#1 [33.5] Self-powered photoelectrochemical aptasensor based on CHA-triggered G-quadruplex/hemin cascade for homogeneous detection of ochratoxin A in a separated-coupling electrolysis system.

To address the challenge of electroactive interferences derived from complex food matrices during homogeneous photoelectrochemical (PEC) biosensing, a "separated-coupling" electrolysis platform was rationally engineered for the ultrasensitive detection of ochratoxin A (OTA). Based on the analysis of the conduction band of the α-Fe2O3 photoanode ...

#2 [31.6] A novel triple-mode sensor utilizing trimetallic derived fluorescent carbon dots nanozyme for tetracycline determination.

Tetracycline (TC) is notoriously resistant to degradation in natural environments, which contributes to its prolonged persistence and widespread contamination. Improper or excessive use of TC can lead to multifaceted hazards. In this study, we developed a trimetallic-doped carbon dots (Fe,Cu,Ce-CDs)-based composite that exhibits distinct fluores...

#3 [26.6] A bimetallic metal-organic framework-based aptasensor for dual-mode colorimetric and fluorescent detection of Fumonisin B(1).

Fumonisin B1 (FB1) is a secondary metabolite produced by Fusarium species and is considered one of the most dangerous mycotoxins. It is widely present in maize and other agricultural commodities, posing severe threats to human health and animal husbandry. Consequently, the development of a convenient and rapid detection method is of paramount im...

#4 [22.7] Selection and characterization of biofilm-degrading aptamers against Vibrio anguillarum, Vibrio alginolyticus, and Vibrio harveyi and their target protein interaction analysis.

Vibrio is an important pathogenic bacterium, and its pathogenicity and drug resistance are greatly enhanced by its biofilm-forming ability, posing serious threats to food safety and public health. The present study employed Inhibition-Systematic Evolution of Ligands by Exponential Enrichment (SELEX) technology to independently screen aptamers th...

#5 [13.5] Au-Ag NFs@Pt NCs nanozymes-driven aptasensor for sensitive visual detection of aflatoxin B1 in peanut.

Nanozyme-based aptasensors still face challenges, including low catalytic activity and inverse signal correlation, which hinder their advancement in the field of food safety. To address these issues, this study developed a novel nanozyme-based colorimetric aptasensor for the high-performance detection of AFB1. Initially, a gold-silver alloy nano...

#6 [13.5] Ultra-sensitive acrylamide detection in potato chips extract based on carbon paste electrode modified with liposomes carrying ferrocene-labeled aptamer.

The rapid and sensitive detection of acrylamide in thermally processed food products has attracted significant scientific interest. Herein, we report a novel electrochemical aptasensor that integrates a ferrocene-labeled DNA aptamer within a liposome-based nanostructured interface for enhanced signal transduction. The sensing layer was construct...

#7 [12.9] Construction of two fluorescence aptasensors with RecJ(f) exonuclease-induced signal amplification for detecting aflatoxin B1.

Aflatoxin contamination, especially aflatoxin B1 (AFB1), is a major global health concern. There is an urgent need to develop rapid, highly sensitive and specific sensing platforms. In this study, two fluorescence aptasensors were developed for AFB1 detection. The first used quantum dots (QDs) combined with aptamers as molecular recognition elem...

#8 [12.5] A synergistically enhanced electrochemiluminescent aptasensor based on antenna effect and localized surface plasmon resonance for chloramphenicol assessment.

Chloramphenicol (CAP) is a serious antibiotic residue in milk that poses health risks to consumers, prompting the exploration of exceptionally responsive diagnostic techniques such as electrochemiluminescence (ECL). Lanthanide-based coordination polymers exhibit promising ECL via the intrinsic antenna effect, yet they suffer from low radiative d...

#9 [12.5] An integrated litmus test platform for low-background detection and photothermal inactivation of Salmonella typhimurium via HCR-urease signal amplification.

Herein, we propose a novel "low-background" biosensing platform integrating magnetic separation and hybridization chain reaction (HCR) for signal amplification, enabling ratiometric colorimetric detection and visual observation of S. typhimurium. In the presence of S. typhimurium, specific aptamer recognition triggers the HCR to couple the ureas...

#10 [11.8] Spatially confined programmable DNA hydrogel scaffolds accelerate Cas12a trans-cleavage for digital bioimaging.

Molecule diffusion limits target detection in conventional homogeneous solution, typically resulting in inefficient target-probe collision efficiency, low reaction kinetics, and insufficient signal accumulation. Herein, a dual rolling circle amplification-based DNA hydrogel was constructed to establish a hydrogel confined digital imaging platfor...
