#1 [13.8] 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...

#2 [13.5] Atomically dispersed ruthenium on magnetic layered double hydroxide nanozyme for a multi-mode aptasensor enabling highly sensitive kanamycin detection.

Kanamycin residues in food pose health risks due to their ototoxicity, nephrotoxicity, and antimicrobial resistance promotion. This work reports a multi-mode aptasensor combining atomically dispersed ruthenium-doped magnetic layered double hydroxide (RuSA/MLDH) with exonuclease I-assisted amplification. RuSA/MLDH exhibits DNA-enhanced peroxidase...

#3 [12.4] Self-reduced anchoring of dispersed silver nanoparticles on Wurster COFs combined with graphene quantum dots: signal amplification for a femtomolar chlorpyrifos dual-recognition electrochemical aptasensor.

Accurate detection of the widely used organophosphorus pesticide chlorpyrifos (CPF) is of great significance for ecological systems and human health. In this study, a dual-recognition electrochemical sensing platform was constructed by assembling graphene quantum dots (GQDs) with highly dispersed Ag nanoparticles (AgNPs) anchored on Wurster-type...

#4 [12.0] 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...

#5 [12.0] 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...

#6 [11.5] Synergistic dual-recognition enabled by single-atom nanozyme and aptamer for ultrasensitive colorimetric detection of glyphosate.

While nanozyme-based inhibition strategies are attractive for on-site detection of pesticides, their sensitivity is primarily hampered by insufficient interactions at the nanozyme-pesticide interface. To address this, we developed a dual-recognition system that integrates a Fe/Cu-N-C single-atom nanozyme (SAzyme) with an aptamer for sensitive de...

#7 [10.8] 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 [10.7] 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 [10.7] 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 [10.5] Aptamer-mediated charge neutralization and aggregation of gold nanorods for fast visual monitoring of di(2-ethylhexyl) phthalate in foods and its release from PET containers.

Di(2-ethylhexyl) phthalate (DEHP) is an emerging endocrine-disrupting contaminant, and its rapid monitoring in food is critically important. We developed an aptamer-induced charge neutralization and aggregation of gold nanorods (AuNRs) strategy for facile detection of DEHP. The negatively charged aptamers were adsorbed onto positively charged Au...
