Oxygen-vacancy TiO 2 was prepared via inert-atmosphere annealing. • TA-Ce metal-phenolic network was deposited on micro-arc oxidized Ti. • Coatings showed enhanced near-infrared photothermal antibacterial activity. • Coatings scavenged ROS and promoted osteogenic differentiation. Titanium-based implants are widely used for bone repair but still face challenges including bacterial infection, oxidative stress, and insufficient osseointegration. In this study, a tannic acid-cerium (TA-Ce) metal-phenolic network was deposited onto an oxygen-vacancy-rich micro/nano-structured TiO 2 coating to construct a bioactive titanium surface. The coating was fabricated through micro-arc oxidation, alkali-heat treatment, inert-atmosphere annealing, and subsequent TA-Ce deposition. Oxygen vacancies enhanced near-infrared (NIR) absorption and photothermal conversion, while the TA-Ce network further improved photothermal responsiveness and antioxidant activity, under 808 nm NIR irradiation, the modified coating exhibited excellent photothermal antibacterial performance against both Staphylococcus aureus and Escherichia coli . In addition, the coexistence of Ce(Ⅲ)/Ce(Ⅳ) and phenolic groups enabled efficient reactive oxygen species scavenging, reducing extracellular and intracellular oxidative stress. In vitro studies further demonstrated favorable cytocompatibility and enhanced osteogenic differentiation, including increased alkaline phosphatase activity, collagen secretion, and mineralization. Overall, this study provides a simple and effective strategy for developing titanium implant surfaces with combined antibacterial, antioxidant, and osteogenic properties, offering new insights into multifunctional implant design.

Litchi
( L. chinensis Sonn.) is a
perishable fruit that is vulnerable to oxidative browning and fungal
infection. Herein, ferulic acid and natamycin were chosen as the antioxidant
and antimycotic agents, respectively. To improve their water solubility,
we used CD-MOF-1 to encapsulate ferulic acid. Meanwhile, natamycin
was encapsulated with gum arabic and pullulan. The most homogeneous
and stable natamycin nanocapsules were fabricated through stirring
0.5 mg/mL natamycin using 2.5% (w/v) gum arabic-pullulan (1:1, w/w,
1.25% each) in water. The main encapsulation mechanisms of ferulic
acid and natamycin were electrostatic interactions between the carboxyl
groups of ferulic acid and K + ions from CD-MOF-1 and hydrophobic
interactions between the macrocyclic lactone ring of natamycin and
the protein part of gum arabic, respectively. In addition, pullulan
was indispensable for stabilizing natamycin. The antioxidant and antifungal
composite sol presented 99.85% oxidation inhibition and 79.06% mycelial
growth inhibition and effectively delayed the oxidative browning and
fungal decay on litchi pericarps.

Argan nutshell lignin (ANS-LIG) is a sustainable biomaterial recognized for its notable antioxidant and antimicrobial properties. This study investigates its application in 3D-printed (3DP) wound dressings, infused with Moroccan essential oils (EOs), specifically Mentha pulegium (MPEO) and Rosmarinus officinalis (ROEO), to reinforce its antibacterial efficacy. ANS-LIG and EOs were integrated into Eudragit RS PO (EudRP) matrices and printed at room temperature to protect the bioactive properties. Analyses using SEM, ATR-FTIR, and XRD revealed the formation of highly porous, lightweight meshes, with ANS-LIG crystallographic planes becoming partially amorphous when combined with EUD and EOs. Thermal analysis demonstrated improved stability for LIG/EUD + EOs compared to LIG/EUD alone. Studies on hydrophilicity and swelling indicated substantial water absorption, while DPPH assays confirmed strong antioxidant activity within 15 min. Antibacterial tests against gram-positive and gram-negative bacterial strains demonstrated significant activity; in particular, Staphylococcus aureus viability was reduced by 93% after 24 h using the LIG/EUD+MPEO 3D printed patch. Lastly, for the in vitro biocompatibility assay, mouse dermal fibroblasts (MTT assay) were utilized, confirming promising cytocompatibility, with ROEO-loaded meshes exhibiting the highest cell viability of 220%, while MPEO demonstrated more efficient antimicrobial results across all tested strains. Ultimately, the obtained 3D-printed scaffolds efficiently integrated sustainable biopolymers mixed with potent antimicrobials and antioxidant agents, alongside impressive biocompatibility, indicating their potential as advanced wound dressings. This study underscores the advantages of incorporating ANS-LIG and EOs into 3D-printed formulations for future biomedical applications. Graphical abstract

Longhu Pagoda, a national key cultural heritage site located at the southern foot of Hushan Mountain in Liubao, Jinan, Shandong Province, is a masterpiece of Tang-dynasty stone pagoda architecture and a core component of the Shentong Temple heritage complex alongside the Four Gates Pagoda. The pagoda features a distinctive “Tang-dynasty body, Song-dynasty crown” structure: its stone base and main body, carved with intricate high-reliefs of dragons, tigers, heavenly kings, arhats, and apsaras, date back to the late Tang Dynasty (717–845 AD), while the brick eaves and roof were reconstructed during the Northern Song Dynasty. Severely threatened by biodeterioration induced by bryophytes, lichens, and associated microorganisms, the pagoda’s exquisitely carved stone surface has undergone irreversible aesthetic degradation and structural weakening, threatening its thousand-year-old artistic integrity. Biocide treatment is a commonly adopted strategy for stone heritage conservation. This study aims to characterize the specific biodeteriogens colonizing Longhu Pagoda and evaluate the efficacy of various biocides for targeted conservation intervention. In this study, biological samples collected from Longhu Pagoda were first identified: bryophyte samples contained chloroplasts, with some having morphological characteristics similar to Pottiaceae or Grimmiaceae; symbiotic algae isolated from lichen samples were identified asChlorellasp.; four dominant fungal strains were isolated via morphological observation and molecular sequencing (ITS), namelyAspergillus niger(F1),Trichoderma yunnanense(F2),Talaromyces ruber(F3), andAspergillus aflatoxiformans(F4). On this basis, the inhibitory effects of different biocides on dominant deteriorating organisms were systematically evaluated via chlorophyll fluorescence analysis, algal growth inhibition tests, and oxford cup assays, combined with field verification on Longhu Pagoda. The optimal biocide with stable inhibition efficacy and favorable stone compatibility was screened out. The results provide technical support for the biological conservation of Longhu Pagoda and similar stone cultural relics suffering from microbial biodeterioration.

Hydrophobic coatings have been demonstrated to provide effective temporary self-cleaning protection for buildings and artifacts. However, deficiencies in multiple antifouling properties and environmental adaptability hinder the application. Herein, a PDMS/SiO 2 /TiO 2 /Bi 2 SiO 5 /Bi 12 SiO 20 (STB) coating with adhesive matrix-photonic crystal-light driven antifouling composite structure was constructed for multifunctional antifouling protection, which exhibited balanced superhydrophobicity, UV-resistance, antimicrobial, antifouling and self-revealing properties. The coating integrated bonding agent, photonic crystal microspheres and micrometer particles-islands. The bonding agent (PDMS) endowed the coating with a controlled morphology, excellent mechanical properties and favorable environmental adaptability. The photonic crystal layer enhanced the utilization of weak incident light by generating light scattering centers and nonlinear optical effects, which resulted in a coating with excellent UV reflectivity (98 %) while maintaining excellent light-driven stain resistance. This effect resolved the conflict between UV protection and light-driven stain resistance of the coating. Furthermore, the optimal surface roughness of micrometer particle-islands ( R a = 36.5 nm) provided excellent superhydrophobicity (contact angle = 156.5° ± 1.4°, roll-off angle = 5° ± 0.6°), while it also utilized Bi (3−X)+ and oxygen vacancies (O V ) to enhance the light-driven antimicrobial ( Escherichia coli for 99.0 %, Staphylococcus aureus for 99.3 %) and antifouling activity (Rhodamine B for 96.6 %) of the coating. This study demonstrated a successful balance of desirable properties in antifouling protective coatings and provided a novel strategy for the preparation of temporary protective coatings for buildings and artifacts with multifunctional, all-in-one and self-cleaning properties.

Cellulose nanocrystals (CNCs) are one of the most important biomass-derived materials for reinforcing hydrogels. Nevertheless, there is a lack of comparative studies examining the impact of CNCs synthesized via disparate methodologies on the toughening of hydrogels. This study synthesized two different CNCs through the sulfuric acid hydrolysis and deep eutectic solvent (DES) synthesis methods from Gleditsia sinensis peel, a forest residue, and compared their effects on the enhancement of the mechanical properties of SA/PAAM (sodium alginate/polyacrylamide) hydrogels. The comprehensive characterizations demonstrated that the mechanical properties of hydrogels derived from DES-CNCs are superior to those derived from S-CNCs (sulfuric acid-CNCs). The DES-CNC/SA/PAAM hydrogels revealed a homogeneous structure with excellent strain (2534%), high transparency (90%), and self-adhesiveness (15 kPa). The flexible sensor assembled using hydrogels exhibited accurate real-time monitoring capabilities for minor and larger strains during movement. To investigate the enhancement mechanism of CNCs on hydrogels, this work evaluated weak interaction forces between DES-CNC/SA/PAAM components through the quantum chemical theoretical calculations, with the combination of wave function analysis method and Molecular dynamics (MD) simulation. This work provides comparative tests of forestry biomass sources in hydrogel synthesis and sensing applications and suggests a new idea for high-value utilization of biomass feedstocks.

As one of the most common medical dressings, imparting effective antibacterial properties to cotton (COT) fabric is a crucial strategy for preventing bacterial infections. To achieve the continuous release of silver ions, a novel one-step hydrothermal approach was developed by integrating reduced graphene oxide (rGO) and silver nanoparticles (AgNPs) into the fabric, resulting in the in situ growth of rGO/Ag aerogel on the surface of the cotton fabric (rGO/Ag/COT), and forming a new type of structured medical antibacterial dressing. Various analytical methods (including SEM, XRD, plate counting method, flow cytometry, and cytotoxicity) were employed to investigate the structure and properties of the rGO/Ag/COT dressing. The results indicated that, the rGO/Ag aerogel has been embedded within COT fabric via ester-based bonding. The rGO/Ag/COT dressing demonstrated a remarkable antimicrobial efficacy of 99.9% against Escherichia coli and Staphylococcus aureus, owned the ability to continuously release silver ions over a period of several days, and generated a significant amount of reactive oxygen species within the bacterial cells. Additionally, the rGO/Ag/COT dressing displayed the in vitro cytotoxicity of grade 1 and excellent biocompatibility. These implied this strategy provides more ideas for the field of medical dressings through the combination of aerogels and textiles.

Flexible pressure sensors are critical components in next-generation wearable electronics and intelligent human-machine interface (HMI). However, conventional designs often suffer from limited sensitivity and uniaxial force detection, restricting their applicability in complex environments. Here, a bioinspired omnidirectional iontronic sensor (BOIS) is presented, engineered via triboelectric coupling and featuring a cross-scale architecture inspired by the spatial encoding properties of cochlear cilia. Through the integration of a 70° inclined macroscopic ciliary array based on Fibonacci helix optimization and 3D printing technology, the sensor achieves high-resolution detection of both normal and shear forces. The incorporation of iontronic effects further enhances sensitivity via synergistic charge modulation. The resulting flexible sensing platform demonstrates excellent mechanical compliance, multi-axis responsiveness, and high precision in monitoring dynamic joint motions such as wrist bending and finger flexion. This work offers a robust strategy for advancing omnidirectional tactile sensing, with promising applications in medical rehabilitation, soft robotics, and HMI.

Invasive pest Spodoptera frugiperda , known as the fall armyworm (FAW), evolves rapid resistance to chlorantraniliprole (CAP) via symbionts, reducing traditional control efficacy and causing economic losses. To address the formidable challenge of insecticide resistance, we introduce phage therapy into pest control, enabling precise targeting and efficient lysis of symbionts that mediate resistance. We employ zein to synchronously encapsulate phages and insecticides, constructing a nano-insecticide. This nano-insecticide ensures stability, exhibits robust performance by protecting phages against temperatures up to 60°C, and enhances their survival under UV irradiation by 83-fold. It intelligently responds to the pest gut enzymes for precise and controlled release, improving FAW control by 17% and overcoming resistance. Additionally, pesticide residue is reduced by 82.4%, with minimal impact on soil and maize microbial communities, preserving seedling growth. This modular, eco-friendly framework offers a sustainable solution for resistant pests, addressing the escalating challenge of resistant pests and paving the way for advancements in sustainable agriculture.

In this study, the crude extract of natural Loropetalum chinense (LoE) was prepared using a simple ethanol leaching approach. Preliminary evaluations of the safening effect of LoE in both agar and soil media demonstrated its ability to protect rice seedlings from damage induced by the herbicide pretilachlor (Pre). Specifically, treatment with LoE at 50 mg/L resulted in a 40.35% increase in root length and a 25.11% increase in plant height. In contrast, treatment at 100 mg/L led to a 36.85% increase in fresh weight, demonstrating effectiveness comparable to that of the commercial safener fenclorim (Fen). Moreover, compared to rice seedlings treated with Pre alone, LoE significantly increased the levels of glutathione (GSH) and enhanced the activities of several important enzymes: glutathione S-transferase (GST), superoxide dismutase (SOD), and catalase (CAT). The mechanism of action for LoE appears to involve enhancing GST activity to accelerate the metabolism of Pre and improving herbicide tolerance by activating antioxidant enzymes. Overall, LoE shows promise as a potential eco-friendly, plant-derived herbicide safener candidate for pretilachlor. For practical commercial application, further efforts should focus on (i) clarifying the phytochemical profile of LoE extracts, and (ii) conducting in-depth assessments of LoE’s mechanisms of action, including studies on degradation kinetics and metabolite formation.

Metal ions are potent antibacterial agents, but suffer from uncontrolled ion release and toxicity. Here, we present Janus liquid metal nanorobots (J-LMNRs) with microenvironment-responsive ion release for precise antibacterial therapy. The J-LMNRs feature a gallium-based liquid metal (Ga-LM) core encapsulated in a Janus platinum (Pt)-polymer shell. The polymer shell modulates ion release thresholds from Ga-LM nanodroplet core, preventing premature activation in healthy tissues, while the asymmetric Pt in the shell amplifies subtle bacterial signals, such as acidic pH (~6.2) and trace hydrogen peroxide levels (~150 μM), into reactive oxide species (ROS) to trigger Ga 3+ ion release. This design enables autonomous chemotaxis towards infection sites and achieves 95% Staphylococcus aureus eradication within 12 h. By coupling signal amplification with adaptive chemical responsiveness, J-LMNRs minimize off-target toxicity and offer a paradigm shift for intelligent antibacterial systems.

The development of highly efficient nanozymes faces challenges of insufficient catalytic activity and low atom utilization. Atomically dispersed metal nanozymes have received widespread attention due to their high atomic utilization efficiency and exceptional catalytic activity. Bimetallic catalysts demonstrated enhanced catalytic performance owing to synergistic geometric and electronic effects arising from heterometallic interactions. Herein, we report an atomically dispersed palladium-iron bimetallic cluster nanozyme, in which fully exposed Pd clusters bonded to adjacent Fe atomic clusters are anchored onto defect-rich nanodiamond-graphene supports (PdFe/ND@G). The Pd-Fe interfacial sites fabricated in atomically dispersed bimetallic clusters deliver abundant oxygen activation sites for high-efficiency catalytic reactions and exhibit enhanced oxidase-like catalytic activity, demonstrating superior enzymatic activity and antibacterial performance compared to monometallic Pd and Fe clusters, while surpassing those of previously reported nanozymes. DFT calculations reveal that, compared to monometallic Pd clusters, atomically dispersed Pd-Fe clusters synergistically catalyze O 2 cleavage into OO* intermediates via Pd-Fe interfacial sites while exhibiting lower energy barriers, which is the critical factor for their enhanced enzyme-like activity. This study provides novel insights into constructing highly efficient atomically dispersed bimetallic cluster nanozymes.
