#1 [23.5] 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 [21.7] 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 [17.1] 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 [13.7] A 3D Multiarm PEG/Aptamer-Engineered Interface with Superior Antifouling and Selectivity for Trace Aflatoxin Profiling.

It is challenging to develop a highly selective and antifouling mass spectrometry (MS) ionization interface for the rapid and sensitive detection of trace analytes in complex matrices, such as aflatoxins (AFs) in Traditional Chinese Medicines (TCMs) and milk. In this study, a bifunctional 8-arm PEG derivative (NH2HCl-8armPEG10K-(MTz)7) was engin...

#5 [13.3] Multi-screening of beta-lactam antibiotics in milk based on Fe(3)O(4)@phage/bacteria system and aggregation induced emission luminogen.

BACKGROUND: For the previous rapid screening methods, antibody, molecularly imprinted polymer, aptamer and receptor are the usually used recognition reagents. It is well known that there are many antibiotic receptors on bacterial surface, so in theory the whole bacterium can be used as recognition reagent for screening of the specific antibiotic...

#6 [13.2] 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...

#7 [12.6] A dual-recognition paper-based sensor integrating a Ru/Co nanoparticle-single-atom catalytic interface for trace bisphenol A monitoring in complex matrices.

Although there has been relatively widespread exposure to bisphenol A (BPA) in the environment and consumer products, the sensitivity and selectivity of the current electrochemical sensors are still inadequate for accurate on-site monitoring of complex samples. To fill this deficiency, we have developed a flexible, single-use paper-based sensor ...

#8 [12.3] 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...

#9 [11.3] 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...

#10 [11.2] 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...
