#1 [15.6] Hydrovoltaic-photoelectric coupling effect boosted self-powered aptasensor for on-site and ultrasensitive monitoring of enrofloxacin in aquaculture products based on CdS/ZIF-67 heterojunctions.

On-site monitoring of antibiotic residues in aquaculture products is of great significance for providing instant content information to protect food safety and human health. In this work, a novel hydrovoltaic self-powered electrochemical sensor was fabricated for real-time sensitive detection of enrofloxacin (ENR) by integration of photoelectric...

#2 [13.8] Advancing point-of-care diagnostics: Engineering and enhancing sensitivity and specificity in nanoparticle-based lateral flow assays for rapid disease detection.

Lateral flow assay (LFA) is the most widely used point-of-care (PoC) diagnostic tools due to their simplicity, rapid turnaround, portability, and low cost. Despite their extensive adoption in clinical diagnostics, food safety, and environmental monitoring, conventional LFA remain limited by inadequate sensitivity, poor quantification, and restri...

#3 [13.8] Switch-type photoelectrochemical aptasensor for microplastics and nanoplastics detection based on two-dimensional organic-inorganic heterojunction.

Microplastics and nanoplastics (MNPs) as emerging pollutants present substantial risks to both the environment and human health. Developing highly sensitive methods to rapidly identify and detect low concentrations of MNPs in complex systems remains a considerable challenge. Here, an "off-on" switch-type photoelectrochemical (PEC) aptasensor was...

#4 [13.8] Ratiometric fluorescence aptasensor based on hollow mesoporous silica for gentamicin detection.

Gentamicin (GEN) is an aminoglycoside antibiotic widely used in animal husbandry because of its low cost and high therapeutic efficacy; however, its residues in milk pose a potential risk to food safety. In this study, a truncated aptamer (G41) with high affinity toward GEN was obtained through molecular docking and molecular dynamics simulation...

#5 [13.8] Organic electrochemical transistors (OECT) based biosensors for the detection of small molecule metabolites.

Recently, organic electrochemical transistors (OECTs) have emerged as robust platforms for chemical and biological sensing, due to their intrinsic signal amplification, biocompatibility, and low-voltage functionality. OECTs have exhibited tremendous promise for detecting small molecule metabolites (SMMs), which are crucial as biomarkers in medic...

#6 [13.8] A dual-mode sensing strategy for the detection of Malathion based on bimetallic nanozymes coupled with aptamers.

Malathion (MLT) is an organophosphate insecticide with well-defined toxicity to the human body. Both short-term exposure to high doses and long-term exposure to low doses can impair human health. In this study, we developed a novel colorimetric and photothermal method for the detection of MLT using aptamer (Apt)-conjugated FeCu-metal-organic fra...

#7 [13.0] Development of a Core−Shell-Encapsulated Biosensor for On-Site Detection of Trace Chlorpyrifos

Chlorpyrifos, a broad-spectrum organophosphorus pesticide, accumulates persistently in the environment and food chain, posing significant risks to ecosystems and human health. Whole-cell biosensors offer a promising alternative for on-site pesticide detection. However, their practical application is hindered by insufficient sensitivity for trace...

#8 [13.0] Fluorescent covalent organic framework and multivalent aptamer-driven magnetic nanoplatform for sensitive detection of foodborne pathogens.

Analytical platforms capable of rapid detection of foodborne pathogens with high sensitivity and localized specificity are indispensable not only for quality control protocols in the food industry but also broader applications in clinical diagnostics, public health surveillance, and environmental monitoring. Here, we engineered a novel fluoresce...

#9 [12.6] Development of a covalent organic framework/graphene oxide aptasensor for electrochemical penicillin detection.

The rapid and sensitive detection of trace antibiotics in environmental and biological samples is crucial for food safety and public health. This study presents a novel electrochemical aptasensor based on a porous covalent organic frameworks/graphene oxide (namely COF/GO) hybrid material for selectively detecting penicillin (PCL). A specific apt...

#10 [12.3] Selection of Aptamers To Detect Lean Meat Agents: Ractopamine and Clenbuterol.

In this work, a library-immobilization method was used to select DNA aptamers for ractopamine (RAC) and clenbuterol (CLB), two common "lean meat agents". Two RAC-binding aptamers, RAC-1 and RAC-5, exhibit dissociation constants (Kd) of 6.8 and 2.9 μM, respectively, based on isothermal titration calorimetry (ITC). Similar values were also obtaine...
