#1 [19.5] 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 [17.8] 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 [14.8] In situ monitoring of ferroptosis via dual-mode imaging of TFR1 expression using an aptamer-engineered MOF-Ag nanohybrid.

Ferroptosis is closely associated with the cytotoxicity of foodborne contaminants, with Transferrin Receptor 1 (TFR1) serving as a critical biomarker. Consequently, the in situ dynamic monitoring of TFR1 is crucial for unraveling the toxicological mechanisms underlying foodborne toxicity. To address the challenges of interference and insufficien...

#4 [13.5] 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...

#5 [13.0] Aptamer-Based Sensing with Fluorescent Light-Up DNA.

DNA aptamers are widely used in the construction of fluorescent sensors, typically employing labelled fluorophores as signaling indicators. However, this covalent labeling approach suffers from several limitations, including complex and costly chemical modification, incompatibility with long aptamer sequences, and susceptibility to false-positiv...

#6 [13.0] Self-Propagating Rolling Circle Amplification Enabled by a Dual-Function Fluorogenic Primer for Ultrasensitive Detection of Salmonella

Abstract Sensitive detection of foodborne pathogenic bacteria is essential for food safety monitoring and public health protection. Herein, we report a self-propagating hyperbranched rolling circle amplification (SP-HRCA) biosensing strategy enabled by a dual-function fluorogenic primer (DFP) for ultrasensitive detection of Salmonella. In this s...

#7 [11.8] Portable dual-color bipolar electrode electrochemiluminescence biosensor array for simultaneous detection and imaging of marine pathogens.

Rapid and sensitive detection of diverse trace bacteria in seawater faces scientific challenges. This work developed a color-potential-spatial highly-resolved bipolar electrode (BPE) electrochemiluminescence (ECL) array sensor for detection and imaging of Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus). Herein, we introduced Agm...

#8 [11.7] Entropy-Engineered Aptamer Truncation Enables Dual-Mode LRET/SERS Aptasensing for Multiplex Detection of Phalloidin and α-Amanitin in Mushroom Samples.

Phalloidin (PHD) and α-amanitin (α-AMT) are structurally constrained cyclic mushroom toxins whose rigid structures and limited accessible recognition surfaces challenge high-affinity molecular recognition and sensitive multiplex detection. Here, we report an entropy-guided aptamer engineering strategy that removes redundant regions while preserv...

#9 [11.7] 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...

#10 [11.3] 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...
