#1 [13.6] Electrospun nanofiber-based solid-phase extraction coupled with aptamer-mediated FRET assay for detection of aflatoxin M(1) in milk.

BACKGROUND: Aflatoxin M1 (AFM1), a highly toxic hydroxylated metabolite of aflatoxin B1, is a major contaminant of concern in milk and dairy products, posing significant risks to food safety and public health. Since AFM1 contamination is closely associated with feed quality, storage conditions, climatic factors, and farm management, reliable AFM...

#2 [13.1] Machine learning-assisted broad-spectrum aptamer discovery and intelligent detection of neonicotinoid pesticides.

A machine learning-assisted computational strategy was developed for the de novo discovery of broad-spectrum aptamers targeting neonicotinoid pesticides (NEOs). Randomly generated DNA sequences were first classified according to secondary-structure similarity using t-distributed stochastic neighbor embedding (t-SNE) and K-means clustering, provi...

#3 [12.5] 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 [12.3] An interface-regulated colorimetric-electrochemical dual-mode aptasensor for acetamiprid detection.

Matrix-derived electroactive interference remains a major analytical challenge for electrochemical aptasensors in complex food samples. We develop a sequential dual-mode aptasensor based on interface regulation for reliable colorimetric screening and electrochemical quantification of acetamiprid. The aptasensor is constructed on a g‑C₃N₄/AuNP-mo...

#5 [12.3] Water-induced supramolecular self-assembly of porphyrin integrated with multivalent metal-organic framework for enhanced electrochemiluminescence and ultrasensitive aptasensing of 4-fluoromethamphetamine.

Aggregation-caused quenching (ACQ) and poor aqueous solubility severely restrict electrochemiluminescence (ECL) applications of polycyclic aromatic hydrocarbons (PAHs). Herein, a water-induced supramolecular self-assembly strategy is proposed to address these drawbacks. Via a simple reprecipitation route, representative PAH meso-tetrakis(4-carbo...

#6 [12.3] Machine learning-assisted cross-reactive aptamer sensor array: A novel universal platform for rapid quantitative determination of pesticide residue structural analogues

#7 [12.1] 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...

#8 [11.0] 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...

#9 [10.7] Dye displacement-based colorimetric aptasensor for rapid pesticide detection.

Pesticide poisoning incidents occur frequently due to the high toxicity and widespread availability of these chemicals. Achieving rapid and accurate on-site identification of pesticides in complex matrices, independent of bulky laboratory instrumentation, remains a major technical challenge. Therefore, we developed an absorption spectroscopic se...

#10 [10.7] 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...
