Abstract&Keyword Cite

Abstract :

Sulfonamides (SAs) is a class of antibiotics that extensively used for treating infectious diseases in livestock industries and aquaculture. Thus, it is urgent need to obtain the bio-receptor, which has excellent cross-reactivity and specificity to SAs, for developing high-throughput methods for the determination of multiple SAs even all commonly-used SAs, to realize the quick screening/detection of total SAs in animal-derived foods. We herein isolated several SAs-specific cross-reactive aptamers by using a library-immobilized SELEX with multi-SAs parallel selection strategy. Two of the isolated aptamers (Sul-01 and Sul-04) can specifically recognize and bind seven SAs respectively with higher binding affinity and no interference of non-sulfonamide antibiotics, and thus can be applied as bio-receptors for developing high-throughput aptasensors for the quick screening/detection of multiple SAs. By using the mixture of Sul-01 and Sul-04 as bio-receptor, a ratiometric fluorescent aptasensor was created for the quick detection of nine SAs including sulfamethoxydiazine (SMD), sulfapyridine (SPD), sulfaquinoxaline (SQ), sulfathiazole (ST), sulfamonomethoxine (SMM), sulfamerazine (SMR), sulfaguanidine (SG), sulfamethazine (SMZ) and sulfadiazine (SD) with a detection limit (LOD) of 0.10-0.50 mu M, or total of above nine SAs with a LOD of 0.20 mu M. The fluorescent aptasensor was successfully applied to detect each or total of SMD, SPD, SQ, ST, SMM, SMR, SG, SMZ and SD in fish samples with a recovery of 83 %-92 % and a relative standard deviation (RSD, n = 5) < 5 %. This study not only provided several promising bio-receptors for the development of diverse high-throughput aptasensors to achieve the quick screening of multiple SAs residues, but also provided a simple, stable and sensitive method for the quick screening of SMD, SPD, SQ, ST, SMM, SMR, SG, SMZ and SD in seafood.

Abstract :

On-site quick detection of acetylcholinesterase (AChE) activity is of great significance for diagnosing nervous diseases, screening drugs, and monitoring poisoning. Herein, we developed a system for sensitively regulating gold nanobipyramid (AuNBP) morphology on a paper-based analytical device (PAD) via an Au+-disproportionation system, and further developed a high-resolution paper-based multicolor sensor (PMS) for both on-site visual detection and laboratory precision quantification of AChE activity using the system as a signal reporter and a dual-enzyme strategy as a receptor. The paper-based Au+ disproportionation-mediated AuNBP morphology system not only has excellent stability, reproducibility, and robust resistibility against reducing substances existing in biological samples but also can effectively suppress the color interference from reagents and greatly improve the sensitivity of regulating AuNBP morphology transformation, making it capable of generating long-term stable and more colorful/clearer color changes corresponding to Au+ concentrations. The developed PMS exhibited eight color changes corresponding to AChE activity within 0.0-1.0 U/L and the color changes could be stably maintained for 30 days, which makes both on-site visual detection and laboratory sensitive quantification possible. The PMS was successfully used to detect AChE activity in serum and erythrocyte samples with a visual detection limit (LOD) of 50 mU/L, a spectrometry LOD of 26 mU/L, and a recovery of 81-102%. The results obtained with the PMS were consistent with those obtained with Ellman's method, verifying its reliability. All of the above features make the PMS a promising assay for the rapid detection of AChE activity in clinical diagnosis. Importantly, the proposed paper-based Au+ disproportionation-mediated AuNBP morphology system can serve as a promising general signal reporter for developing various sensitive multicolor colorimetric sensors for target detection in various fields.

Abstract :

Quinolones, a widely used class of antibiotics, present significant environmental and health concerns if they excessively remain in the environment and in food. Aptamers specific to quinolones can be applied as bioreceptors for the detection of quinolone residues in the environment and food. The quinolone family contains dozens of different individuals that share the same core structure coupled with various substituents at six different positions. The diversity and complexity of the substitution sites make it a challenge to choose a set of representative molecules that encompass all the desired sites and preserve the core molecular framework for the screening of quinolone-specific aptamers via systematic evolution of ligands by exponential enrichment (SELEX). To address this challenge, we introduce a novel parallel-series strategy guided by Liebig's law for isolating quinolone-specific cross-reactive aptamers by using the library-immobilized SELEX method. Through this approach, we successfully identified 5 aptamers (Apt.AQ01-Apt.AQ05) with high binding affinity and excellent specificity to 24 different quinolone individuals. Among them, Apt.AQ03 showcased optimal performance with affinities ranging from 0.14 to 1.07 mu M across the comprehensive set of 24 quinolones, exhibiting excellent specificity against nontarget interferents. The binding performance of Apt.AQ03 was further characterized with microscale thermophoresis, circular dichroism spectra, and an exonuclease digestion assay. By using Apt.AQ03 as a bioreceptor, a fluorescence resonance energy transfer (FRET) aptasensor was developed for the detection of 24 quinolones in milk, achieving a remarkable detection limit of 14.5-21.8 ng/mL. This work not only establishes a robust and effective strategy for selecting cross-reactive aptamers applicable to other small-molecule families but also provides high-quality aptamers for developing various high-throughput and reliable methods for the detection of multiple quinolone residues in food.

Portable paper-based multicolor sensor for sensitive on-site detection of organophosphorus pesticides using a high-efficiency Au+-induced gold nanobipyramids aspect ratio regulation strategy SCIE
期刊论文 | 2024 , 207 | MICROCHEMICAL JOURNAL
Abstract&Keyword Cite

Abstract :

On-site visual detection of organophosphorus pesticides (OPs) is crucial for safeguarding environmental and food safety. This study presents a robust, sensitive, and portable paper-based multicolor sensor (PMS) for the on-site detection of OPs. The PMS involves a novel Au+-induced gold nanobipyramids (AuNBPs) morphology transformation reaction within a paper-based analytical device (PAD) coupled with a bienzymatic hydrolysis system. The Au+-induced reaction sensitively regulates the aspect ratio of AuNBPs through Au+ disproportionation, which decreases the length of AuNBPs and simultaneously increases the width, accompanied by distinct multicolor changes. Upon performing in the PAD incorporating easily-prepared AuNBPs-deposited nylon membranes, a metal heater, and an oscillator, the Au+-induced reaction exhibits excellent reaction sensitivity, efficiency, reproducibility, AuNBPs stability, and color uniformity. In the bienzymatic hydrolysis system, acetylcholinesterase (AChE) and choline oxidase hydrolyze acetylcholine to product H2O2, which consumes tris(2-carboxyethyl)phosphine hydrochloride (TCEP), maintaining free Au+ for the disproportionation in the Au+-induced system, while the presence of OPs inhibits AChE activity, preserving TCEP to chelate Au+ and hindering the disproportionation. Under optimized conditions, the PMS exhibited eight dichlorvos concentration-corresponding color changes with a visual detection limit of 30 mu g/L and a spectrometry detection limit of 8.1 mu g/L. It achieved recoveries of 85.4-101.9 % in river water, drinking water, rice, and Chinese cabbage samples with relative standard deviations (n = 5) < 6 %. Thus, this study offers a portable, sensitive, reliable, and practical on-site detection method for OPs. Additionally, the proposed Au+-induced AuNBPs morphology transformation system within the PAD offers promising alternative strategies for developing other AuNBPs-based colorimetric sensors.

Paper-based multicolor sensor for on-site quantitative detection of organophosphate pesticides based on acetylcholinesterase-mediated paper-based Au3+-etching of gold nanobipyramids and CIELab color space SCIE

Abstract :

On-site quantitative detection of organophosphorus pesticides (OPs) is crucial for safeguarding food and public safety. This study presents a novel acetylcholinesterase (AChE)-mediated paper-based Au(3+)etching of gold nanobipyramids (AuNBPs) system. The system employs a long-term storable AuNBPs-deposited nylon membrane embedded within a portable and temperature-controlled paper-based analytical device. This system, coupled with a colorimeter-based quantitative method, enables the development of a practical paper-based multicolor sensor (PMS) for on-site quantitative detection of three common OPs (paraoxon, dichlorvos, and trichlorfon). In the absence of OPs, AChE hydrolyzes acetylthiocholine to thiocholine, which reduces Au(3+)to A(u+). The presence of OPs inhibits AChE activity, thereby preserving Au3+ to etch AuNBPs on nylon membranes, accompanied by multicolor changes. These color changes can be simply quantified by measuring the a* parameter of the CIELab color space using a portable colorimeter. Under optimal conditions, the PMS displayed eight OPs-corresponding color changes with a minimum detectable concentration of 1.0-10 mu g/L (visual observation) and limits of detection of 0.8-7.2 mu g/L (colorimeter) and 0.2-3.4 mu g/L (UV-vis spectrometry). The PMS successfully determined the OPs in vegetable and rice samples with recoveries of 89.0-109 % and RSDs (n = 5) of <6 %. These results were consistent with those obtained using the HPLC-MS method. The PMS demonstrates excellent portability, AuNBPs stability, detection sensitivity, and reproducibility, making it a promising tool for the on-site quantitative detection of OPs residues in food. Furthermore, the paper-based etching system coupled with the colorimeter-based quantitative method provides a valuable reference to develop practical PMSs for various targets in diverse fields.

Abstract :

The lack of inherent structure -switching functionality and inadequate affinity in aptamers hinders the construction and application of aptasensors. While exonuclease digestion -based strategies have been employed to engineer small -molecule aptamers with the structure -switching functionality and construct dual-exonuclease (exonuclease I and exonuclease III) digestion -based aptasensors, such studies targeting G-quadruplex (G4) aptamers remain scarce. This study focused on the exonuclease digestion and circular dichroism spectroscopy analysis of a G4 quinclorac (QNC) aptamer, Qapt-51, intending to design a functionalized QNC aptamer and a universal signal amplification strategy for constructing folding -based and sensitive dual-exonuclease digestionbased aptasensors, respectively. The exonuclease digestion results demonstrated that QNC-binding Qapt-51 inhibited the dual-exonuclease digestion. Combining the results from the circular dichroism spectroscopy, we further proposed a digestion mechanism for Qapt-51 involving a G4 conformational switch. Inspired by this mechanism, a functionalized Qapt-51 variant (Qapt-45A) was rationally designed to construct a simple and rapid folding -based fluorescence aptasensor. Additionally, we developed an exonuclease III- and phosphorodiamidate morpholino oligomer-assisted fluorescence signal amplification strategy, which can work in the dual-exonuclease digestion system. Leveraging this strategy integrated with the dual-exonuclease digestion of another Qapt-51 variant (AQ), a homogeneous signal -amplified fluorescence aptasensor was constructed to sensitively detect QNC without requiring the functionalized aptamers. These two aptasensors achieved detection limits of 560 ng/ mL and 8.5 ng/mL for QNC. They successfully detected QNC in rice and river water samples with recoveries of 108.6%-87.5%. We hope that the successful development of these two aptasensors can provide valuable insights and references for the broader construction of G4 aptamer-based sensing systems.

Abstract :

Quinclorac is an herbicide widely used in rice production, and its residue in water and soil poses significant threats to aquatic organisms and subsequent crops. We herein isolated a group of aptamers with high binding affinity to quinclorac using library-immobilized SELEX. Notably, one of these aptamers (Apt.Q1) demonstrated excellent specificity and affinity to quinclorac, with dissociation constant (Kd) of 8.7 +/- 2.4 mu M and no interference from structurally similar pesticides. Molecular dynamics simulations identified the G-rich loop in Apt.Q1 as the potential binding domain, and circular dichroism analysis revealed the conformational transition from hairpin to G-triplex structure upon quinclorac interaction. Moreover, a one-step, label-free colorimetric biosensor was developed based on quinclorac-mediated displacement of Cy7 dye and Apt.Q1 for detecting quinclorac within 1 min with a detection limit of 237 nM and RSD < 5%. Assessment of quinclorac residues in soil and river water using the biosensor demonstrated recoveries of 89-92%. The study not only provided a promising bioreceptor for developing various quinclorac biosensors but also provided a cost-effective tool for rapidly screening quinclorac in environment. Specifically, the investigation of the recognition mechanism between Apt. Q1 and quinclorac lays a theoretical foundation for designing more sensitive and reliable sensing platforms for quinclorac detection.
