Abstract ：

T-2 toxin, a hazardous mycotoxin often present in cereals and products based on cereals, poses a substantial risk to humans and animals due to its high toxicity. The development of uncomplicated, quick and highly sensitive methods for detecting T-2 toxin is imperative. In this work, a portable sensing system was constructed using water column height as a readout device in combination with a controlled release system, which allows for an accurate quantitative analysis of T-2 toxin without the need for expensive instrumentation or skilled technicians. Hyaluronic acid (HA) hydrogel was constructed by double cross-linked DNA/aptamer hybrids with polyethyleneimine (PEI) and embedded with platinum nanoparticles (Pt NPs). The aptamer specifically bound to T-2 toxin in its presence, resulting in the disruption of the hydrogel and subsequent release of the Pt NPs. These Pt NPs were later mixed with a solution of H 2 O 2 in a confined reaction flask, leading to the decomposition of H 2 O 2 into O 2 . A glass capillary tube containing a column of red water had been inserted into the cap of the reaction flask, and the low solubility of O 2 led to an increase in pressure within the reaction unit, causing the red water column to rise. There is a good linear correlation between the height of the capillary liquid level and the T-2 toxin concentration in the range of 20 ng/mL to 6 mu g/mL. The system has been successfully used to detect T-2 toxin in samples of barley tea and corn.

Abstract ：

A simple and highly sensitive method for detection of miRNA was constructed by combining the high-efficiency thiolated-mediated strand displacement (TMSD) non-enzymatic amplification and the high -reproducibility electrochemiluminescence/electrochemistry (ECL/EC) ratio sensing technique. The EC signal generated by methylene blue (MB) modified on the electrode was used as the internal reference signal, and Ru(phen)(3)(2+) was embedded in DNA nanoparticles produced by the branched hybridization chain reaction as the ECL probe. The presence of target miRNA facilitated the detachment of MB from electrode surface and the modification of ECL beacon on the electrode, resulting in a decrease of the EC signal and an enhancement of the ECL signal. The method of using the ratio of ECL signal to EC signal reduced potential interference and improved reproducibility and sensitivity of the biosensor. The ratio of ECL/EC signals exhibited linear relationship with miRNA-21 concentration in the range from 10 fmol/L to 500 pmol/L, with a detection limit of 6.5 fmol/L, and the relative standard deviation of the assay was reduced from 8.2 % to 4.1 % when determining 1 pmol/L target miRNA-21 compared to that using single ECL signal. This method was preliminarily applied to the detection of miRNA-21 in complex cell samples.

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 ：

Changes in the charge density on the inner surface of the microchannel can modulate the ion concentration at the tip, thus causing changes in the resistance of the system. In this study, this property is adopted to construct a portable sensor using a multimeter and aflatoxin B1 (AFB1) is used as the model target. Initially, the cDNA/aptamer complex is modified in the microchannel. The inner microchannel surface's charge density is then altered by the recognition of the target, leading to a change in the system's resistance, which can be conveniently monitored using a multimeter. Critical parameters influencing the performance of the system are optimized. Under optimum conditions, the resistance is linearly related to the logarithm of AFB1 concentration in the range of 100 fM-10 nM and the detection limit is 46 fM (S/N = 3). The resistive measurement is separated from the recognition reaction of the target, reducing the matrix interference during the detection process. This sensor boasts high sensitivity and specificity coupled with commendable reproducibility and stability. It is applied to assay the AFB1 content successfully in an actual sample of corn. Moreover, this approach is cost-effective, user-friendly, and highly accurate.

Abstract ：

Lead halide perovskites have garnered attention as promising electrochemiluminescence (ECL) emitters owing to their superior photophysical characteristics. However, their poor water stability severely restricts their application in aqueous media for ECL. In this study, inorganic perovskite CsPbBr3 was assembled in situ in the imine-linked covalent-organic framework (COF-LZU1) as a novel ECL emitter. The expansive surface area and robust hydrophobic architecture of COF-LZU1 not only improved the water stability of CsPbBr3 but also guaranteed its exceptional ECL performance. The novel composite nanoluminescent material was coated onto an indium tin oxide (ITO) electrode via spin-coating and calcination processes to serve as an electrochemiluminescence (ECL) platform. A sensor was developed by combining a DNA hydrogel target-induced release system with a platform using ascorbic acid (AA) as a coreactant and T-2 toxin as the target analyte model. This method achieved a detection limit as low as 3.56 fgmL(-1) and was successfully applied to the analysis of the T-2 toxin content in corn samples. This study offers a novel path for the advancement of perovskite-based ECL emitters and their utilization in aqueous environments within the ECL field.

Abstract ：

A series of novel phosphors, specifically Eu3+-doped and Eu3+/M+ co-doped (M = Li+, Na+, K+) SrLaNaTeO6, were synthesized via a high-temperature solid-state process. The luminous properties and thermal stability of these phosphors were thoroughly investigated. When subjected to the appropriate excitation wavelengths (395 and 465 nm), all phosphors demonstrate a pronounced red light emission, corresponding to the D-5(0)-> F-7(2) transition of Eu3+. The researchers found that the most effective concentration of Eu3+ doping in the Sr1-xLaNaTeO6:xEu(3+) phosphor was discovered to be x = 0.25. It was shown that excessive doping leads to concentration quenching, which can be attributed to the energy transfer interaction between Eu3+ ions. The incorporation of Li+, Na+, and K+ as charge compensation ions in conjunction with Eu3+ in Sr0.75LaNaTeO6:0.25Eu(3+) phosphor leads to a notable enhancement in light intensity. Notably, the phosphor co-doped with Na+ exhibits the highest luminous intensity among the alkali metal charge compensation ions. The near proximity of the ion radius of the charge compensation ion Na+ to that of Sr2+ in the host facilitates the occupation of the Na (+) ion in the Sr2+ lattice location. Sodium ions (Na+) have the ability to counteract the positive defects resulting from the substitution of europium ions (Eu3+) with strontium ions (Sr2+), hence maintaining charge neutrality. Additionally, it should be noted that Sr0.5LaNaTeO6:0.25Eu(3+),0.25Na(+) phosphor exhibits a remarkable quantum yield of 71.26 % and lacks thermal quenching. These characteristics suggest that this particular phosphor holds promising potential for utilization in developing white-light-emitting diodes.

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.
