#1 [24.0] 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 [21.3] 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 [13.5] Development of an ultrasensitive magnetic biosensing platform using SERS and aptamer for the ratio detection of chlorpyrifos in tea.

The rapid and accurate detection of chlorpyrifos (CPF), a widely used pesticide in agricultural products, is crucial for food safety assurance. While traditional methods like HPLC and GC-MS are accurate, they remain costly, slow, and lack portability. Herein, an ultrasensitive magnetic biosensing platform was developed for the ratiometric detect...

#4 [13.2] 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...

#5 [13.2] CRISPR-responsive hybrid MOF assembling assay for rapid electrochemical detection of domoic acid.

Domoic acid (DA), a potent neurotoxin, poses a serious threat to food safety and public health. Traditional detection methods often struggle to balance sensitivity with practical applicability. To address this, we developed an electrochemical biosensor based on a CRISPR-responsive hybrid metal-organic framework (MOF) assembling assay. This platf...

#6 [12.6] Pollen-stigma biomimetic framework: a CuCo(2)O(4) nanozyme-based electrochemical aptasensor for ultrasensitive aflatoxin B1 detection.

Inspired by the highly specific recognition and signal amplification of pollen germination on a stigma, we propose a biomimetic electrochemical sensing strategy for ultrasensitive aflatoxin B1 (AFB1) detection. In this pollen-mimetic system, CuCo2O4 nanoflowers serve as "pollen-mimetic grains", with their bimetallic Cu/Co centers functioning as ...

#7 [12.5] Ultrasensitive aptasensor based on SERS-coupled immunochromatography for rapid detection of fenvalerate in food samples.

In this study, we developed an aptamer-mediated surface-enhanced Raman scattering (SERS)-coupled immunochromatographic assay (ICA) for the quantitative detection of pyrethroids. For this approach, core-shell gold nanoparticles (Au@Au NPs) were used as SERS probes by conjugating with aptamers, and fluorescent Raman reporter molecules (MPBN) were ...

#8 [12.3] 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...

#9 [12.3] 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...

#10 [12.0] A novel dual-mode Fluorescence/Colorimetric Aptasensor Based on NH(2)-MIL-88B(Fe)/CDs-Apt for Kanamycin Detection.

Kanamycin (KANA) is a veterinary drug residue that is highly scrutinized in food safety testing. In this study, a metal-organic framework-based aptamer-nanoenzyme (NH2-MIL-88B(Fe)/CDs-Apt) was introduced for the dual-mode detection of KANA. NH2-MIL-88B(Fe) catalyzes the oxidation of 3,3',5,5'-tetramethylbenzidine (TMB) by H₂O₂ to form blue ox-TM...
