#1 [12.7] Highly Sensitive Detection of Food Contaminants Based on an Efficient Quadrupedal DNA Walker

Abstract This research details the development of a highly efficient quadrupedal DNA walker designed for the detection of food contaminants. A cruciform DNA probe was synthesized through a straightforward methodology. Upon specific recognition between target analytes and aptamer sequences, the quadrupedal DNA walker is activated. This activation...

#2 [12.6] 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...

#3 [12.5] A self-calibrating ratio fluorescence aptamer sensor based on PCN-224 for the highly sensitive detection of alternariol in cereals.

Alternariol (AOH) is an emerging mycotoxin widely found in agricultural products. It has drawn attention due to the potential health risks associated with long-term dietary exposure. Therefore, a ratiometric fluorescent aptamer sensor based on PCN-224 was developed. By combining the intrinsic fluorescence properties of PCN-224 with aptamer recog...

#4 [12.1] 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...

#5 [11.6] Streptavidin-Displaying E. coli Scaffolds Enable Target-Mediated Gold Nanoparticle Assembly for Colorimetric Biosensing

Enhancing the visual detection sensitivity of point-of-care (POC) optical sensors without resorting to complex, multistep chemical or enzymatic signal amplification remains a major challenge in sensor nanotechnology. Here, we present a multifunctional bio-nanostructured hybrid platform that integrates engineered Escherichia coli cellular scaffol...

#6 [11.5] 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...

#7 [11.3] 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...

#8 [11.3] 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...

#9 [11.3] Machine learning-assisted cross-reactive aptamer sensor array: A novel universal platform for rapid quantitative determination of pesticide residue structural analogues

#10 [11.1] 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...
