#1 [27.2] A particle counting biosensor mediated by Clostridium butyricum argonaute for simultaneous detection of aflatoxin B(1) and ochratoxin A.

The co-contamination of aflatoxin B1 (AFB1) and ochratoxin A (OTA) in environmental foods has attracted widespread attention. A particle counting biosensor was developed for the simultaneous detection of AFB1 and OTA, utilizing polystyrene (PS) microspheres with diameters of 4 μm and 6 μm (PS4μm and PS6μm) as signal probes and aptamers as biolog...

#2 [24.3] Dual enzyme-mimicking Ce-UiO-66-NO(2)-driven autocatalytic cascade signal amplification for split-type electrochemical aptasensing of enrofloxacin.

Enrofloxacin (ENR) is extensively applied in veterinary medicine for controlling infectious diseases. Nevertheless, the presence of ENR residues in animal-derived food products poses considerable threats to human health. Therefore, the development of highly sensitive and accurate analytical techniques for ENR monitoring is urgently required. Her...

#3 [13.8] Coordination‐Driven Metal‐Phenolic Network Complexes for Programmable Colorimetric Signal Transduction and Defined Nano‐Bio Interfaces

Self-assembled coordination networks provide opportunities to engineer functional nanostructures with programmable physicochemical properties, yet their optical responses and nano-bio interfacial interactions remain poorly understood. Herein, we employ a coordination-driven self-assembly approach to construct metal-phenolic network complexes (MP...

#4 [13.0] Enhanced Fluorescent Aptasensor Via Tetrahedral DNA Framework-Mediated Multivalent Aptamer Network and High-Quantum-Yield Carbon Quantum Dots.

Fluorescent aptasensors are promising molecular diagnostic platforms due to their high specificity, stability, and rapid response; however, their sensitivity for trace-level detection is often limited by the low recognition efficiency of aptamers and suboptimal photophysical properties of fluorescent reporters. Herein, we report an enhanced fluo...

#5 [13.0] Efficient photoelectrochemical biosensing of ochratoxin A with CdTe quantum dots sensitized Z-scheme CuInS(2)/NiTiO(3) heterojunction.

Ochratoxin A (OTA) is one of the most hazardous mycotoxins commonly found in crops and agricultural environments, necessitating sensitive detection methods. This study presents a photoelectrochemical (PEC) biosensor designed for OTA detection, utilizing a CdTe quantum dots (QDs) sensitized CuInS2/NiTiO3 heterojunction. The CuInS2/NiTiO3 composit...

#6 [11.5] An aptamer-integrated bimetallic MOF nanozyme for dual-mode colorimetric and fluorescence sensing of bisphenol A.

As a representative endocrine-disrupting compound, bisphenol A (BPA) can leach from food packaging materials into food, thereby presenting potential risks to human health. Therefore, the development of rapid, sensitive, and reliable methods for BPA detection is of great importance. In this study, a dual-mode colorimetric/fluorescence aptasensor ...

#7 [11.5] PdIr bimetallic nanozyme engineered metal-organic frameworks integrated dual-mode sensor toward Stx2 detection in food.

Shiga toxin II (Stx2) has attracted extensive attention due to its toxicity and pathogenicity, making the development of sensitive detection methods urgent. This study constructed a dual-mode sensing platform for the sensitive detection of Stx2 in food. Composite material UIO-66@PdIr with peroxidase-like activity and fluorescent properties was s...

#8 [11.4] Plasmonic response of aptamer-functionalized gold nanoparticles via target-induced aggregation for oxytetracycline detection.

The widespread use of oxytetracycline (OTC) in sericulture to control bacterial infections and improve silkworm productivity has raised significant concerns regarding the emergence of antimicrobial resistance and antibiotic residue accumulation in seri-products, highlighting the need for reliable monitoring strategies. In this work, we report a ...

#9 [11.3] Defect-Engineered Fe-B MOFs with Intrinsic Neutral-pH Recognition for Accelerated Dual-Mode Detection of Staphylococcus aureus.

This study addresses the challenge of achieving sensitive and reliable Staphylococcus aureus detection in neutral-pH food matrices, where conventional boronate affinity ligands typically lose their binding efficiency. We developed a dual-mode colorimetric-electrochemical aptasensor by rationally designing a defect-engineered iron-boronic acid me...

#10 [11.0] Bimetallic valence relay catalysis in EuTb/N-doped carbon nanosheets: temporal decoupling of oxygen reduction resolves competitive kinetics for ultrasensitive electrochemiluminescence detection of L-cysteine

Accurate monitoring of thiol-containing biomolecules is crucial for understanding redox balance in biological systems. However, conventional luminol-based electrochemiluminescence (ECL) systems rely on unstable H2O2 or suffer from low dissolved O₂ solubility and sluggish kinetics, leading to insufficient reactive oxygen species (ROS) generation ...
