Herein, a bacteriophage-modified nanozyme sensing platform was developed for dual-mode detection of Staphylococcus aureus in food samples. A peroxidase-like Fe/Ce metal-organic framework nanozyme was functionalized with bacteriophage SAYZU01 to obtain SAYZU01@Fe/Ce MOF, enabling specific recognition and capture of S. aureus . Tetra-(4-aminophenyl) ethylene (TPE-4A), an aggregation-induced emission-active molecule, was introduced as a dual-functional substrate to generate both colorimetric and fluorescent signals after catalytic oxidation. Compared with conventional TMB, TPE-4A provides complementary colorimetric and fluorescent readouts, allowing cross-checking of the sensing response. The captured bacteria inhibited the catalytic activity of SAYZU01@Fe/Ce MOF, resulting in concentration-dependent signal changes. Under optimized conditions, the platform achieved low detection limits of 1.48 × 10 1 CFU mL −1 for colorimetry and 1.27 × 10 1 CFU mL −1 for fluorometry, with a linear range of 2.43 × 10 1 –2.43 × 10 7 CFU mL −1 . This strategy provides a dual-mode approach for rapid pathogen detection in food safety monitoring. Download: Download high-res image (342KB) Download: Download full-size image

Enhanced photocatalytic degradation of dyes in wastewater remains a major focus in environmental research. Herein, a novel spherical binuclear metallophthalocyanine (Zn 2 Pc 2 (EP) 4 ) featuring a planar conjugated structure was self-assembled onto g-C 3 N 4 via π-π stacking interactions. This self-assembly, achieved through a facile “in situ” hydrothermal method, resulted in the construction of a g-C 3 N 4 /Zn 2 Pc 2 (EP) 4 biomimetic photocatalyst. A strong π-π stacking interaction between Zn 2 Pc 2 (EP) 4 and g-C 3 N 4 is evidenced by the red shift of the Q-band absorption peak and the elevated Zn 2p 3/2 binding energy. Furthermore, the luminescence intensity of g-C 3 N 4 /Zn 2 Pc 2 (EP) 4 decreases to 53% of that of pure g-C 3 N 4 , indicating that the π-π stacking interaction promotes the separation of photogenerated electron–hole pairs. The g-C 3 N 4 /Zn 2 Pc 2 (EP) 4 photocatalysts showed good photocatalytic oxidation activity toward methylene blue. The catalytic efficiency of g-C 3 N 4 /Zn 2 Pc 2 (EP) 4 for methylene blue reaches 85.1% after 3h of treatment at room temperature, which is 1.94 times higher than that of pure g-C 3 N 4 . The measured first-order kinetic rate constant is 0.0086 min −1 , exhibiting a 3.44-fold enhancement relative to that of pure g-C 3 N 4 . Mechanistic investigations indicated that the highly reactive intermediate g-C 3 N 4 (e − )/[Zn 2 Pc 2 (EP) 4 ]⁺– * O 2 significantly promoted the photocatalytic oxidative degradation of methylene blue in wastewater. The self-assembled supramolecular g-C 3 N 4 /Zn 2 Pc 2 (EP) 4 offers great potential for developing high-efficiency and environmentally friendly photocatalysts for dye-containing wastewater.

The excessive reliance on traditional fossil fuels has not only triggered an energy shortage crisis but also caused severe environmental pollution. These pollutants can significant accumulate via the process of bioaccumulation within the food chain, ultimately posing a serious threat to human health. Therefore, the development of efficient and precise water quality monitoring technologies is crucial for the prevention and control of environmental pollution. In this study, a g-C 3 N 4 -FeCoNi layered double hydroxide (LDH) heterostructure material (g-C 3 N 4 -LDH) was successfully synthesized using a one-step hydrothermal method. The formation of an n–n heterojunction between g-C 3 N 4 and LDH facilitates efficient interfacial charge transfer and structural stabilization, which is critical for bifunctional applications. Consequently, the constructed g-C 3 N 4 -LDH sensing platform exhibits good performance in 4-NP detection, with a sensitivity of 0.664 μA·μM −1 ·cm −2 , a linear response range of 5–800 μM, and a low detection limit of 0.67 μM (S/N = 3). Moreover, the platform demonstrates strong resistance to interference and excellent stability. Additionally, g-C 3 N 4 -LDH can completely degrade 4-NP within 10 min, effectively detoxifying the pollutants. This study offers new insights and a solid foundation for the rapid and accurate detection and treatment of water pollutants.

A series of novel N-(pyrazol-4-yl)benzamide derivatives featuring diphenylamine or diphenyl ether scaffolds was synthesized and evaluated for antifungal activities. Remarkably, compound 6i demonstrated potent broad-spectrum efficacy against five fungal species, particularly Sclerotinia sclerotiorum, with a half maximal effective concentration (EC50) value of 0.44 μg/mL, outperforming Boscalid (EC50 = 0.71 μg/mL) and nearing Fluxapyroxad (EC50 = 0.26 μg/mL). Additionally, compound 6i exhibited substantial protective effects against S. sclerotiorum on oilseed rape leaves, Rhizoctonia solani on rice leaves, and Valsa mali on apple fruits at 100 μg/mL. Scanning electron microscopy (SEM) analysis further confirmed that 6i could inflict significant damage to S. sclerotiorum hyphae. Further succinate dehydrogenase (SDH) enzymatic inhibition assays, molecular docking, and molecular dynamics (MD) simulations indicated that compound 6i could potentially act as a succinate dehydrogenase inhibitor (SDHI). These findings suggested that 6i held significant promise as an innovative broad-spectrum SDHI for crop protection, warranting further investigation.

The back contact adhesion is the important factor of the microstructural performance which can determine the optoelectronic properties of the kesterite-based solar cells. Here, we present a rational and effective strategy to significantly enhance the back contact adhesion of Cu 2 (Zn,Cd)Sn(S,Se) 4 (CZCTSSe) absorber layers by insetting the appropriate thickness carbon-doping CZCTS thin films . We chose the oleylamine as the carbon-doping reagent which can generate a small amount of carbon in the annealing process . The suitable thickness carbon-doping CZCTS films can significantly change the crystal growth mechanism of CZCTSSe absorber layers, and eliminate the holes in the back contact. The efficiency of CZCTSSe solar cells fabricated by insetting the appropriate thickness carbon-doping CZCTS films is above 7%, and shows the excellent repeatability and long-term air stability compared with the control devices.

Phenolics from the rhizosphere soil are a key factor that leads to obstacles in the continuous cropping system. While we tested the phenolics in the rhizosphere soil of Lanzhou lily ( Lilium davidii var . unicolor ), a high relative content 4-Vinyl Guaiacol (4-VG) was firstly detected. Therefore, we attempted to explore the role of 4-VG stress in Lanzhou lily physiology and disease, and the potential enhanced effects of pathogenicity in Fusarium oxysporum B4 ( F. oxysporum B4). The effects of different concentrations of 4-VG (0, 0.01, 0.05, 0.1, 0.2, 0.5, 1 mM) on the growth of F. oxysporum B4 and the production of fusaric acid were examined. The result indicated that 4-VG inhibited the growth of F. oxysporum B4 hypha, promoted spore germination, and increased fusaric acid content. Furthermore, transcriptome sequencing of F. oxysporum B4 hypha after stress mediated by 0.5 mM 4-VG was performed to help characterize the response mechanism to 4-VG. Compared with the control group, differentially expressed genes (DEGs) were mainly related to the growth and fusaric acid synthesis of F. oxysporum B4. Except that, the increase of infection area formed after F. oxysporum B4 infected the squama of Lanzhou lily under the high concentration of 4-VG was measured and indicated that 4-VG played a role in the F. oxysporum B4 infection. The exogenous addition of 4-VG significantly inhibited the growth and health of Lanzhou lily. Under the dual stress of F. oxysporum B4 and different concentrations of 4-VG, it significantly enhanced the incidence and disease index of Lanzhou lily. These results suggest the key role of 4-VG from rhizosphere soil in the occurrence of Lanzhou lily Fusarium wilt.

Background Detection of the human epididymis secretory protein 4 (HE4) biomarker plays an important role in the early diagnosis of ovarian cancer. This study aimed to develop a novel localized surface plasmon resonance (LSPR) biosensor for detecting HE4 in blood samples from patients with ovarian cancer.Methods Silver nanoparticles were fabricated using a nanosphere lithography method. The anti-HE4 antibody as a probe, which can distinctly recognize HE4, was assembled onto the nanochip surface using an amine coupling method. Detection was based on the shift in the extinction maximum of the LSPR spectrum before and after the HE4-anti-HE4 antibody reaction. These nanobiosensors were applied to detect HE4 in human serum samples and compare them using an enzyme-linked immunosorbent assay.Results Tests relating to the detection of HE4 demonstrated that the LSPR-based biosensor featured a fast detection speed, good specificity, effective reproducibility, and long-term stability. The linear range for LSPR was between 10 pM and 10,000 pM, with a detection limit of 4 pM. An excellent correlation between LSPR and enzyme-linked immunosorbent assay results was observed in human serum.Conclusion This study is the first clinical diagnostic application of the LSPR biosensor in ovarian cancer. The LSPR biosensor, a rapid, low-cost, label-free and portable screening tool, can serve as a very effective alternative for the clinical serological diagnosis of ovarian cancer.

Biological interaction with extremely low-frequency electromagnetic fields (ELF-EMF) is complex and the 50 and 60 Hz frequencies are among a few ‘window’ frequency ranges reported with a stimulating effect. In the current study, ELF-EMF at frequencies from 40 to 70 Hz were examined for their possible significance in inducing biological effects during chilled storage of grass carp ( Ctenopharyngodon idellus ) at 4 °C for 4 and 6 h. The myofibrillar protein extracted from the grass carp was analyzed and the results indicate significant (p < 0.05) increases in Ca 2+ ATPase activity and pH, and a reduction in the total sulfhydryl content during the treatment of 50 and 60 Hz frequencies for both storage durations, in particular, the treatment of 50 Hz had pronounced effects with higher correlations. Therefore, the 50 Hz might be associated with the ‘window’ effect, enhancing myofibrillar protein quality during chilled storage.

4-Phenyl-2-(2′-pyridyl) quinoline ( L1 ) was synthesized by a three-component reaction of aniline, phenylacetylene and pyridine-2-aldehyde catalyzed by trifluoromethanesulfonic acid (TfOH). Its structure was confirmed by FT-IR, MS, NMR and X-ray single crystal diffraction analysis. L1 was investigated as a probe for the detection of Fe 3+ and Fe 2+ ions, which displayed fluorescence enhancement by Fe 3+ and fluorescence quenching by Fe 2+ . This unique fluorescence switching property of L1 was used to identify Fe 2+ and Fe 3+ with high selectivity and sensitivity. The detection limit of Fe 2+ was 8.772 × 10 −9 mol/L and that of Fe 3+ was 1.912 × 10 −9 mol/L. Mechanism investigation revealed that the fluorescence quenching of probe L1 was caused by ferrous-induced PET process and the fluorescence enhancement was due to the combinational effect of ferric-induced PCT enhancement and PET inhibition. In addition, the cyclic voltammetry curves demonstrated that both the Fe 2+ complexes and the Fe 3+ complexes displayed reversible redox process, indicating that the Fe 2+ and Fe 3+ complexes can be reversibly converted into each other upon electrical stimulation. The reversible “On” and “Off” of the fluorescence emission of iron complexes upon electrochemical stimulation could potentially be used in information recording and erasing.

The contamination of polycyclic aromatic hydrocarbons (PAHs) in edible oil is a health threat. Thus, trace analysis of PAHs is of high necessity. Based on the efficient adsorption of PAHs on Zn 5 metal cluster, a Zn 5 functionalized copolymer monolithic column was rationally designed for pipette tip micro-solid phase extraction (μ-SPE). The modified Zn 5 improved the adsorption selectivity and capacity of the monolith for naphthalene, phenanthrene, fluoranthene and pyrene. Chemical doping and copolymerization stabilized the monolith with a long life. Under optimal extraction conditions, a μ-SPE-high performance liquid chromatography with ultraviolet detector method was established for the detection of 4 PAHs in edible oils. The method yielded detection ranges of 0.15–250 μg L −1 ( R 2 > 0.997), detection limits of 0.050–1.5 μg L −1 , satisfactory recoveries (86.3–101.5 %), and high precisions (RSDs < 7.9 %). The results indicated that the Zn 5 functionalized copolymer monolithic column was an ideal separation medium for the detection of PAHs residues in edible oils.

The suitably large modulation depth of the saturable absorber (SA) is crucial to obtaining short pulse lasers via passive Q-switching or mode-locking techniques. Graphene could theoretically be used as a mid-infrared (mid-IR) SA due to its zero band-gap. However, the low modulation depth of graphene in the mid-IR region limits its applications. In this work, to improve the mid-IR modulation depth of graphene, a strategy of functionalizing graphene with narrow-band gap semiconductors was adopted. Graphene/PbSe (G/PbSe) composite was synthesized by a facile hydrothermal process and the reflective G/PbSe SA was prepared by spin-coating method. The saturation absorption properties were investigated by the open aperture Z-scan technique. The results indicated that the saturation absorption properties of G/PbSe SA were largely enhanced, and the modulation depth was increased from 3.02 % to 5.4 % at ∼ 2.8 μm and from 2.5 % to 6.4 % at ∼ 4 μm compared with pure graphene. Moreover, with the as-prepared reflective G/PbSe SA, passively Q-switched Er:YAP laser operation at ∼ 2.8 µm was realized. At the pump power of 6.78 W, the pulse train with pulse width of 326 ns and repetition rate of 107 kHz was obtained, and the average output power was 498 mW. This study presents a way for preparing graphene-based mid-IR SAs for short pulse mid-IR lasers.

Cu2ZnSn(S,Se)4(CZTSSe) films are considered to be promising materials in the advancement of thin-film solar cells. In such films, the amounts of S and Se control the bandgap. Therefore, it is crucial to control the concentration of S/Se to improve efficiency. In this study, Cu2MnxZn1−xSnS4(CMZTS) films were fabricated using the sol-gel method and treated in a Se environment. The films were post-annealed in a Se atmosphere at various temperature ranges from 300 °C to 550 °C at intervals of 200 °C for 15 min to obtain Cu2MnxZn1−xSn(S,Se)4(CMZTSSe). The elemental properties, surface morphology, and electro-optical properties of the CMZTSSe films were investigated in detail. The bandgap of the CMZTSSe films was adjustable in the scope of 1.11–1.22 eV. The structural propeties and phase purity of the CMZTSSe films were analyzed by X-ray diffraction and Raman analysis. High-quality CMZTSSe films with large grains could be acquired by suitably changing the selenization temperature. Under the optimized selenization conditions, the efficiency of the fabricated CMZTSSe device reached 3.08%.Keywords:Cu2ZnSn(S,Se)4film;Mn-doping;solar cells;properties;selenization temperature
