#1 [14.8] Aptamer-cDNA-driven nanozyme strategy: A recyclable dual-signal immunosensor for amplified detection of aflatoxin B(1) in edible oil.

Aflatoxin B1 (AFB1) poses a serious threat to human health, highlighting theurgent need for sensitive, precise and visual detection methods in daily foods. However,traditional detection methods relying on peroxidase (POD)-mimetic activity are susceptible to external interference, which increases false-positive or false-negative rates and comprom...

#2 [13.5] Photoelectrochemical and colorimetric dual-mode aptasensor for nonylphenol detection in food based on ascorbic acid-sensitive Bi(2)S(3)/Bi(2)O(2)CO(3) heterojunction and multi-enzyme-mimicking Ce-MOF.

A simple and novel photoelectrochemical (PEC)-colorimetric (CL) dual-mode aptasensor was explored for nonylphenol determination using ascorbic acid (AA)-sensitive Bi2S3/Bi2O2CO3Z-Scheme heterojunction and Ce(III/IV)-MOF (R-UiO66-Ce) with dual enzyme-mimetic activity. Firstly, ascorbic acid phosphate was hydrolyzed under R-UiO66-Ce catalysis to g...

#3 [13.3] A Fossilization-Inspired Photoelectrochemical Sensing Platform: DNA-Induced In Situ CaCO3 Crystal Growth Modulates The Photoelectrochemical Response of Gold Electrodes for Ultrasensitive Aflatoxin B1 Detection.

Although photoelectrochemical (PEC) sensing offers low background and high sensitivity, most PEC platforms rely on semiconductor materials and immobilized recognition probes, which complicate electrode fabrication and reduce operational simplicity. Herein, we report a fossilization-inspired photoelectrochemical sensing platform (FIPSP) for ultra...

#4 [12.8] A novel label-free electrochemical aptamer sensor based on base mismatch and strand displacement for detection of kanamycin.

Misuse of kanamycin in animal husbandry has led to serious food safety issues. In this study, a label-free electrochemical aptasensor based on the base mismatch and strand displacement was developed for detection of kanamycin residue in agricultural products. A novel ferrocene-naphthalimide derivative was employed as the electroactive indicator....

#5 [12.0] Label-free and enzyme-free fluorescent biosensor for ultrasensitive detection of tobramycin via cascade signal amplification.

Uncontrolled use of tobramycin (TOB) raises serious health concerns, including nephrotoxicity and ototoxicity, making it imperative to develop simple and sensitive detection methods. This study introduces a novel enzyme-free and label-free fluorescent biosensor based on a cascade signal amplification strategy, integrating an entropy-driven DNA c...

#6 [11.1] A dual signal ratio electrochemical sensor based on DNA tetrahedrons and bimetallic nanocomposites for AFB(1) analysis.

Given the hepatotoxicity and widespread contamination of Aflatoxin B1 (AFB1), developing ultra-sensitive, anti-interference analytical platforms is paramount for public health. Herein, a dual signal ratio electrochemical sensing platform for accurate AFB1 analysis was constructed integrating DNA tetrahedrons (TNDA), a dynamic DNA walker, and nit...

#7 [10.9] Aptamer screening within sample matrices: Toward reliable applications.

Nucleic acid aptamers are short oligonucleotide sequences selected in vitro by Systematic Evolution of Ligands by EXponential enrichment (SELEX). As "chemical antibodies", they recognize diverse targets with high affinity and specificity through structure-dependent interactions and offer multiple attractive features. Although a few natural aptam...

#8 [10.8] A hairpin conformational change-mediated SRH cascade isothermal amplification assisted electrochemical biosensor for Listeria monocytogenes detection.

The rapid and sensitive detection of foodborne pathogens is crucial for safeguarding food safety and public health. In this study, we developed an electrochemical biosensor based on a hairpin conformational change-mediated cascade isothermal amplification strategy for the detection of Listeria monocytogenes in food. The biosensor employs aptamer...

#9 [10.7] ZIF-67-DerivedHollow Nanozyme with Dual QuenchingMechanisms Coupled with DNA Walker as an Aptasensing Platform forSensitive Detection of Acetamiprid

Abstract Acetamiprid (ACE) is a widely used neonicotinoid insecticide with high insecticidal efficacy; however, its residues in food and environmental matrices have raised concerns regarding potential risks to human health. In this work, a DNA walker amplification strategy integrating the dual electrochemiluminescence (ECL) quenching pathways of...

#10 [10.5] A molecularly imprinted electrochemical aptasensor based on graphene and tin dioxide composite with electrodeposited gold nanoparticles for dual recognition of enrofloxacin.

In this work, a molecularly imprinted electrochemical aptamer sensor (MIEAS) for the detection of enrofloxacin (ENR) was developed using SnO2-graphene (SnO2-Gr) and gold nanoparticles (AuNPs) as electrode modification materials. The SnO2-Gr composite material has a large specific surface area and can enhance the conductivity of the sensing platf...
