#1 [25.2] 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 [23.3] 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 [18.6] 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 [14.8] 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 [13.0] Sensitive Detection of Biomarker Using Multifunctional Aptamer-Modified Fluorescent E. coli O157:H7

Abstract Highly sensitive quantification of biomarkers is essential for disease diagnosis, treatment monitoring, and prognosis evaluation. Recently, nanomaterial-based immunosensors have attracted increasing attention due to their high sensitivity. However, the preparation of nanomaterials is often complex, costly, and environmentally unfriendly...

#6 [12.0] Programmable Electrochemical Cefapirin Antibiotic Aptasensor Powered by Highly Conductive Bimetallic NiCu(HITP) MOF and Dendritic DNA Amplifications.

Residues of veterinary antibiotics in animal-derived foods motivate the development of analytical methods that combine high sensitivity with straightforward operation. Cefapirin, a β-lactam used extensively for the treatment of bovine mastitis, may persist in milk and other commodities; therefore, sensitive detection of trace-level cefapirin res...

#7 [11.8] 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...

#8 [11.8] 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...

#9 [11.8] A 3D-printed extraction device based on aptamer-functionalized metal-organic frameworks for ochratoxin A determination in alcoholic beverages.

This work reports the development of a 3D-printed extraction device coated with an aptamer-functionalized metal-organic framework (Apt@MOF) for the selective extraction of ochratoxin A (OTA) from alcoholic beverages. Several MOFs were initially screened under dispersive solid-phase extraction (dSPE) conditions, identifying UiO-66-(COOH)2 as the ...

#10 [11.8] Recent advances of colorimetric sensors based on laccase-mimicking nanozymes.

Natural laccase exhibits poor stability, high cost, strict storage requirements and weak recyclability, which greatly limits its utility in colorimetric sensing and catalytic remediation. Laccase-mimicking nanozymes circumvent these shortcomings. Copper derivatives replicate laccase Cu(I)/Cu(II) redox via tailored coordination, whereas Ag-, Mn-,...
