#1 [22.6] 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 [13.7] Strain-Level Food Surveillance of Escherichia coli Using a Specific-Nonspecific Hybrid Sensor Array Strategy.

Array-based sensing platforms have advanced rapidly in recent years, offering strong potential for high-throughout and multiplexed detection. However, their practical translation in food safety remains constrained by insufficient selectivity in complex matrices. Here, we report a synergistic sensing strategy that integrates specific and cross-re...

#3 [13.6] Multivalent Aptamer–Mediated Competitive Control of CRISPR/Cas12a Enables Amplification-Free Electrochemical Detection of Salmonella Typhimurium

#4 [13.5] 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...

#5 [13.0] 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 ...

#6 [12.9] Sensitive detection of aflatoxin B1 using a dual-mode fluorescent aptasensor based on cascade signal amplification.

Aflatoxin B1 (AFB1) is considered a potent carcinogenic mycotoxin and is commonly found in cereals and food products; therefore, its ultrasensitive detection is of great importance to public health. In this study, we developed an innovative dual-mode fluorescent aptasensor based on the entropy-driven strand displacement reaction (ESDR), rolling ...

#7 [12.7] 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 ...

#8 [11.7] 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...

#9 [11.5] A switchable paper-based aptasensor functionalized with a Cr₂O₃-TiO₂ nanozyme for visual and on-site detection of ochratoxin A in agri-foods

#10 [11.4] 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...
