#1 [24.3] AI-driven Cu/Mn-CeO(2) nanozyme-functionalized paper-based biosensor for quantitative monitoring of alternariol in food.

The lack of rapid, user-friendly methods for alternariol (AOH), a prevalent emerging mycotoxin, presents a considerable analytical challenge. This work introduces an integrated sensing strategy advancing from classical homogeneous liquid-phase detection to a portable AI-enhanced paper-based biosensor. The system employed a Cu/Mn-CeO2 nanozyme as...

#2 [13.8] Synergistic graphene-aptamer coating on a flexible metasurface enables on-apple terahertz sensing of pesticides.

The critical need for rapid, on-site pesticide detection has driven interest in terahertz (THz) sensing. This study presents a flexible THz metasurface functionalized with an aptamer-graphene hybrid layer for specific detection of chlorpyrifos. Graphene enriches target molecules via π-π stacking, while the aptamer ensures precise recognition. Us...

#3 [13.3] Triple-amplification electrochemiluminescence aptasensor integrating single-atom nanozyme catalysis with CRISPR-Cas12a/HCR cascade for zearalenone detection.

Single-atom nanozymes (SANs) are emerging as interfacial catalysts that can modulate surface-confined reactive oxygen species (ROS) generation at the electrode/solution boundary. Herein, an interface-driven electrochemiluminescence (ECL) aptasensor was constructed for the ultrasensitive detection of zearalenone (ZEN), a mycotoxin of significant ...

#4 [13.0] Dual-Functional Ratio Photoelectrochemical Biosensing Platform for Photothermal Simultaneous Sterilization and Lipopolysaccharides-Mediated Detection of Escherichia coli O157:H7.

As biosafety requirements continue to increase, there is a growing interest in foodborne-pathogen detection methods that can be operated safely. In this work, a dual-functional "sterilization-detection" photoelectrochemical (PEC) biosensing platform is developed based on a Fe3O4/copper-benzene-1,3,5-tricarboxylic acid (Cu-BTC), which integrates ...

#5 [12.1] Plasmonic graphene oxide aptasensor empowered for ultra‑sensitive and rapid detection of aflatoxin M1 in dairy product.

Aflatoxins are toxic metabolites and potent carcinogens that pose a threat to both humans and animals even at trace levels. In this study, we developed a robust plasmonic graphene oxide-based aptasensor for rapid and specific detection of Aflatoxin M1(AFM1) in dairy products. The Graphene Oxide-Chitosan (GOCS) nanocomposite was applied onto an A...

#6 [11.8] A switchable paper-based aptasensor functionalized with a Cr₂O₃-TiO₂ nanozyme for visual and on-site detection of ochratoxin A in agri-foods

#7 [11.7] Turn-on fluorescent assay based on nitrogen-doped carbon dots and aptamer for low-background detection of kanamycin.

This study presents a low-background "turn-on" fluorescent assay for sensitive trace kanamycin (KANA) detection. Nitrogen-doped carbon dots (N-CDs) efficiently quench ∼80% of the fluorescence of the FAM-labeled KANA Aptamer (F-APT) via electrostatic adsorption, establishing a stable, low-fluorescence baseline. Upon binding KANA, F-APT folds into...

#8 [11.7] Ultrasensitive Detection of Porcine Epidemic Diarrhea Virus Infections Using Multivalent DNA Nanostructure-Enabled Lateral Flow Assay.

Early, rapid on-site detection of viral pathogens in livestock is critical to prevent disease spread, minimize economic losses, and safeguard food security. However, most current diagnostics are limited to centralized laboratories or require specialized equipment such as electrochemical readers, with a few hours to multi-day turnaround times tha...

#9 [11.3] Near-Infrared-Driven Multiplexed, Self-Powered Photoelectrochemical Sensor for Portable and Reliable Detection of Steroid Estrogens.

The development of near-infrared (NIR)-driven photoelectrochemical (PEC) sensors for on-site, multianalyte detection remains challenging owing to the limited NIR responsiveness of photoactive materials and the reliance on complex, externally powered conventional PEC systems. Herein, we report a fully integrated, self-powered multiplexed PEC sens...

#10 [11.3] High-sensitivity electrochemical aptasensor based on AuNPs/NH(2)-UIO-66/PEI/MCNs nanocomposite for endotoxin detection.

Endotoxins, specifically lipopolysaccharides (LPS), are components of the outer membrane of Gram-negative bacteria. Due to the fact that even extremely low concentrations of endotoxins can trigger the human body's inflammatory cascade, there is an urgent need to develop highly sensitive detection technologies for accurate identification and quan...
