#1 [16.2] 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 [13.3] 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...

#3 [13.0] 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...

#4 [12.7] 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...

#5 [12.5] A triple-signal-amplified colorimetric biosensor based on 3D-DNA-walker and hybridization chain reaction for sensitive detection of tetracycline residues.

Tetracycline residues in food matrices remain a concern for food safety, making sensitive detection of tetracycline important for residue monitoring. Herein, we developed a triple-amplification colorimetric biosensor for parent tetracycline (TET) detection by integrating aptamer-based recognition, a three-dimensional DNA walker, hybridization ch...

#6 [11.7] Folic Acid Dual-Mode Detection Platform Based on a Selected Aptamer and DNA Tetrahedron-Assisted Catalytic Hairpin Assembly.

Synthetic folic acid (FA) is widely used in food fortification and nutritional supplementation, and is crucial for maintaining human one-carbon metabolism and physiological homeostasis. However, inaccurate labeling, adulteration, or degradation during food processing and storage may lead to abnormal FA levels, highlighting the need for sensitive...

#7 [11.2] A Portable Colorimetric Device for Rapid Bacterial Detection with Cleavable Functional Nucleic Acid Probes for A Common Bacterial Endoribonuclease

ABSTRACT Rapid bacterial detection, including multiplex formats, is critical for clinical diagnostics, particularly when distinct pathogens cause similar symptoms and complicate differential diagnosis. Here we report a portable gold‐coated filter tip‐based assay (GFTA) for rapid, colorimetric, and two‐plex bacterial detection. Cleavable function...

#8 [11.0] Research on a highly sensitive aptamer sensor for Vibrio alginolyticus based on CRISPR-Cas13a and T7 transcription cascade amplification.

Vibrio alginolyticus is a prevalent aquatic pathogen that poses significant risks to public health. Thus, the development of rapid and highly sensitive detection methods is imperative. In this study, we developed a novel aptasensor leveraging the CRISPR/Cas13a system. By integrating a triple-amplification strategy comprising "aptamer competition...

#9 [11.0] Gold nanoclusters-mediated enzyme cascade-amplified immunoassay for dual-mode sensing of aflatoxins

Aflatoxins still pose severe risks to public health due to their high toxicity and carcinogenicity. Herein, we present a novel dual-mode enzyme cascade-amplified immunoassay (ECAIA) for the ultrasensitive and reliable detection of aflatoxins. In this strategy, a nanobody-alkaline phosphatase fusion protein (VHH2-5-AP) was expressed and served as...

#10 [10.8] Capture‐SELEX of DNA Aptamers for Highly Selective Binding of Folate

Folate (vitamin B9) is an essential micronutrient for human health, particularly during pregnancy. Aptamers have emerged as attractive recognition elements for small-molecule detection, as demonstrated by numerous natural riboswitches. Although an RNA aptamer for folate has been reported, the development of a DNA aptamer is highly desirable for ...
