Abstract ：
A highly efficient and sensitive non-enzymatic glucose sensor fabricated using NiO/NiPc composite nanomaterials was introduced by this study. The sensor employed a unique design by modifying the ITO electrode with the NiO/NiPc heterojunction. This enhancement was achieved by improving charge separation and transfer through the type-II heterojunction formed between NiO and NiPc. The integration of NiO/NiPc composite materials also improved the electrocatalytic activity. This enhancement was attributed to the increased concentration of oxygen vacancies, thereby boosting the overall performance of the sensor. The results of the sensor application demonstrated that under the optimized conditions (pH 4.0, -0.3 V bias), the sensor exhibited remarkable sensitivity and selectivity towards glucose, with a linear relationship between the photocurrent change and glucose concentration. The detection limit was as low as 0.016 nM, and the sensitivity was 4.146 mu A & sdot;mM- 1 & sdot;cm- 2. The sensor demonstrated excellent repeatability, stability, and high recovery rate in real sweat sample testing, highlighting its great potential for practical glucose detection applications.

Abstract ：
The persistence of T-2 toxin in food and feed matrices renders it a pervasive contaminant, impacting both human and animal health. Traditional detection methods suffer from cumbersome instrumentation and intricate procedures, rendering on-site detection of T-2 toxin unfeasible. Therefore, we have constructed a real-time detection method for T-2 toxin detection by employing a target-responsive DNA hydrogel in conjunction with potassium iodide starch test paper. This method integrates both colorimetric and distance-based signal outputs, offering a streamlined and effective approach for the on-site detection of T-2 toxin. The specific binding of the target to the aptamer in the DNA hydrogel results in the collapse of the hydrogels structure, which changes the viscosity of the system and released horseradish peroxidase in the hydrogel wrapped, and then produces blue-purple marks of different lengths on the starch iodide papers to achieve the specific detection of T-2 toxin. Under optimized conditions, the assay exhibits a detection range spanning from 10 ng/mL to 10 mg/mL for the toxin, with a detection limit of 12.83 ng/mL. The proposed method has been successfully applied for the detection of real corn samples with satisfied result. Such colorimetric-distance dual signal detection method offers notable advantages, including straightforward operation, clear signal interpretation, and practical utility. Its implementation enables rapid, on-the-spot detection of T-2 toxin, particularly beneficial in resource-limited regions and less developed countries.

Abstract ：
In this study, we present the innovative design and comprehensive evaluation of a novel point-of-care testing (POCT) methodology for the rapid and accurate detection of T-2 toxin, a potent mycotoxin with significant implications for food safety and human health. The cornerstone of this approach lies in the integration of a copper-based conductive metal-organic framework (Cu3(HHTP)2) with a target-responsive DNA hydrogel system, creating a dual-signal readout mechanism that significantly enhances detection sensitivity and specificity. Specifically, the hydrogel covers the material's surface metal active sites, which become exposed upon target addition due to hydrogel collapse. The released Cu3(HHTP)2 can catalyze the oxidation of 3,3 ',5,5 '-tetrame-thylbenzidine, resulting in a colorimetric and temperature change in the solution. This dual-mode detection strategy enables both qualitative assessment through direct visual inspection of color change and quantitative analysis by monitoring the solution temperature variation post laser irradiation with a thermometer. Under the optimized conditions, the detection system demonstrates a wide range spanning from 5 to 200 ng/mL, with a detection limit of 1.67 ng/mL. This method has been successfully demonstrated through the analysis of real-world samples, yielding encouraging results that underscore its reliability and effectiveness. The proposed dual-signal approach boasts advantages such as straightforward operational procedures, unambiguous signal outputs, and robust practicality, making it an attractive option for mycotoxin detection in resource-constrained settings and developing regions.

Abstract ：
Seafood consumption is the major source of total Hg (tHg) and methyl mercury (MeHg) for humans. Lack of broad-representative bio-accessibility of mercury species makes accurate assessment on health risk of seafood's mercury impossible. Herein, the concentrations and in vitro bio-accessibilities of mercury species in 93 seafood samples with 71 different species were extensively investigated. Results indicated that all shellfish and fish samples, and most seaweed samples contained both Hg2+ and MeHg, while some seaweed samples contained only Hg2+. The concentrations of mercury species varied depending on the differences in species/individuals of seafood and sampling regions. MeHg in seafood can be partly de-methylated into Hg2+ during gastrointestinal digestion, which reduced the toxicity of mercury in seafood. The mean demethylation rate of MeHg varied as follows: seaweeds (similar to 62.1 %) > shellfishes/shrimps (similar to 19.7 %) > fishes (similar to 9.2 %). The mean bio-accessibility of Hg2+ and tHg varied as follows: seaweeds (similar to 97.7 % and similar to 90.1 %) > shellfishes/shrimps (similar to 65.1 % and similar to 67.9 %) approximate to fishes (similar to 65.1 % and similar to 66.7 %), while that of MeHg varied as follows: fishes (similar to 57.7 %) > shellfishes/shrimps (50.8 %) > seaweeds (similar to 11.6 %). The simulated calculation of target hazard quotient (THQ) revealed that the health risk of seafood's mercury may be accurately assessed using tHg, not mercury species, even without considering bio-accessibility. This offers a simple but protective approach for assessing the health risk of seafood's mercury. Results of this study provide the potential broad-representative bio-accessibilities of mercury species existing in various kinds of seafood and novel insights for scientifically assessing the health risk of seafood's mercury and revising the mercury limitation in seafood.

Abstract ：
Filling the microchannel with negatively charged hydrogel can exhibit microsacle ion current rectification (ICR) behavior, which is attributed to the space negative charge and structural asymmetry of hydrogel. In this study, this character had been applied to develop a trypsin sensor for the first time. A hydrogel synthesized with bovine serum albumin (BSA) and glyoxal (BSAG hydrogel) was filled at the tip of microchannel firstly. Subsequently, the BSAG hydrogel-filled microchannel was immersed in a trypsin solution to hydrolyze the BSA within the BSAG hydrogel. This process changes the space charge density and pore size of the BSAG hydrogel-filled microchannel, leading to a change in microscale ICR, which can be used for quantifying trypsin. Then the key parameters affecting the sensing performance such as the concentration of BSA, strength of the electrolyte, pH and reaction time were optimized. The detection range was from 10.0 ng/mL to 100 mu g/mL with a detection limit as low as 2.55 ng/mL (S/N = 3). Due to the distinctive three-dimensional pore structure of the hydrogel and the specificity of trypsin for BSA hydrolysis, the sensor exhibits high sensitivity and specificity, as well as remarkable reproducibility and stability. This sensor has been effectively used to measure trypsin levels in human serum samples.

Abstract ：
The contamination of micro-plastics (MPs)/nano-plastics (NPs) in environment poses a global concern, necessitating a scientific evaluation of their potential risks to ecosystems and organisms. We herein investigated the adsorption kinetics of different mercury species including inorganic mercury (Hg2+), methylmercury (MeHg) and ethylmercury (EtHg) on three different MPs, such as polyethylene MPs (PE MPs), polypropylene MPs (PP MPs) and polystyrene MPs (PS MPs) in micro-polluted water in detail, and further evaluated the individual and combined cytotoxicity of polystyrene NPs (PS NPs)/polypropylene NPs (PP NPs) and different mercury species. The results indicated that EtHg undergoes demethylation partly to form Hg2+ during the adsorption process on PP MPs, and the adsorption kinetics of Hg2+, MeHg and EtHg on three MPs fitted with pseudo-first-order (PFO) model in initial stage and simultaneously fitted with pseudo-second-order (PSO) model during whole adsorption process. This suggested that adsorption of mercury species on three MPs we driven mainly by physical process in initial stage and by chemical process during whole absorption process. In natural micro-polluted water, the equilibrium adsorption capacities (Qe) of Hg2+ on three MPs (156.3–270.3 ng/g) are much higher than that of MeHg (5.562–78.13 ng/g) and EtHg (7.831–70.42 ng/g). Cytotoxicity experiments revealed that PP NPs and PS NPs themselves have little cytotoxicity, but the presence of them can enhance the cytotoxicity of mercury species, showing NPs size-depended and mercury species-depended synergistic toxic effect. The findings of this study provided valuable insights for scientifically evaluating the potential risk of MPs/NPs to ecosystems and organisms. © 2025 Elsevier B.V.

Abstract ：
The electrochemiluminescence (ECL) intensity can be regulated by ionic current passing through the microchannel, which broadened the regulation of the ECL sensors. But in the early reported sensors, the electrostatic repulsion and steric hindrance caused few targets to approach the interface of the microchannel driven by concentration difference, which reduced the detection efficiency and prolonged the detection period. In this study, different accumulation strategies, such as a positive electric field and different polarity electric fields, were designed to accumulate targets in the microchannel. The interaction of azide groups and hydrogen sulfide served as a research model. Hydrogen sulfide can react with the negatively charged azide groups in the microchannel surface to produce positively charged amino groups, decreasing the negative charge density of the microchannel and thus altering the ionic current and ECL intensity. The accumulation of hydrogen sulfide at the microchannel tip can increase the collision probability with azide groups to improve the detection efficiency, and the integration of accumulation and reaction can shorten the detection period to 28 min. The hydrogen sulfide concentration on the microchannel tip accumulated by applying different polarity electric fields was 22.3-fold higher than that accumulated by applying a positive electric field. The selected research model broadened the application range of a microchannel-based ECL sensor and confirmed the universality of the microchannel-based ECL sensor.

Abstract ：
A homogeneous electrochemiluminescence (ECL) sensor for hyaluronidase (HAase) detection was developed by controlling the coating of hyaluronic acid (HA) on the surface of magnetic ECL nanoparticles (NPs). Initially, Fe3O4@Ru@SiO2 NPs with magnetic properties were synthesized and subsequently coated with HA (Fe3O4@Ru@SiO2-HA). The properties of HA, such as its negative charge and viscosity, induced strong electrostatic repulsion and reduced electron transfer efficiency between the Fe3O4@Ru@SiO2-HA NPs and the negatively charged electrodes. Furthermore, this coating hindered the approach of co-reactants to the NPs, resulting in a diminished ECL signal. In the presence of HAase, HA is hydrolyzed, releasing the Fe3O4@Ru@SiO2 NPs. Magnetic separation minimizes background interference and allows the magnetic ECL NPs to diffuse freely in solution, facilitating electron transfer and reactant interaction, thereby leading to detectable signal changes. The sensor exhibited a linear response to HAase concentration ranging from 5.0 to 60 U/mL, with a detection limit of 1.8 U/mL. This method is rapid, straightforward, and effectively leverages the inherent properties of HA, making it suitable for broad applications in the detection of proteins, enzymes, and other biomarkers.

Abstract ：
Halide perovskites have emerged as a highly promising class of photoelectric materials. However, the application of lead-based perovskites has been hindered by their toxicity and relatively weak stability. In this work, a composite material comprising a lead-free perovskite cesium copper iodide (CsCu2I3) nanocrystal and a metal-organic framework (MOF-801) has been synthesized through an in situ growth approach. The resulting composite material, denoted as CsCu2I3/MOF-801, demonstrates outstanding stability and exceptional optoelectronic characteristics. MOF-801 may serve a dual role by acting as a protective barrier between CsCu2I3 nanocrystals and the external environment, as well as promoting the efficient transfer of photogenerated charge carriers, thereby mitigating their recombination. Consequently, CsCu2I3/MOF-801 demonstrates its utility by providing both stability and a notably high initial photocurrent. Leveraging the inherent reactivity between H2S and the composite material, which results in the formation of Cu2S and structural alteration, an exceptionally sensitive photoelectrochemical sensor for H2S detection has been designed. This sensor exhibits a linear detection range spanning from 0.005 to 100 mu M with a remarkable detection limit of 1.67 nM, rendering it highly suitable for precise quantification of H2S in rat brains. This eco-friendly sensor significantly broadens the application horizon of perovskite materials and lays a robust foundation for their future commercialization.
