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 :

Real time detection of hydrogen sulfide (H2S) in deep brain regions is of great significance. Photoelectrochemical (PEC) biosensors hold promise for real-time monitoring but low sensitivity due to the use of small electrode restrained its application. In this study, a miniaturized sensor that integrates organic photoelectrochemical transistors (OPECTs) with optical fiber (OF) microelectrodes was designed for the first time, which can amplify the small PEC signal into large channel current change. A conductive gold layer and cuprous oxide nanoparticles (Cu2O NPs) were sequentially deposited onto the OF, followed by a Nafion polymer coating to enhance anti-interference capabilities. Cu2O reacts with H2S to generate Cu2S. The resulting Cu2O/Cu2S heterojunction induces changes in the PEC signal and channel current. Compared to a conventional PEC system, the OPECT sensor has higher sensitivity and lower detection limit, enabling monitoring of H2S concentration fluctuations within the rat brain, which demonstrates the approach's capability for highly sensitive in vivo biomarker detection.

Abstract :

The intracellular delivery of protein drugs via nanocarriers offers significant potential for expanding their therapeutic applications. However, the unintended activation of innate immune responses and inflammation triggered by the carriers presents a major challenge, often compromising therapeutic efficacy. Here, we present oligoethylenimine-thioketal (OEI-TK), a reactive oxygen species-responsive cationic polymer with intrinsic anti-inflammatory properties, to overcome this challenge. OEI-TK self-assembles electrostatically with bovine serum albumin (BSA) to form stable nanoparticles (OTB NPs) with excellent encapsulation efficiency. In vitro studies confirmed that OTB NPs retained OEI-TK's antioxidant and anti-inflammatory properties, enhanced biocompatibility, and efficiently delivered BSA into cells. Furthermore, OEI-TK facilitated the intracellular delivery of beta-galactosidase while preserving its enzymatic activity, demonstrating its potential for functional protein transport. These findings highlight OEI-TK as a promising platform with dual benefits of inflammation modulation and intracellular protein delivery, holding potential for the synergistic treatment of inflammation-related diseases.

Abstract&Keyword Cite Version(1)

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&Keyword Cite Version(2)

Abstract :

Multifunctional hydrogels hold significant promise for promoting the healing of infected wounds but often fall short in inhibiting antibiotic-resistant pathogens, and their clinical translation is limited by complex preparation processes and high costs. In this study, a multifunctional hydrogel is developed by combining metal-phenolic networks (MPNs) formed by tannic acid (TA) and gallium ions (Ga3+) with chitosan (CS) through a simple one-step method. The resulting CS-TA-Ga3+ (CTG) hydrogel is cost-effective and exhibits desirable properties, including injectability, self-healing, pH responsiveness, hemostasis, antioxidant, anti-inflammatory, and antibacterial activities. Importantly, the CTG hydrogels are effective against antibiotic-resistant pathogens due to the unique antibacterial mechanism of Ga3+. In vivo studies demonstrate that the CTG hydrogel promotes follicle formation and collagen deposition, accelerating the healing of infected wounds by inhibiting blood loss, suppressing bacterial growth, and modulating the inflammatory microenvironment. These findings highlight the CTG hydrogel's potential as an advanced and translational dressing for enhancing the healing of infected wounds.

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.

Sensitive trypsin sensor based on the regulation of microscale ionic current rectification by the selectivity hydrolysis of hydrogel filled in microchannel SCIE
期刊论文 | 2025 , 285 | TALANTA
Abstract&Keyword Cite Version(2)

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 :

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 :

The control of nanoparticle morphology can effectively change their properties. Adjusting the aggregation state of bovine serum albumin-coated gold nanoclusters (BSA-Au NCs) can regulate the enzyme-mimicking catalytic activity. Hyaluronic acid (HA) induces the aggregation of BSA-Au NCs, leading to the shielding of the catalytic active sites and a decrease in activity; this feature has been utilized to design a multicolor biosensor for hyaluronidase (HAase). The presence of HAase can hydrolyze the glycosidic bonds in HA, causing the aggregated BSA-Au NCs to disperse and express their catalytic activity, which in turn catalyzes the etching of Au nanobipyramids (Au-NBPs) in the presence of 3,3 ',5,5 ' -tetramethylbenzidine (TMB), resulting in a morphological transition from bipyramidal to ellipsoidal and spherical shapes, while the solution displays a variety of colors. Visual recognition of these multicolor changes establishes a relationship between the enzyme activity and color. Based on the controlled aggregation and dispersion of BSA-Au NCs and the etching of Au-NBPs, a simple multicolor HAase biosensor was designed. The proposed biosensor shows a linear response to HAase concentrations in the range of 5-80 U/mL, with clear color changes under optimized conditions. The limit of detection (LOD) of the sensor was determined to be 1.98 U/mL (LOD = 3s/k). This method successfully applies the changing of enzyme-mimicking catalytic activity nanoparticles for colorimetric analysis detection.

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
