Abstract ：
Combined the electrostatic interaction of the negatively charged gold nanorods (AuNRs) (as acceptor) and Ru(bpy)(3)(2+) (as donor), an electrochemiluminescence resonance energy transfer (ECL-RET) sensor was constructed and applied for the detection of organophosphorus pesticides (OPs). Negatively charged AuNRs were synthesized by modifying AuNRs with polystyrene sulfonate (PSS) firstly, which can bind to Ru(bpy)(3)(2+) through electrostatic interaction so that the luminophore was absorbed by the acceptor, the resonance energy transfer occurred and only low ECL signal had been detected. Thiocholine can be produced by the hydrolysis process of acetylthiocholine (ATCh) with the help of acetylcholinesterase (AChE), which can bond with PSS-modified AuNRs (PSS-AuNRs) through gold-sulfur interaction, this caused the releasing of the adsorbed Ru(bpy)(3)(2+) into the solution and resulting in the restoration of the ECL intensity. However, the activity of AChE was inhibited by OPs, and the recovery process of the ECL signal was thus suppressed as well. In this study, chlorpyrifos was chosen as model target, the results indicated that the correlation between the ECL intensity and the logarithm of chlorpyrifos concentration showed remarkable linearity across 1 ng/mL to 1 mg/mL, achieving a detection limit of 0.51 ng/mL. The proposed system has been utilized for detecting OPs in real samples with satisfied results.

Abstract ：
Acid vapors emitted by chemical industries pose an increasing threat to public health. The development of a costeffective sensor for the on-site and real-time monitoring of environmental acid vapor is of great significance. Aggregation-induced emission (AIE) luminogens overcome the aggregation-caused quenching effect and exhibit intense fluorescence when supported in the solid matrices. Silica isoporous membrane (SIM), characterized by vertically ordered nanochannels, holds great promise as a platform for encapsulating AIE luminogens and enabling gas sensing applications. The SIM containing surfactant micelles was prepared on an ITO electrode to obtain the M-SIM/ITO, and Tetrakis(4-carboxyphenyl)ethylene (TCPE) was employed as the investigated AIE luminogen. Upon application of positive potential, the negatively charged TCPE molecules were driven into the vertically ordered nanochannels, resulting in observable AIE fluorescence. By investigating the electrophoresis conditions such as TCPE charge, nanochannel microenvironment, and driving electric field, the AIE mechanism within the nanochannels was elucidated. The fluorescence of TCPE@M-SIM/ITO exhibited high sensitivity towards acid vapor and displayed reversible changes during the absorption and desorption processes. This behavior can be attributed to the SIM's strong absorption capability towards acid vapor as well as the reversible conversion of acid vapor on TCPE aggregates. This work presented an innovative methodology for studying luminophores within an orderly nanoconfined space, leading to a new perspective on the AIE mechanism.

Abstract ：
Herein, a novel dual-function paper-based biosensor using diffusion wet area as readout has been developed for simple and sensitive detection of hyaluronidase (HAase) and human papillomavirus (HPV) 16 DNA, respectively. The target-regulated-water absorption hydrogel synthesized by hyaluronic acid (HA) and single-stranded DNA (ssDNA) is chosen as an ideal material for diffusion wet area generation on paper. The hydrogel can be degraded through the enzymolysis of HA by HAase or the trans-cleavage of ssDNA by HPV DNA-activated CRISPR/cas12a system. Then the diffusion wet area generated by the broken hydrogel with the free water released from the hydrogel dropped on the glass fiber filter paper can be captured by a smart-phone and calculated by the product of the pixel ratio (pixels of wet area/pixels of glass fiber filter paper) and actual area of the filter paper. The diffusion wet area has good linear relationships with HAase (0-40 U/mL) and HPV 16 DNA (0.1-1000 pM), respectively. The biosensor provides a novel signal readout mode, shows satisfactory sensitivity with the detection limits of 0.15 U/mL for HAase and 66.95 fM for HPV 16 DNA, and has been successfully used for HPV 16 DNA and HAase detection in clinical urine and cervical brush samples, which is promising for early cervical cancer screening and HPV monitoring in HPV patients.

Abstract ：
A simple method for one-step synthesis of aggregated gold nanoparticles (a-AuNPs) using single-layer carbon dots (s-CDs) as the capping agents has been proposed. The obtained a-AuNPs are mainly composed of several spherical AuNPs of 20-25 nm sized, which aggregate to form nanogaps of similar to 1 nm. Furthermore, the obtained aAuNPs produce a strong localized surface plasmon resonance (LSPR) absorption band centered at around 640 nm, which is quite close to the wavelength of the commonly used 633 nm laser in surface enhanced Raman scattering (SERS). Thus, under the irradiation of 633 nm laser, a lot of electromagnetic field "hot spots" are formed at around the nanogaps, and strong SERS activity is achieved. The obtained a-AuNPs are dropped on tinfoil wafers to fabricate SERS substrates, which show the advantages of high sensitivity, fast response, good repeatability and satisfactory stability. On the basis, a sensitive SERS sensor is developed to detect malachite green in aquaculture water, with a low detection limit of 1 x 10(-9) mol/L.

Abstract ：
The current surface-enhanced Raman scattering (SERS) substrates typically feature a single energy level, posing challenges in coordinating electromagnetic enhancement (EM) and chemical enhancement (CM), thereby limiting the sensitive detection of numerous crucial target molecules. In this study, novel aggregated nanorings (a-NRs) hybridizing Ag, Au and AgCl are constructed as SERS substrates. On one hand, the obtained a-NRs exhibit robust localized surface plasmon resonance absorption, whose wavelength can be tuned to match three commonly used laser wavelengths (532, 633 and 785 nm) to gain strong EM effect. On the other hand, these materials possess the Fermi levels of Au nanoparticles and Au/Ag alloy, in addition to the valence band and conduction band of AgCl. The abundant energy levels of the obtained a-NRs facilitate increased charge transfer opportunities for molecules, leading to a strong CM effect. Therefore, the obtained a-NRs show ultra-high SERS sensitivity towards numerous molecules. Moreover, the unique chemical composition makes the obtained a-NRs have good long-term stability in terms of SERS activity. Besides providing high-performance SERS substrates, the valuable experience for coordinating EM and CM to construct highly active SERS substrate demonstrated in this work are expected to significantly advance the application of SERS.

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 ：
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 ：
Vertically-ordered mesoporous silica film (VMSF), with large amount of small pores and abundant negative charges, had been modified on the surface of indium tin oxide electrodes and applied to develop an electrochemiluminescence (ECL) biosensor for acute myeloid leukemia biomarker hsa-miR-10a-5p (chosen as a model target). The small ECL indicator (Ru(phen)32+) can be enriched in the pores through electrostatic adsorption and then diffuse to the electrode surface to produce strong ECL signals. The presence of target can trigger hyper- branched rolling circle amplification (HRCA) and produce a large amount of double-stranded DNA (dsDNA). Ru (phen)32+ can embed into the groove structure of dsDNA and forms negatively charged large-sized complexes, which cannot pass through the narrow pores of VMSF to reach the electrode. This led to a significant decrease of ECL signal of the system. The change of the ECL intensity of the system had a linear relationship with logarithm of target concentration within the range of 1 fM-1 nM. The limit of detection was 1.23 fM. The developed biosensor had been applied to determine the target substance in serum samples with satisfied results without complicated sample pretreatment. The introduction of VMSF endows the biosensor with superior anti- interference capability and simpler operational steps, promising applications in the diagnosis of acute myeloid leukemia and potential extension to the analysis of other target molecules through primer design.
