Plasmonic TiB₂@Ag composite dip-coated fabric enables multifunctional smart textiles. • Hierarchical micro-nano asperities impart superhydrophobicity (WCA > 160°) with broad solar absorption. • Rapid photothermal de-icing at −20 °C within 83 s and prolonged freezing delay (∼612 s). • Surface temperature reaches ∼79 °C under 1 sun with ∼72% de-icing efficiency. • Durable, breathable fabric exhibits ≥90% bacterial anti-adhesion with good biocompatibility. Developing ice-resistant, multifunctional fabrics for cold, humid environments remains challenging, particularly in achieving high photothermal efficiency, superhydrophobicity, bacterial anti-adhesion, and mechanical durability without compromising breathability and flexibility. Herein, we report a titanium diboride @ silver (TiB 2 @Ag) composite coating deposited on a nonwoven fabric via a simple dip-coating approach for photothermally driven anti-icing and de-icing performances at low temperatures. The resulting coating surface exhibits hierarchical micro-nanostructured asperities, formed by TiB 2 nanosheets decorated with Ag nanoparticles within a hydrophobic polymer matrix, imparting an excellent anti-wetting surface (water contact angle >160°). The incorporation of plasmonic Ag nanoparticles, combined with strong broadband solar absorption (>90% across 300–2500 nm), synergistically enhances the photothermal conversion performance. Therefore, the functional fabrics show a substantial freezing delay (∼612 s) and rapid de-icing at −20 °C within 83.2 s, achieving a de-icing efficiency of 72%. Under 1 sun irradiation, the surface temperature rises to ∼79 °C within 600 s. The coating also demonstrates excellent bacterial anti-adhesion ability (≥ 90% reduction against E. coli and S. aureus ) with minimal cytotoxicity (>99% cell viability). Importantly, the coated fabrics retain superhydrophobicity (>155°) after repeated sandpaper abrasion and washing cycles, indicating strong coating durability. This fabric exhibits appreciable mechanical resilience (32 MPa at 20% strain, stable after 300 bending cycles) and chemical stability while maintaining flexibility and air permeability for long-term durability. This work provides an effective strategy for designing durable multifunctional textiles with enhanced photothermal anti-icing/de-icing performance for operation in cold environments.

Antibiotics are widely used in the treatment of various diseases in humans and animals, and the detection of metabolic residual antibiotics has become an important research task. Flexible surface-enhanced Raman scattering (SERS) substrates are in great demand for sensitivity and specificity detection of antibiotics. Herein, we constructed a surface-enhanced Raman scattering-molecular imprinting polymer sensor (SERS-MIP) consisting of polyvinyl chloride (PVC) membrane loaded with silver nanoparticles and molecular imprinting layer. The surface of PVC was aminated by nucleophilic substitution reaction as a carrier for the formation of silver nanoparticle. The molecular imprinting method of atom transfer-electron transfer radical polymerization was used to realize the controlled growth of polymer for constructing SERS-MIP sensor, and its detection capability for ciprofloxacin reached 10 −9 M. Simultaneously, the stability, uniformity, reusability, and selectivity of the sensor all showed good performance. The characteristic peaks of ciprofloxacin were still visible in the mixed solution with other interferents. The results indicated that SERS-MIP sensor could realize sensitivity and specificity detection in complex environment.

The efficiency of solar-driven water splitting has long been constrained by the poor utilization of the full-spectrum solar energy by semiconductors. This study leverages the localized photothermal effect of polydopamine (PDA)-mediated plasmonic Ag nanoparticles (NPs) to activate small-polaron hopping conduction in fluorinated BiVO 4 . This activation enhances light absorption and photoelectrochemical (PEC) performance. Experimental evidence indicates that fluorination optimizes both bulk properties and surface wettability. Concurrently, the PDA acts as a multifunctional interfacial layer, ensuring robust adhesion of Ag NPs and serving as an effective hole-transport medium. The synergistic photothermal effect of the intrinsic broadband absorption from PDA and the localized surface plasmon resonance (LSPR) from Ag NPs endows the photoanode with a photocurrent density of 4.96 mA cm −2 at 1.23 V RHE , photo-stability exceeding 10 h, and enhanced light-harvesting capability. Further mechanistic studies unveil that fluorination induces the elongation of local chemical bonds, facilitating reducing the reaction energy barrier. Notably, the loading of PDA@Ag photothermal layer introduces valence band tail states, which effectively narrow the bandgap and accelerate hole transfer. This work offers a novel paradigm for pioneering utilization of photothermal materials to convert thermal energy dissipation into a valuable resource for enhancing PEC performance.

Preparing a hollow Ag-Cu 7 S 4 with lattice defect, improving Seebeck coefficient and thermoelectric effect. • Ag 3d band hybridization narrows bandgap, promotes electron-hole separation and thermoelectric-catalytic ROS generation. • Scaffold enables efficient photothermal conversion and synergistic thermoelectric output under 808 nm NIR-I irradiation. • Thermoelectric boost osteogenesis: 2.1±0.3-fold upregulation of ALP/ARS and 55±2% increase in osteogenic gene and protein. • ROS cascade photothermal disrupt biofilm and GSH, achieving 92±2% ( S. aureus ) and 94.2±2.1% ( E. coli ) antibacterial rates. Cuprous sulfide (Cu 7 S 4 ) shows great potential for thermoelectric treatment of infectious bone defects due to its favorable carrier mobility and thermal conductivity. Nevertheless, its applicability remains constrained by suboptimal carrier concentration, rapid electron-hole recombination, and poor near-infrared (NIR) absorption. Herein, silver ions (Ag + ) were incorporated into Cu 7 S 4 via cation exchange to form hollow Ag-Cu 7 S 4 nanoparticles, and subsequently embedded into polycaprolactone (PCL) to prepare PCL/Ag-Cu 7 S 4 scaffolds. Specifically, Ag utilizes its similar atomic radius to partially substitute for Cu, introducing lattice defects to enhance phonon scattering, further reducing lattice thermal conductivity, thereby enhancing thermoelectric therapy (TET). Meanwhile, hybridization of Ag 3d energy levels with the Cu 7 S 4 band structure optimizes the Fermi level, narrowing the bandgap, thus boosting electron-hole pairs generation and enhancing the thermoelectric catalytic generation of ROS. The scaffolds exhibit excellent NIR absorption and photothermal effect (PTT). The enhanced phonon scattering and conductivity significantly optimize the thermoelectric figure of merit. TET utilized electrical stimulation to promote osteogenic differentiation, upregulating Alkaline phosphatase and Alizarin red by 2.1 ± 0.3-fold and increasing osteogenesis-related mRNA and protein by 55 ± 2%. The narrowed bandgap boosts thermoelectric catalytic ROS generation, ROS synergistically with PTT destroyed the defense systems, achieving antibacterial rates of 92 ± 2% ( S. aureus ) and 94.2 ± 2.1% ( E. coli ).

Surface-enhanced Raman scattering (SERS) faces limitations in its spatial detection range (the “SERS skin depth”) and a trade-off between performance and fabrication simplicity. Here, we propose an opal photonic crystal (OPC)-guided spatial-range SERS detection strategy. This approach synergistically integrates the electromagnetic enhancement of plasmonic nanostructures with the wide-range localized field regulation capability of an OPC to construct a novel hybrid substrate (OPC@Ag NL). The substrate is fabricated by depositing an adjustable silver nanolayer (Ag NL) onto a water-stable, self-assembled OPC template with a tunable PBG. This design synergizes plasmonic enhancement with the OPC's ability to modulate excitation laser, generating an expanded localized field that suppresses electric field decay. Consequently, significant SERS enhancement is maintained up to 300 nm from the surface, enabling 3D Raman imaging of macrophages. The substrate demonstrates high sensitivity (detection limit: 10 − 1 1 m for 4-MBA, EF: 1.7 × 10 7 ) and uniformity (RSD < 5.8%), achieving bacterial detection limits of 10 CFU/mL (labeled) and 10 2 CFU/mL (label-free). This work marks a paradigm shift from hotspot engineering to macroscopic field modulation for overcoming SERS spatial constraints.

To synthesize hybrid nanostructures, precise structural control holds promise to modulate their physicochemical properties. Interestingly, due to the close physico-chemical nature and Galvanic Replacement (GR) between Au ions and Ag, the fabrication of Ag-Au Janus-like structures by growing Au on Ag free of GR is challenging. In this work, in the growth of Au on AgNR seeds, through employing the Na₃Au(SO₃)₂ complex as precursor to inhibit GR and the MBIA ligand as surface energy tuning agent to induce anisotropic growth, the GR-free growth of Au-Island on AgNR was successfully achieved. More interestingly, GR-free site-specific growth of Au-Islands on the entire surface, both tips, and single tip of AgNRs was also realized by varying the concentration of MBIA or the amount of AA reductant, demonstrating the excellent feasibility in synthetic control. These AgNR–Au Janus-like structures exhibit tunable localized surface plasmon resonance (LSPR) across the UV–Vis-NIR range and strong surface-enhanced Raman scattering (SERS) signals, making them promising candidates for LSPR- and SERS-based applications. Our synergistic ligand-mediated structure control strategy can be extended to other bimetallic systems, thus enabling the construction of sophisticated heterostructures with enhanced or new properties for various applications.

Bamboo is a naturally-optimized composite material, but it is prone to deformation, cracking, mildew, and decay. The application of coatings with both mildew and decay resistance can provide long-term protection for bamboo, but bamboo lacks transverse cells and contains few fiber cell cavities and pits, leading to poor coating adhesion. This study subjected Phyllostachys edulis ( P. edulis ) and Neosinocalamus affinis ( N. affinis ) substrates to hygrothermal pretreatment to enhance the adhesion of coatings applied to them. A novel nano-Ag/SiO 2 -modified water-based coating with excellent dispersibility and thermal stability was applied to the surface of the pretreated bamboo strip substrates. The adhesion of the coating reached the highest level (Grade 0, no coating detachment), and its initial and maximum peel forces increased by 53.8% and 41.1% after hygrothermal pretreatment, respectively. Upon increasing the nano-Ag/SiO₂ content, the thickness, adhesion, hardness, scratch resistance, resistance to heating-cooling cycles, and mildew/decay resistance of the water-based coating improved. After the mildew resistance tests, the infection level of the samples decreased from Grade 3 (1/2–3/4 of the surface) to Grade 0 (No visible hyphae), while the discoloration level decreased from Grade 4 (severe surface and internal discoloration) to Grade 1 (minor surface discoloration) after soil burial tests. The weight loss rate, gloss reduction, and color difference of the surface also decreased after both tests. The results showed that the water-based coating modified with 2 wt% nano-Ag/SiO 2 exhibited the best dispersion uniformity, abrasion resistance, and minimal color difference, providing the best decorative and protective performance for the bamboo. The coating extended the service life of bamboo and enhanced its applicability in high-humidity indoor environments and harsh outdoor conditions.

Integrating β-CD-AgNPs and AuNSs arrays enables rapid, quantitative SERS sensing of antibiotic residues. • The system detects AMP, CIP, ENR, NFX individually and in mixtures with high sensitivity. • The combined substrate enabled accurate, applicable antibiotic detection in real waters. β-Cyclodextrin-functionalized Ag nanoparticles (β-CD-AgNPs) were synthesized via a one-step method and integrated with ordered Au nanoshells (AuNSs) arrays to construct a highly sensitive surface-enhanced Raman scattering (SERS) sensor for antibiotic detection. The specific dimensions of the β-CD-AgNPs enable selective binding, drawing antibiotic molecules into close proximity with the AgNPs surface. This proximity generates plasmonic hot spots, significantly amplifying the Raman signals. In this design, the β-CD-AgNPs serve a dual role as both the primary SERS substrate and an internal standard. A strong linear relationship was established between the concentration of antibiotics and the intensity ratio of the characteristic antibiotic peak to the β-CD-AgNPs peak. Based on this principle, we achieved sensitive detection of both individual antibiotics and their mixtures, and validated the method through spike-and-recovery experiments in environmental water samples. The calibration plots were established by linearly fitting the intensity ratio (antibiotic characteristic peak/internal standard peak) against the concentration of Ampicillin (AMP), Ciprofloxacin (CIP), Enrofloxacin (ENR), and Norfloxacin (NFX) solutions, all exhibiting excellent linearity (R 2 > 0.99), as well as for binary mixtures of CIP and AMP, with R 2 values of 0.9942 and 0.9953, respectively. The limits of detection (LODs) for these antibiotics ranged from 0.0827 to 0.3365 μmol·L −1 , and the limits of quantification (LOQs) ranged from 0.27 to 1.11 μmol·L −1 . The linear working ranges were 0.61–5.00, 0.55–12.00, 0.48–12.00, and 1.11–12.00 μmol·L −1 for AMP, CIP, ENR, and NFX, respectively. In environmental water samples, apparent recovery rates of individual antibiotics ranged from 98.84% (±0.03%) to 100.02% (±0.01%), with relative standard deviations (RSDs) between 1.32% and 4.92%. For CIP and AMP mixtures in similar samples, recoveries ranged from 98.53% (±0.01%) to 111.29% (±0.04%), with RSDs between 1.15% and 5.71%. These results demonstrate that the proposed SERS sensor enables efficient and accurate antibiotic detection, offering a viable approach for the rapid and highly sensitive monitoring of antibiotic contaminants in the environment.

Rapid electrification and renewable-energy infrastructure expansion demand copper materials simultaneously achieving high conductivity and robust structural performance. To address this, the study developed a strategy that couples a solution–solid displacement reaction with electrostatic self-assembly to construct hierarchical MXene/Ag@Cu composite powders, thereby achieving dual molecular-level compositing of Ag and MXene. During sintering, the Ag formed a continuous strip-like Ag phase within the Cu matrix, thereby establishing efficient dual pathways for electron and mechanical conduction, as confirmed by both microstructure characterization and finite element simulation. The first-principles analyses further revealed that Ag acts as an interfacial coupling element, effectively bridging self-lubricating MXene nanosheets with the Cu matrix, thereby enhancing electron transport, load-bearing capacity, and tribological performance. Furthermore, the Ag–MXene architecture was shown to construct a robust physicochemical barrier. Thermophysical measurements indicated its role in managing frictional heat, while first-principles simulations revealed its high energy barrier against O diffusion, collectively mitigating oxidative wear. Benefiting from multiscale synergistic reinforcement, the Cu-matrix composite simultaneously achieved high conductivity (96.3% IACS), excellent strength (354.3 MPa), and an ultralow wear rate (1.72 × 10 − 6 mm 3 N -1 m -1 ). These results demonstrate that the hierarchical Ag–MXene architecture successfully overcomes the conventional conductivity–strength–wear-resistance trade-off, offering a promising strategy for next-generation high-performance copper in advanced energy and industrial applications.

Exploring novel luminophores and co-reactant accelerators to enhance electrochemiluminescence (ECL) performance represents a cutting-edge academic research. In this study, a new of ECL system based on copper nanowires (CuNWs) was proposed, which successfully achieved enhanced ECL performance of CuNWs. Specifically, NH 2 –Ag-coated copper nanowires (NH 2 –Ag@CuNWs) were fabricated as a quasi-three-dimensional luminescent composite that integrated both a luminophore and a co-reactant accelerator, distinguished by a low trigger potential of −0.7 V. The NH 2 –Ag@CuNWs composite lumophore not only protect the excellent luminescent properties of CuNWs, but also leverages NH 2 –Ag as an accelerator for the CuNWs/K 2 S 2 O 8 system, shortening the distance required for redox reaction. The dual catalytic effect of the amino groups and Ag promoted the generation of intermediate free radicals from sulfate anions, accelerating electron transfer kinetics and redox reaction rates, while effectively enhancing and stabilizing the luminescent response. Combining the high affinity and selectivity of molecularly imprinted polymers (MIPs), a molecularly imprinted electrochemiluminescence sensing (MIECLS) platform was further developed for ultra-sensitive detection of alpha-fetoprotein(AFP). Under optimized experimental conditions, the detection range of the MIECLS was 10 fg mL −1 to 100 ng mL −1 , and the limit of detection was 1.10 fg mL −1 . This work not only provides a promising strategy for precise detection of AFP in complex matrices, but also proposes new strategies for improving the performance of CuNWs, expanding its applications.

Styrene is one of the most important volatile organic compounds (VOCs) used extensively in polymer and composite manufacturing, where occupational exposure occurs predominantly through inhalation of its vapor. Although surface-enhanced Raman spectroscpoy (SERS) offers exceptional sensitivity for molecular analysis, its application to vapor-phase detection remains challenging because volatile molecules are difficult to efficiently accumulate at plasmonically active sites. Consequently, conventional styrene vapor analysis generally relies on multistep workflows involving vapor sampling and analyte desorption prior to analysis. Herein, we report a flexible Cellulose/ZIF-8/Ag SERS chip combined with a simple attach-and-capture strategy for direct solvent-free detection of styrene vapor. By attaching the SERS sensing chip to the inner surface of a vial cap, vapor sampling and SERS detection were integrated into a single workflow without additional sample pretreatment. The developed SERS platform achieved a detection limit of 240 mg/m 3 , below current occupational exposure limits for styrene, together with excellent analytical reliability (RSDs of 1.89% within a single chip and 5.29% between independently fabricated chips), good selectivity for styrene, stable performance under high relative humidity, robust SERS activity after repeated mechanical deformation, and outstanding post-sampling signal stability. By separating passive vapor accumulation from subsequent spectroscopic analysis, the attach-and-capture configuration enables the chip to be deployed in advance and retrieved for rapid on-demand SERS readout, offering operational flexibility beyond conventional multistep sampling workflows. These findings establish the proposed attach-and-capture strategy as a practical analytical workflow for integrating vapor sampling and SERS detection into a single solvent-free operation for rapid occupational monitoring of styrene vapor.

A novel surface-enhanced Raman spectroscopy (SERS)-based approach is introduced for the highly sensitive detection of perfluoroalkyl and polyfluoroalkyl substances (PFAS), polytetrafluoroethylene (PTFE), and polystyrene (PS) nanoplastics in serum samples using silver nanowire mesh (AgNWM) as SERS substrates. The surface-enhanced Raman scattering performance of AgNWM substrates was optimized using rhodamine 6G as a probe molecule, achieving a limit of detection (LOD) of 10 −9 M. Serum samples were subjected to pre-treatment steps, including protein removal, sample enrichment, and concentration, enabling quantitative detection of multiple PFAS species at as low as 10 −8 M. PTFE and PS nanoplastics were also successfully identified at a concentration of 100 ng·mL −1 . Furthermore, the AgNWM substrates exhibited significant stability and could be reused up to 10 times for plastic detection without substantial loss of sensitivity. This highly sensitive SERS platform provides an innovative and effective methodology for the detection of PFAS, PTFE, and PS nanoplastics in complex biological matrices, with considerable potential for clinical and environmental analyses.
