The coexistence of high-value pigment copper phthalocyanine (CuPc) and synthetic dyes in textile wastewater presents a dual challenge of environmental pollution and resource wastage. Herein, a novel singlet oxygen ( 1 O 2 )-dominated self-derived catalytic system was developed to simultaneously degrade rhodamine B (RhB) and recover valuable CuPc. Instead of requiring of the addition of external catalysts, wastewater-borne CuPc acted as an efficient heterogeneous activator for peroxymonosulfate (PMS). The system achieved 93.1% RhB removal within 30 min with an apparent rate constant of 0.089 min −1 , significantly outperforming the individual systems. Mechanistic studies combined with theoretical calculations revealed that the unique Cu-N 4 active sites facilitated PMS activation to generate 1 O 2 as the primary reactive oxygen species. This 1 O 2 -dominated pathway enabled the selective oxidation of electron-rich RhB while preserving the electron-deficient CuPc macrocycle, resulting in an over 80% recovery yield of CuPc. The system exhibited robust performance across a wide pH range (3.0-11.0) and in the presence of interfering anions. Moreover, the practical applicability of the system was further validated in simulated textile wastewater. This work provides a cost-effective, waste-derived catalytic strategy for complex textile wastewater treatment, promoting both pollution control and circular resource recovery.

The primary limitations of the oxygen evolution reaction (OER) electrocatalysts stem from poor electrical conductivity and insufficient accessibility of active sites. So highly productive catalysts are vital to lower the overpotential and enhance the kinetics of the sluggish OER. In this work, we present an effective OER electrocatalyst (NiS/N-CNT@Ni) and composites of Ni nanoparticles encapsulated in NiS/N-CNT fabricated via a simple two-step thermal treatment method. Meanwhile, due to the synergistic effect between NiS and nitrogen-doped carbon nanotubes (CNTs) and Ni, the NiS/N-CNT@Ni composites show higher OER electrocatalytic activity and better durability than commercial RuO 2 catalysts. Compared to commercial RuO 2 , the NiS/N-CNT@Ni catalyst demonstrates a lower overpotential (313 mV at 10 mA cm −2 ) and better stability. This study confirms that the NiS/N-CNT@Ni material not only exhibits a low overpotential but also presents a scalable, cost-effective synthesis strategy for high-performance composites applicable to energy conversion and storage.

Effective repair of large bone defects poses a major clinical challenge. Traditional 3D printed polyetheretherketone (PEEK) scaffolds provide customized structures and mechanical adaptability. However, their biological inertness and lack of dynamic bioactive microenvironment limit vascular regeneration and osteogenic differentiation, ultimately limiting overall bone regeneration. This study combined photothermal responsive black phosphorus nanosheets (BPNSs) with strontium ions (Sr 2+ ), and further modified the combination with polydopamine (PDA) to construct ‘PDA@BP-Sr Nanocomposites’; subsequently a photo responsive biomimetic porous PEEK scaffold (PEEK-PDA@BP-Sr, PPBS) was developed. Under near-infrared light-induced controllable mild photothermal conditions (40-42 °C), this porous scaffold enables the time-dependent release of bioactive ions, significantly promoting the proliferation, migration, and tube formation of human umbilical vein endothelial cells (HUVECs). Moreover, it activates the ERK1/2 signaling pathway by upregulating HSP70 expression, effectively regulating the osteogenic differentiation of rat bone marrow mesenchymal stem cells (rBMSCs) in vitro. In a rabbit femoral defect model, in-vivo experiments further confirmed that NIR light irradiation enables the PPBS scaffold to dynamically regulate the vascularization bone formation coupling. This promotes early vascularization and bone regeneration, significantly accelerating bone defect repair. This study successfully developed a novel bone repair scaffold that combines structural biomimicry, mechanical adaptation, and efficient biological activity. Additionally, the study also provides important technical support for bone defect repair under conditions of insufficient blood supply.

MSAMD is composed of a composite of nanofibers and microneedles. • MSAMD integrates multiple functions into a single platform. • MSAMD exhibits antibacterial activity against E. coli , S. aureus , and MRSA. • MSAMD facilitates the unidirectional drainage of inflammatory exudates. • MSAMD monitors wound pH to assess the healing status of infected wounds. Infected diabetic wounds face multiple challenges, including bacterial infection, uncontrolled inflammation, and impaired angiogenesis, leading to prolonged wound healing. However, traditional dressings for infected diabetic wounds lack effective antibacterial properties, cannot manage inflammatory exudate, or cannot monitor healing in real time. Hence, we propose a pH-monitoring self-pumping antibacterial microneedle dressing that simultaneously provides antibacterial activity, inflammatory exudate management, and wound status monitoring. The dressing consists of a pH-monitoring absorbent layer, an adhesive drainage layer, and an antimicrobial microneedle layer. The first two layers form a pH-monitoring self-pumping backing layer. The microneedle layer of this dressing punctures the MRSA biofilm in diabetic wounds and eradicates MRSA. The dissolved microneedle tips drain inflammatory exudate into the pH-monitoring self-pumping backing layer, where unidirectional drainage enables exudate removal and pH colorimetric monitoring to assess wound healing status. In MRSA-infected diabetic wound healing experiments and immunofluorescence analyses, this dressing demonstrates excellent antibacterial activity, inflammatory regulation, and vascular regeneration. This multifunctional integrated dressing offers a novel treatment paradigm for infected diabetic wounds.

The high theoretical specific capacity and natural abundance of Fe 2 O 3 render it an appealing choice for utilization as an anode material in asymmetric supercapacitors (ASCs). The material's path to practical adoption, however, is plagued by inherent limitations, including low intrinsic conductivity and substantial volume variation during charge-discharge processes. To overcome these issues, this work synthesized a Co 2+ -doped Fe 2 O 3 composite (CMF) using a metal-organic framework (MOF) as a sacrificial template. The MOF-derived Fe 2 O 3 possesses a highly ordered and tunable pore architecture, thereby enabling swift diffusion and migration of electrolyte ions. Furthermore, introducing Co 2+ into the Fe 2 O 3 lattice generates many oxygen vacancies and crystal defects, greatly boosting its intrinsic conductivity, ion migration, and structural stability. Electrochemical characterization demonstrated that the optimized 2 wt% CMF electrode yielded a high specific capacity of 226.1 mAh g −1 at 1 A g −1 . When configured into an AC//2 wt% CMF asymmetric supercapacitor, the device recorded an energy density of 43.1 Wh kg −1 at a power density of 350 W kg −1 . Notably, the assembled device also exhibited outstanding cycling durability, retaining 96.4% of its initial capacity after 20,000 cycles at 2 A g −1 . The practical capability of the device was demonstrated by powering a light-emitting diode (LED), highlighting its potential for real-world applications.

Biomimetic hydrogels, with their excellent biocompatibility and tissue adaptability, have garnered significant attention in the field of wound repair. Dual-layer hydrogels can simultaneously achieve hemostasis and anti-adhesion, demonstrating notable potential for application in liver resection surgery. However, existing systems suffer from insufficient mechanical properties and wet adhesion capabilities, and their efficacy in promoting liver wound healing is limited, severely hindering their clinical translation. To address the complex microenvironment of post-liver resection wounds, this study developed a dual-layer functional hydrogel (DAR@Glu) comprising an anti-adhesion layer (AAL) and a repair layer (RL). Through the synergistic interaction of interfacial water regulation and a multi-hydrogen-bond network, this material combines stable wet adhesion with anti-adhesion properties: the repair layer achieves strong wet adhesion via dynamic covalent bonds and hydrogen bonds, while the introduction of glutamic acid further enhances liver tissue repair activity; the anti-adhesion layer forms a dense hydrated layer that effectively prevents tissue adhesion. In vitro experiments confirmed that DAR@Glu can stably adhere to a 1.5 kg weight underwater, demonstrating excellent mechanical properties and sustained wet adhesion. In a rat partial liver resection model, the introduction of glutamic acid significantly enhanced liver tissue repair efficacy. Postoperative day 7 regional quantitative immunohistochemical analysis of liver tissues showed that in the focal regenerative region at the hydrogel-adjacent liver wound edge, the positive staining levels of Cyclin D1, Ki67 and PCNA in the DAR@Glu group were all significantly increased compared with the control group.The CD68 positivity rate was the lowest, while the hydrogel also demonstrated good hemostatic effects; in a cecal injury model, this hydrogel effectively inhibited intra-abdominal adhesions. Therefore, DAR@Glu can efficiently promote wound healing, hemostasis, and anti-adhesion after liver resection, providing an innovative strategy for the clinical repair of liver injuries.

Liquid-metal-assisted annealing enables in situ growth of vertically aligned graphene on diamond. • Structural evolution from discontinuous graphene domains to continuous shells forms interconnected sp 2 networks and heterointerfaces. • Optimized G@D-2 exhibits RL min of −42.89 dB, EAB of 4.43 GHz, and TC of 25.99 W m −1 K −1 . Highly integrated and miniaturized electronic systems impose concurrent demands on efficient thermal management and electromagnetic interference suppression. Diamond possesses ultrahigh thermal conductivity, yet its poor impedance matching and limited loss mechanisms result in insufficient electromagnetic wave absorption. Here, we report a structural regulation strategy based on complementary coupling of carbon allotropes to address this issue. A vertically aligned graphene shell is in-situ constructed on artificial diamond particles via liquid-metal-assisted annealing, forming a core-shell graphene@diamond (G@D) heterostructure with tunable interfacial hybridization. The structural evolution from discontinuous graphene domains to a continuous shell establishes a continuous sp 2 conductive network and heterogeneous interfaces. As a result, both impedance matching and dielectric loss are optimized simultaneously. The optimized material exhibits a minimum reflection loss of −42.89 dB and an effective absorption bandwidth of 4.43 GHz. Mechanistically, the excellent performance is mainly attributed to the synergistic effect of conductive loss, interface polarization and multiple scattering, which is determined by the evolution of interface continuity and the modulation of sp 2 /sp 3 hybridization ratio. Meanwhile, the formation of continuous interfacial thermal pathways effectively suppresses phonon scattering, leading to a high thermal conductivity of 25.99 W m −1 K −1 in the polymer matrix (7.5 times that of the physically mixed system). This work provides a general paradigm for integrating electromagnetic attenuation and thermal transport within a single filler system, offering new opportunities for multifunctional materials in high-power electronics and advanced packaging.

A KGM/CMC/PVA film loaded with a hydroxypropy-β-cyclodextrin/hesperetin (HP-β-CD/HES) inclusion complex was developed for strawberry preservation. The inclusion complex showed an encapsulation efficiency of 70.41 ± 4.01%. Loading the inclusion complex enhanced the barrier and bioactive properties of the films. At the better loading level (KCP-HH3, 1.5%), the film provided nearly complete UV shielding at 200–350 nm and showed a transmittance of approximately 21% at 800 nm. Relative to KCP, KCP-HH3 exhibited lower water vapor permeability (0.69 ± 0.06 g·mm/(m2·h·kPa)) and oxygen permeability (0.066 ± 0.006 g·mm/(m2·h·kPa)). The cumulative HES release from KCP-HH3 reached 82.43 ± 2.19% after 7 days at 98% relative humidity. KCP-HH3 scavenged 78.19 ± 3.71% of DPPH radicals and 88.89 ± 4.30% of ABTS radicals. It also inhibited Escherichia coli (91.18 ± 2.99%), Staphylococcus aureus (79.21 ± 3.45%), and Aspergillus niger (92.85 ± 2.75%). This highest-loading formulation delivered the best overall strawberry-preservation performance. After 12 days of storage, strawberries packaged with KCP-HH3 showed higher firmness (0.89 ± 0.04 N) and total soluble solids (7.96 ± 0.21%), as well as lower weight loss (14.30 ± 0.40%), than the polyethylene control, which showed a firmness of 0.42 ± 0.05 N, total soluble solids of 6.22 ± 0.20%, and weight loss of 16.36 ± 0.66%. These results support the potential of HP-β-CD/HES-loaded KCP films as biodegradable active packaging for fruit preservation.

Selective separation of dyes and inorganic salts is central to dyeing effluent treatment and resource recovery. However, the rejection mechanisms of low-molecular-weight dyes and the reliability of membrane performance evaluation under realistic conditions remain insufficiently understood. Here, the separation behaviors of representative dyes, Methyl Orange (MO) and Congo Red, were systematically investigated using a dense nanofiltration (NF) membrane and a tight ultrafiltration (UF) membrane, combining experiments and molecular simulations. Results reveal that dye aggregation critically governs apparent membrane selectivity. At high concentrations, dyes form J- or H-type aggregates through π–π stacking and electrostatic interactions, increasing their hydrodynamic size and markedly enhancing the rejection of otherwise permeable small dyes by the UF membrane. Disruption of aggregation by ethanol addition, elevated ionic strength, or reduced pH diminishes size-sieving and electrostatic effects, leading to substantial rejection decline, particularly for the UF membrane. In addition, electrostatic adsorption of cationic dyes and pore blockage induced by anionic dyes further affect flux stability. When treating real dyeing effluent, the UF membrane exhibits significantly reduced rejection of low-concentration, weakly aggregated dyes, whereas the NF membrane maintains dye rejection but suffers from excessive salt rejection. Guided by these insights, a dense NF membrane with a heterogeneous charge architecture was fabricated via interfacial polymerization. The membrane, with a molecular weight cut-off of 235 Da, integrates a weakly negative surface and internally distributed positive microdomains, enabling high MO rejection with relatively low Na 2 SO 4 rejection. This work demonstrates that dye aggregation can induce overestimation of membrane selectivity and highlights the necessity of evaluating intrinsic rejection capability toward small-molecule dyes under realistic conditions.

The early and accurate detection of carcinoembryonic antigen (CEA) is critical for cancer diagnosis and prognosis. Herein, we report a novel label-free electrochemical impedimetric immunosensor based on the intrinsic electron-blocking effect of wide bandgap perovskite type BiCoO₃ nanosheets (BiCoO₃ NSs) for the ultrasensitive detection of CEA. The BiCoO₃ NSs were synthesized via a facile hydrothermal method followed by calcination, exhibiting a defined hexagonal flakelike morphology with a large specific surface area for efficient antibody immobilization. Leveraging its wide bandgap (~ 4.2 eV) and n-type semiconducting nature, the BiCoO₃ modified electrode significantly hinders interfacial electron transfer, enabling remarkable signal amplification without the need for noble metal modification. Under optimized conditions, the proposed immunosensor exhibits an ultralow detection limit of 0.01 pg mL⁻¹, a wide linear range (50 fg mL⁻¹ to 1.0 µg mL⁻¹), high sensitivity, and excellent selectivity. The sensor demonstrates satisfactory accuracy in human serum analysis with recoveries exceeding 97%, highlighting its great potential as a reliable and cost effective platform for clinical CEA monitoring and early cancer diagnostics.

Bioorthogonal catalysis holds great promise for precision cancer therapy, yet its clinical translation is critically hindered by the lack of reliable control over catalytic activity. Uncontrolled “always-on” catalysis or irreversible activation prevents timely termination, making it difficult to confine prodrug activation within a safe therapeutic window. To address this challenge, we developed an ultrasound-recharging-regulated closed-loop bioorthogonal system integrating on-demand activation, enhanced catalytic performance, and self-termination, enabling precise in vivo prodrug activation. Mechanistically, pyroelectric polarization of BaTiO 3 induces deposition of sub-nanometer Pd clusters whose catalysis is initially silenced by rapid oxidative passivation. Upon ultrasound stimulation, the piezoelectric BaTiO 3 core generates a built-in electric field that reduces surface Pd 2+ to catalytically active Pd 0 , thereby activating bioorthogonal reactions while promoting charge separation and reactive oxygen species generation. Simultaneously, piezoelectric screening charges accelerate interfacial electron transfer, significantly enhancing catalytic kinetics. Crucially, rapid repassivation after ultrasound cessation leads to complete catalytic deactivation, establishing a closed bioorthogonal cycle following a single stimulus. In vitro and in vivo studies demonstrate that the activated species induce immunogenic cell death while avoiding side effects from persistent catalysis. This work presents a safe, controllable, and efficient paradigm for bioorthogonal catalytic therapy, advancing its clinical translation.

Background Chronic inflammation and impaired immune microenvironment are key barriers to effective cartilage regeneration. Herein, we developed an integrated, injectable thermosensitive hydrogel system termed CS@Gel-Mg. This system modularly combines exosome-loaded chitosan microspheres (CM@Exo) embedded within a Mg 2+ -coordinated poly(N-isopropylacrylamide)-based ionic liquid hydrogel (Gel-Mg), aiming to modulate local immune response and promote cartilage repair. Methods Hydroxypropyl-modified chitosan microspheres were synthesized via emulsion crosslinking and effectively loaded with bioactive exosomes. The Gel matrix was fabricated using an ionic liquid monomer (IL-C4) copolymerized with NIPAM and N-vinylimidazole, followed by Mg 2+ complexation. Physicochemical properties, including morphology (SEM/TEM), surface chemistry (XPS/FTIR), and thermoresponsive behavior (DSC/TGA), were systematically characterized. The effects of CS@Gel-Mg on immune and cartilage regeneration were evaluated in vivo and in vitro using Western blot, qPCR, histological staining, flow cytometry, gait analysis, and asymmetric weight-bearing analysis. Results In vitro, the system demonstrated excellent cytocompatibility, promoted ATDC5 cell proliferation and migration, and inhibited apoptosis. The hydrogel also reprogrammed macrophage polarization from M1 to M2 phenotype, as confirmed by qPCR and flow cytometry. In vivo, using a rat full-thickness cartilage defect model, CS@Gel-Mg exhibited improved weight-bearing function, reduced inflammatory infiltration, and superior cartilage histological scores compared to control groups. Mechanistically, immunofluorescence and Western blot analyses suggested enhanced expression of SOX9, COL2A1 and COL1A1, along with suppression of inflammatory cytokines. Furthermore, SOX9 knockdown in vivo diminished the therapeutic effect, confirming its regulatory role in the immuno-chondrogenic axis. Conclusion This exosome-integrated thermoresponsive hydrogel provides a multifunctional platform for immune modulation and cartilage regeneration. Our findings highlight the potential of CS@Gel-Mg as a promising therapeutic strategy for osteochondral repair.
