Controllable growth of hydrogel coatings on diverse substrates is highly desirable yet remains challenging due to the lack of universal and straightforward fabrication strategies. Herein, we present a visible-light-activated, surface-catalyzed radical polymerization approach that enables the controllable in situ construction of hydrogel coatings on a broad spectrum of materials. The process initiates with the deposition of a P(DMA-co-MEA)@g-C3N4 adhesive primer layer, which not only establishes robust interfacial anchoring to the substrate but also functions as a photocatalytic initiator under visible-light irradiation. This interfacial activation drives spatially confined polymerization, yielding uniform hydrogel coatings with precisely tunable thickness. The method demonstrates extensive substrate compatibility─including metals, polymers, and inorganic materials─and readily affords programmable surface functionalities through interfacial chemical design to impart antifouling, lubricating, or biocompatible properties. Owing to its universality, strong interfacial adhesion, and operational simplicity, this strategy provides a versatile platform for the functional tailoring of irregular and three-dimensional surfaces and holds substantial potential for applications in surface/interface engineering and biorelated technologies.

Circularly polarized luminescence (CPL) materials are highly sought after for their unique chiroptical properties, but their rational design remains challenging. To address this, a machine learning (ML) platform that intelligently screens deep eutectic solvents (DES) for crafting G-quartet-based gels with tailored CPL is established. An ML classifier trained on experimental data predicts CPL activity with 0.916 accuracy. SHapley Additive exPlanations (SHAP) analysis identifies key DES molecular descriptors, guiding the discovery of novel materials that exhibit a record-high luminescence dissymmetry factor (g lum ) of 0.222 for nucleotide-based systems and achieve chirality inversion via DES modulation. The Sure Independence Screening and Sparsifying Operator (SISSO) algorithm further yields interpretable design formulas. Leveraging the distinct polarization of these gels, we demonstrate a fourth-level anti-counterfeiting strategy, decrypting concealed information via Morse and ASCII codes to enhance information security. This ML-driven methodology accelerates the discovery of high-performance CPL materials and opens new design avenues.

Construction of ultrathin CoAl-LDHs/g-C 3 N 4 Type-II heterojunction via an electrostatic self-assembly. • Type-II band alignment suppresses charge recombination and boosts charge separation. • Bifunctional design enables efficient H 2 evolution and pollutant degradation. • In-situ XPS and DFT calculations validate the proposed charge transfer pathway. Constructing efficient and stable heterojunction photocatalysts was crucial for achieving bifunctional applications in antibiotic degradation and photocatalytic hydrogen production. Herein, an ultrathin CoAl-LDHs/g-C 3 N 4 Type-II heterojunction was successfully fabricated via an electrostatic self-assembly strategy, and its performance was systematically evaluated for both ciprofloxacin (CIP) degradation and visible-light-driven hydrogen evolution reaction (HER). The optimal CAC2 sample (CAC2, mass ratio of 1:2) achieved a CIP degradation efficiency of 84.9%, which was 1.9-fold and 3.3-fold higher than those of pristine CoAl-LDHs (CAL) and g-C 3 N 4 (CN), respectively. Meanwhile, it delivered a remarkable hydrogen evolution rate of 1935.67 μmol·g −1 ·h −1 , which was 263.3 and 6.5 times higher than those of pristine CAL and CN, respectively. The significantly improved hydrophilicity of the heterojunction enhanced the interfacial enrichment of CIP. Active species trapping experiments confirmed that h + acted as the dominant reactive species, while ·O 2 - played an auxiliary role. Combining XPS, work function calculations, and in situ XPS under light irradiation, we strongly indicate that electrons spontaneously transfer from CAL to CN in the dark, establishing a built-in electric field (BIEF) oriented from CAL to CN. Upon light excitation, the photogenerated electrons migrate from CN to CAL following the typical Type-II pathway, which together with the BIEF synergistically facilitates spatial charge carrier separation. This study elucidated the structure-activity relationship of the electrostatic self-assembled Type-II heterojunction for bifunctional photocatalysis, offering a new paradigm for designing efficient and robust catalytic materials for environmental and energy applications.

Apurinic/apyrimidinic endonuclease 1 (APE1), a critical enzyme in the base excision repair pathway, is a potential biomarker for numerous cancer types. Traditional APE1 activity detection methods are hindered by complex protocols, expensive labeling requirements, and vulnerability to environmental factors. Herein, we develop a label-free ratiometric fluorescent biosensor (TCHG) that integrates APE1-mediated catalytic hairpin assembly (CHA) amplification with split G-quadruplex/malachite green (MG)–mediated aggregation-induced emission (AIE) signaling for sensitive activity analysis of APE1. Our system operates through APE1’s specific cleavage of apurinic/apyrimidinic (AP) site-containing double-stranded substrates, which releases trigger strands that initiate a CHA cascade. This cascade drives the assembly of split G-quadruplex structures. Upon reconstruction, the complete G-quadruplex binds MG, generating amplified near-infrared fluorescence with AIE characteristics. Simultaneously, Hoechst 33258 (HOE) embedded within double-stranded DNA provides a stable reference signal, enabling self-calibrated ratiometric output that effectively minimizes signal fluctuations from instrumental and environmental variations. The TCHG biosensor demonstrates high selectivity for APE1 with a detection limit of 2.4 × 10 –3 U/mL. Importantly, it maintains reliable analytical performance in complex biological matrices, including fetal bovine serum and various cell lysates, successfully differentiating endogenous APE1 activity between normal and cancer cells. The TCHG system offers a tool for APE1 activity analysis in biological samples, with potential applications in biomedical research. Graphical abstract

With the extensive deployment of nuclear energy, uranium contamination—particularly in the hexavalent form U(VI)—has become an escalating threat to aquatic systems. Photocatalytic reduction has emerged as a green and sustainable strategy for environmental remediation. However, achieving high photocatalytic efficiency and effective solar energy utilization remains a significant challenge. In this study, a series of BaTiO 3 /g-C 3 N 4 (BTO/CN) type-II heterojunction photocatalysts were synthesized through a simple hydrothermal method with rational band alignment. The effect of different BTO/CN ratios on U(VI) removal efficiency was evaluated. Among the tested compositions, BaTiO 3 /g-C 3 N 4 -4 exhibited the highest photocatalytic performance, achieving a U(VI) removal efficiency of 96.2% within 20 min of visible light irradiation—significantly outperforming both individual components and other composite ratios. The optimized heterojunction effectively modulated the electronic band structure, facilitating the rapid separation of photogenerated electron-hole (e − -h + ) pairs. Furthermore, the synergistic effect between the heterojunction interface and the intrinsic ferroelectric properties of BaTiO 3 significantly suppressed charge carrier recombination and extended the visible-light absorption range. This, in turn, substantially enhanced the overall photocatalytic efficiency of the system. The rational design of BaTiO 3 /g-C 3 N 4 heterojunctions offers a promising strategy and a robust experimental basis for the development of high-efficiency photocatalysts of uranium remediation.

To develop novel luminescent materials with optical thermometry and anti-counterfeiting functionalities, this work designed, prepared, and characterized a series of Sc 2 Mo 3 O 12 : Eu 3+ (SMOE) phosphors and SMOE/g-C 3 N 4 composites. Structural and optical analyses reveal that SMOE exhibits two-dimensional negative thermal expansion (NTE) behavior and high resistance to luminescence concentration quenching. Via vapor deposition, g-C 3 N 4 was deposited onto SMOE particles, slightly enhancing their NTE performance. Upon UV excitation, SMOE/g-C 3 N 4 shows dual-emission characteristics featuring blue luminescence from g-C 3 N 4 and red-orange emissions from Eu 3+ , with different dependencies on excitation wavelength. Additionally, the g-C 3 N 4 emission band undergoes spectral narrowing and fast thermal quenching with increasing temperature, in contrast to the relatively stable Eu 3+ emissions. These divergent thermal responses enable five independent thermometric parameters (luminescence intensity ratios, spectral bandwidth, and individual emission intensities) to exhibit linear temperature dependence. A multi-parameter sensing strategy based on a multiple linear regression model yields a maximal relative sensitivity of an exceptional 30%/K, surpassing single-parameter approaches and outperforming most previously reported optical thermometers. Moreover, SMOE/g-C 3 N 4 is proved to be highly suitable for anti-counterfeiting labels, as its luminescence color can be switched by controlling the excitation conditions. Overall, SMOE/g-C 3 N 4 is a highly promising dual-functional material coupled with excellent thermal sensing and anti-counterfeiting capabilities.

The improvement in energy storage performance of graphene/polymer composites has long been restricted by insufficient breakdown strength (Eb) and high dielectric loss, both of which result from conductive losses caused by the aggregation of graphene nanosheets. In this paper, aminopropylisobutyl polyhedral oligomeric silsesquioxane (POSS-NH2) encapsulated graphene oxide (GO) (GO-g-POSS) hybrids were prepared to inhibit the restacking of graphene and block the formation of conductive paths. Furthermore, the design of sandwich-structured films is also an efficient approach to improving the breakdown performance of composite materials. Novel sandwich-structured composite films containing outer layers of BNNS/PVDF films and a middle rGO-g-POSS/PVDF layer were successfully prepared by the layer-by-layer assembly process. The B-0.50-B sandwich-structured composites achieved an optimal discharge energy storage density (Ue) of 9.08 J cm−3 and Eb of 432 MV m−1.

Electrocatalytic dehalogenation provides an efficient and sustainable strategy for cleaving carbon-halogen bonds, yet its practical efficiency is often limited by insufficient catalytic activity alongside inherent mass transfer constraints. To address this challenge, this study focused on both the catalyst and reactor levels. Herein, a non-noble metal catalyst, oxygen vacancy-rich Co 3 O 4 /g-C 3 N 4 (O v -CoCN), was developed and integrated into a flow-through reactor for efficient electrocatalytic reductive dehalogenation, which significantly enhanced mass transfer and reaction kinetics. Using the halogenated antibiotic thiamphenicol (TAP) as the target pollutant, the system demonstrated outstanding degradation efficiency under continuous-flow operation. Under optimal conditions with a catalyst loading of 7.1 mg/cm 2 , pH 5, a flow rate of 2 mL/min, and a current density of 7 mA/cm 2 , nearly complete removal of 10 mg/L TAP was achieved. The introduced oxygen vacancies, engineered to modulate the electronic structure of CoCN, played a critical role in facilitating electron transfer and promoting the generation of the key reactive species, atomic hydrogen (H*). The catalyst exhibited excellent application potential, maintaining high removal efficiency across a broad pH range (3−11) and pollutant concentrations (1–50 mg/L), and showed remarkable stability over a 12-h continuous operation. This work provides new insights into the design of both reactors and catalysts for efficient electrocatalytic dechlorination.

g-C 3 N 5 /BiVO 4 - x heterojunctions with tunable BiVO 4 facet ratios were fabricated. • g-C 3 N 5 /BiVO 4 -F shows best activity via suitable (121)/(040) and (040)/(011) ratios. • H 2 O 2 addition boosts photocatalytic degradation efficiency of ceftriaxone sodium. • In-situ XPS confirms the S-scheme charge transfer in g-C 3 N 5 /BiVO 4 -F heterojunction. S-scheme heterojunctions have garnered significant attention in the photocatalytic degradation of antibiotics due to the efficient charge separation and strong redox capability preservation. However, photocatalytic activity is highly dependent on the exposed crystal facet ratios of the catalyst. A series of g-C 3 N 5 /BiVO 4 (N-CN/BiVO 4 -x) S-scheme heterojunctions were fabricated by tuning the morphology of BiVO 4 into peanut-like (BiVO 4 -P), flake-like (BiVO 4 -F), and decahedral structures (BiVO 4 -B), thereby controlling the ratios of exposed crystal facets. Degradation performance tests revealed the optimal performance of N-CN/BiVO 4 -F. This heterojunction achieved a degradation rate of 71.1% for ceftriaxone sodium (CS). With the introduction of H 2 O 2 , the degradation rate further increased to 85.1%. The results confirmed that the superior performance of N-CN/BiVO 4 -F is closely related to the specific exposure ratios of its (121)/(040) and (040)/(011) crystal facets. Furthermore, in-situ XPS confirmed that the charge transfer follows S-scheme charge transfer mechanism. Photoelectrochemical measurements and radical trapping experiments revealed a possible CS degradation mechanism. This work elucidates how the exposed facets of BiVO 4 regulate the photocatalytic performance of S-scheme heterojunctions. The findings provide a theoretical and practical basis for designing efficient photocatalysis systems. Download: Download high-res image (92KB) Download: Download full-size image

Solar-driven carbon dioxide reduction (CO 2 RR) is a highly promising strategy for closing the carbon cycle and enabling the sustainable production of clean chemicals. However, its practical efficiency remains severely limited by sluggish reaction kinetics and competing reaction pathways. In this study, through rational interfacial engineering to induce a stable built-in electric field, we constructed an S-scheme heterojunction based on CeO 2 (110)/g-C 3 N 4 to achieve coordinated modulation of photocatalytic CO 2 reduction. Under gas-solid-phase reaction conditions without a sacrificial agent, the catalyst delivered a yield of 2.51 μmol·g −1 ·h −1 , representing an 8.05-fold enhancement compared with pristine g-C 3 N 4 . A series of experimental investigations indicate that the internal electric field not only promotes the efficient separation and migration of photogenerated carriers but also strengthens CO 2 adsorption and activation, thereby steering the original CO-forming pathway toward an eight-electron-dominated CH 4 pathway. This work may offer a viable heterojunction design strategy for achieving selective CO 2 RR.

G-triplexes are noncanonical DNA structures formed by three guanine tracts, but their sequence design rules for small-molecule binding remain unclear. In this work, we carried out a systematic sequence screening to optimize G-triplex sequences for improved interaction with methylene blue (MB), and applied the best sequence in an electrochemical biosensor for melamine detection. Over 80 candidate sequences were designed by varying loop nucleotides, 5′-flanking bases, and strand length, and were evaluated by square wave voltammetry. The optimal sequence F9 (5′-ATGGGAGGGTGGG-3′) achieved the highest current suppression (ΔI/I0 ≈ 0.81), outperforming all tested G-triplex and several well-known G-quadruplex sequences. Circular dichroism confirmed that F9 folds into a parallel G-triplex with a melting temperature of 65.1 °C, which increased to 70.0 °C upon MB binding. Electrochemical titration gave a 1:1 binding ratio with an association constant of 9.37 × 105 M–1. Molecular dynamics simulations showed that MB binds to the 5′-face of the G-triplex by π–π stacking, with a computed binding free energy of −151.9 kJ/mol. A hairpin probe (MelaPin) combining the F9 sequence with a poly-T melamine recognition region was then constructed. The resulting biosensor showed a linear response over 1–100 μM melamine with a detection limit of 0.74 μM, and a recovery of 96.0 ± 0.8% in spiked infant formula. This work provides a practical framework for G-triplex sequence design and shows that the G-triplex/MB system can serve as a simple, label-free signal module for electrochemical sensing.

In this study, CuTCPP was loaded onto the surface of g-C 3 N 4 through a simple organic reaction to prepare a series of g-C 3 N 4 -CuTCPP (CNTP) photocatalytic composite materials. The material was characterized using XRD, SEM, EDS, and other methods to analyze its physicochemical properties. The biological safety of materials was evaluated through in vitro cytotoxicity experiments. Using E. coli , S. aureus , P. aeruginosa , B. subtilis , and C. albicans as model microorganisms, the broad-spectrum antibacterial performance of composite materials was tested under visible light to investigate the effects of concentration gradient and light exposure time on sterilization efficiency. The antibacterial mechanism was further revealed through reactive oxygen species fluorescence detection, free radical scavenging experiments, and evaluation of cell membrane damage. In addition, livestock and poultry wastewater was used as actual water samples to verify the practical application potential of the materials. Graphical abstract
