate toxicity. • DOM-antibiotic complexation negligibly impacts degradation efficiency. Element-doped biochar has emerged as an effective catalyst for activating peracetic acid (PAA) toward antibiotic degradation. However, the electron transfer processes occurring at the biochar interface remain insufficiently understood. In this study, N-doped biochar (NBC) and N/S co-doped biochar (NSBC) are employed to efficiently degrade sulfonamide antibiotics through PAA activation. Active sites, including pyridinic N, thiophene S, and graphitic defects, synergistically promote PAA activation, preferentially generating singlet oxygen ( 1 O 2 ) accompanied by •OH and O 2 •− . Radical and non-radical pathways operate simultaneously, resulting in an average removal efficiency of 97.45% for the target sulfonamides within 30 min. Quenching experiments, electron paramagnetic resonance, and electrochemical analyses collectively confirm the dual-pathway activation mechanism. Liquid chromatography-mass spectrometry combined with density functional theory calculations reveals that the main transformation pathways involve S N bond cleavage, aromatic ring opening, and hydroxylation reactions. Toxicity prediction and plant growth assays further demonstrate a significant reduction in the overall toxicity of the degradation intermediates. In addition, dissolved organic matter released during the biochar reaction process forms complexes with sulfonamide antibiotics, although these interactions are insufficient to substantially affect antibiotic degradation efficiency. Overall, this study not only elucidates the multi-channel activation mechanism of the NBC/NSBC-PAA system but also provides experimental support for the practical application of biochar-based catalytic systems in water purification.

An ultrasensitive biosensor has been developed for miR-375 detection. • HRP is embedded into COFs to form stable HRP@COFs co-precipitated nanospheres. • The HRP@COFs preserved enzymatic activity and enhanced catalytic efficiency. • The biosensor has been successfully validated using clinical samples. The dysregulated expression of microRNA (miRNA) in various cancers has attracted considerable attention owing to their crucial roles in tumor initiation and progression. Among them, miR-375 has been recognized as a prospective biomarker for early malignancy detection and therapeutic monitoring. In this study, a highly sensitive electrochemical biosensor has been developed based on horseradish peroxidase (HRP)-embedded covalent organic framework (HRP@COFs) co-precipitated nanospheres for the detection of miR-375. The HRP@COFs nanocomposite effectively preserves the enzymatic activity of HRP while providing the structural stability and high loading capacity of COFs, thereby enhancing catalytic efficiency and signal amplification. In the presence of target miR-375, the azide-modified H1 hairpin probes on the HRP@COFs surface are activated, leading to the formation of a rigid H1-H2 duplex structure through competitive hybridization with H2 hairpins. The resulting H2-H1-HRP@COFs complexes are subsequently anchored onto the electrode surface via click chemistry. Upon the addition of H 2 O 2 , HRP catalyzes aniline polymerization and deposition, resulting in a significant electrochemical response. This biosensor achieves ultrasensitive detection of miR-375 with a detection limit as low as 230 aM. It has been successfully validated using clinical samples, demonstrating great potential for reliable breast cancer diagnosis. This work highlights the synergistic advantages of integrating HRP with COFs, providing a robust and efficient platform for microRNA detection and expanding the applications of COFs-based materials in biosensing and clinical diagnostics.

The WPU matrix promotes fungal growth, spore germination, and tolerance to UV, thermal, and chemical stresses. • WPU enhances conidial retention on maize leaves and improves insecticidal efficacy. • WPU-encapsulated conidia evade host immune recognition, reducing immune clearance and facilitating infection. • Transcriptomic analysis identified key genes and pathways associated with WPU-mediated growth promotion and UV resistance. Environmental fragility and host immune clearance remain major barriers to the field efficacy of entomopathogenic fungi in agricultural pest management. In this study, we developed a bio-based nanocarrier using self-assembled, castor oil-derived waterborne polyurethane (WPU) to encapsulate Beauveria bassiana conidia. The resulting WPU nanodispersion (∼34.8 nm) formed a stable coating on the conidial surface through interfacial self-assembly. Encapsulation significantly improved conidial germination and fungal development while enhancing tolerance to ultraviolet irradiation, thermal stress, and chemical stress. Maize phylloplane assays showed that the WPU matrix acted as an adhesion-promoting coating, substantially increasing rainfastness and environmental persistence. Functional assays and microscopic observations indicated reduced hemocyte recognition and phagocytic clearance of WPU-coated conidia, suggesting attenuated early immune elimination during infection. Comparative transcriptomic analysis of encapsulated and unencapsulated conidia under basal and UV-stress conditions revealed differential expression of genes associated with DNA repair, antioxidant defense, and cuticle-degrading enzyme activity, indicating stress-related transcriptional changes. Overall, these results suggest that castor oil-based WPU functions both as a protective coating and as a biologically interactive matrix. This study provides mechanistic insight into polymer-mediated enhancement of entomopathogenic fungi and offers a practical framework for developing high-performance, environmentally stable mycoinsecticide formulations.

3DOM-TiO 2 /CuO S-scheme heterojunction synthesized via hard templating • Removes 99.06% U(VI) in 120 min; capacity of 1751.33 mg/g • Dynamic Cu valence change & O-vacancy evolution restrain charge recombination. • In situ multi-spectra & DFT reveal charge transfer and U(VI) reduction mechanism. Photocatalysis offers a sustainable approach for uranium-containing wastewater remediation, yet conventional materials still suffer from limited solar-light utilization and rapid charge recombination. Herein, a three-dimensional ordered macroporous TiO 2 /CuO composite (3DOM-TC) was synthesized using resorcinol–formaldehyde resin spheres as a hard template. The ordered macroporous TiO 2 framework enables slow-photon-assisted light harvesting and multiple light scattering, while CuO coupling broadens the light-response range and constructs an S-scheme TiO 2 /CuO heterojunction to promote directional charge separation. Meanwhile, oxygen vacancies mainly serve as electron-trapping and O 2 /intermediate adsorption–activation sites, which are coupled with the dynamic Cu 2+ /Cu + variation during photocatalysis. As a result, 3DOM-TC achieves 99.06% U(VI) removal within 120 min, corresponding to a maximum extraction capacity of 1751.33 mg/g. Photoelectrochemical tests confirm enhanced photocurrent density and efficient interfacial charge transport compared with pristine TiO 2 . In situ EPR, XPS, and DFT calculations reveal the photoinduced charge-transfer pathway and illumination-enhanced oxygen-vacancy signals. Moreover, in situ FTIR spectroscopy confirms that photogenerated ·O 2 − can further convert to H 2 O 2 -related species, thereby promoting U(VI) precipitation as (UO 2 )O 2 ·4H 2 O. This work highlights the synergistic integration of 3DOM-enabled light harvesting, S-scheme charge separation, and vacancy-assisted electron transfer and O 2 activation, providing a promising strategy for efficient photocatalytic U(VI) sequestration.

With the acceleration of industrialization, oily wastewater poses a serious threat to the ecological environment. Membrane separation technology has emerged as a research hotspot due to its advantages of high efficiency and energy savings; however, membrane fouling significantly restricts its long term stable operation. This study introduces a 3D COFs/MXene composite membrane with photocatalytic self–cleaning capability for highly efficient oil–water separation. A well dispersed 3D COFs colloidal dispersion was prepared via oil–oil–water three phase interfacial polymerization, effectively overcoming the dispersion challenges of COFs materials. Ti 3 C 2 T x MXene nanosheets were synthesized using the LiF/HCl etching method. Using intermolecular hydrogen bonding, the two components were ultrasonically assembled, and a COFs/MXene composite membrane was fabricated via vacuum assisted filtration. The membrane exhibits excellent hydrophilicity (water contact angle as low as 54.3°) and underwater oleophobicity (underwater oil contact angle up to 144.9°). Under visible light irradiation, the MXene component generates reactive oxygen species (·O 2 − and ·OH), enabling photocatalytic degradation of oil contaminants adsorbed on the membrane surface and thereby imparting self–cleaning functionality. Separation performance tests reveal that the composite membrane achieves efficient separation of various oil–in–water emulsions, with a maximum water flux of 1918.9 L m −2 h −1 bar −1 . The flux for n –hexane emulsion increased to 2.1 times that of pure MXene membrane, while maintaining a rejection rate above 98.8%. Moreover, the membrane demonstrates excellent cycling stability and photocatalytic antifouling performance. This research offers a novel strategy for developing self–cleaning separation membranes and holds promising potential for application in oily wastewater treatment.
