Abstract ：
In this work, an electrochemiluminescence (ECL) biosensor for T-2 toxin detection has been designed by combining the high specificity of a DNA hydrogel system with the convenience and sensitivity of homogeneous ECL detection. Specifically, A hydrogel was engineered through the reaction between the carboxyl group of hyaluronic acid (HA) and the amino groups of both polyethyleneimine (PEI) and DNA-modified strands, resulting in a three-dimensional network that encapsulates glucose oxidase. Glucose oxidase (GOD) is capable of catalyzing the conversion of glucose into hydrogen peroxide (H₂O₂), which is a co-reactant necessary for the chemiluminescent reagent luminol to emit light. Upon the presence of the target analyte T-2 toxin, the aptamer recognizes and binds to it, leading to the dissociation and cleavage of the hydrogel framework. This process results in the leakage of the encapsulated GOD into the supernatant. Subsequently, Adding the collected supernatant to a phosphate-buffered saline (PBS) solution containing glucose and luminol for ECL testing yields a noticeable signal change. This sensor eliminates the need for electrode modification, simplifying the operation. Within a concentration range of 10 fg/mL to 100 ng/mL, the ECL signal intensity exhibits an excellent linear relationship with the logarithm of the target concentration, with a detection limit as low as 0.32 fg/mL. The method also demonstrates excellent reproducibility and stability. The sensor demonstrated precise detection capabilities in actual milk and beer samples, a crucial aspect for research focused on specific targets. © 2024

Abstract ：
Homogeneous electrochemiluminescence (ECL) has gained attention for its simplicity and stability. However, false positives due to solution background interference pose a challenge. To address this, magnetic ECL nanoparticles (Fe3O4@Ru@SiO2 NPs) were synthesized, offering easy modification, magnetic separation, and stable luminescence. These were utilized in an ECL sensor for miRNA-155 (miR-155) detection, with locked DNAzyme and substrate chain (mDNA) modified on their surface. The poor conductivity of long-chain DNA significantly impacts the conductivity and electron transfer capability of Fe3O4@Ru@SiO2 NPs, resulting in weaker ECL signals. Upon target presence, unlocked DNAzyme catalyzes mDNA cleavage, leading to shortened DNA chains and reduced density. In contrast, the presence of short-chain DNA has minimal impact on the conductivity and electron transfer capability of Fe3O4@Ru@SiO2 NPs. Simultaneously, the material surface’s electronegativity decreases, weakening the electrostatic repulsion with the negatively charged electrode, resulting in the system detecting stronger ECL signals. This sensor enables homogeneous ECL detection while mitigating solution background interference through magnetic separation. Within a range of 100 fM to 10 nM, the sensor exhibits a linear relationship between ECL intensity and target concentration, with a 26.91 fM detection limit. It demonstrates high accuracy in clinical sample detection, holding significant potential for clinical diagnostics. Future integration with innovative detection strategies may further enhance sensitivity and specificity in biosensing applications. © 2024 American Chemical Society

Abstract ：
The widespread application of metal-organic frameworks (MOFs) is seriously hindered by their structural instability and it is still very challenging to probe the stability of MOFs during application by current techniques. Here, we report a novel structure-responsive mass spectrometry (SRMS) imaging technique to probe the stability of MOFs. We discovered that intact CuBTC (as a model of MOFs) could generate the characteristic peaks of organic ligands and carbon cluster anions in laser desorption/ionization mass spectrometry, but these peaks were significantly changed when the structure of CuBTC was dissociated, thus enabling a label-free probing of the stability. Furthermore, SRMS can be performed in imaging mode to visualize the degradation kinetics and reveal the spatial heterogeneity of the stability of CuBTC. This technique was successfully applied in different application scenarios (in water, moist air, and CO2) and also validated with different MOFs. It thus provides a versatile new tool for better design and application of environment-sensitive materials. A new structure-responsive mass spectrometry imaging technique reveals the change of stability for metal-organic frameworks.

Abstract ：
A colorimetric and photothermal dual readout biosensor for Flap endonuclease 1 (FEN1) quantification was developed on the basis of target-prevented gold nanoparticles (AuNPs) aggregation. The exposed 5 & PRIME;-flap of double-flap DNA substrate modified on SAMBs was firstly cleaved by FEN1. Large amount of cleaved 5 & PRIME;-flap remained in the supernatant after simple magnetic separation, which can adsorb on the surface of AuNPs and effectively prevent the dispersed AuNPs from aggregation under high ionic concentration, accompanied with the color changing of the system, which can be recognized by nake eyes easily. The absorption intensity at 528 nm shows a good linear relationship with the increasing FEN1 concentration from 5.0 x 10-3 to 3.1 x 10-2 U & mu;L-1 with a LOD of 1.6 x 10-3 U & mu;L-1 (S/N = 3). Given the aggregated AuNPs have higher photothermal effect than that of the dispersed AuNPs, the target-prevented AuNPs aggregation avoids a sharp increase of temperature for the system under the laser radiation. The temperature change is linearly correlated with the FEN1 concentration in the range of 3.1 x 10-3-6.1 x 10-2 U & mu;L-1 with a LOD of 1.1 x 10-3 U & mu;L-1. The whole detection process can be completed within 1 h. The proposed system had been applied to detect FEN1 concentration in serum samples with satisfied results, which can be applied in resource-limited area easily and quickly.

Abstract ：
The chemical enhancement of semiconductor-based surface-enhanced Raman scattering (SERS) substrates is an exciting hot topic. Herein, a simple hydrothermal method is developed to prepare molybdenum disulfide (MoS2), which can be easily exfoliated into monolayer nanosheets (MoS(2)NSs) by sonication, even in the absence of any surfactant. The obtained MoS(2)NSs contain two types of defects, namely, one caused by the incorporation of Mo atoms of high valence states and one caused by the incorporation of S-2(2-). The density of the two types of defects can be easily tuned by controlling the ratio of Na2S and Na2MoO4 in the raw materials. The unique properties and the clear surface make the obtained MoS(2)NSs ideal models to investigate the effect of defects on the SERS activity of MoS2. It is found that the SERS activity of the obtained MoS(2)NSs increases dramatically with the defects caused by Mo atoms of high valence states, while it first increases and then decreases with the increase of defects caused by S-2(2-). On the basis, MoS(2)NSs with high SERS activity and a low detection limit of 5.0 x 10(-9) mol/L toward crystal violet (CV) are obtained. Moreover, the mechanism of defects affecting the SERS activity of MoS(2)NSs is revealed. The defects on one hand provide a large amount of dangling bonds that can combine CV molecules to form MoS2NS-CV complex and on the other hand provide extensive induced local dipoles and enhance the overall SERS spectrum of CV.

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 ：
Hydrogel dressings capable of infection monitoring and precise treatment administration show promise for advanced wound care. Existing methods involve embedd ingorganic dyes or flexible electronics into preformed hydrogels, which raise safety issues and adaptability challenges. In this study, an injectable hydrogel based smart wound dressing is developed by integrating food-derived anthocyanidin as a visual pH probe for infection monitoring and poly(L-lactic acid) microcapsules as ultrasound-responsive delivery systems for antibiotics into a poly(ethylene glycol) hydrogel. This straightforwardly prepared hydrogel dressing maintains its favorable properties for wound repair, including porous morphology and excellent biocompatibility. In vitro experiments demonstrated that the hydrogel enabled visual assessment of pH within the range of 5 similar to 9.Meanwhile, the release of antibiotics could be triggered and controlled by ultrasound. In vivo evaluations using infected wounds and diabetic wounds revealed that the wound dressing effectively detected wound infection by monitoring pH levels and achieved antibacterial effects through ultrasound-triggered drug release. This led to significantly enhanced wound healing, as validated by histological analysis and the measurement of inflammatory cytokine levels. This injectable hydrogel-based smart wound dressing holds great potential for use in clinical settings to inform timely and precise clinical intervention and in community to improve wound care management. The study presents an injectable hydrogel dressing with flexibility to fit irregularly shaped wounds and excellent biocompatibility for visual monitoring of infection and on-demand treatment. It utilizes food-derived anthocyanidin as a pH probe and poly(L-lactic acid) microcapsules for ultrasound-responsive drug delivery. In diabetic wounds, the dressing detects infections through pH monitoring and enhances healing via ultrasound-triggered drug release.image

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.
