#1 [15.2] 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 [13.1] PdIr bimetallic nanozyme engineered metal-organic frameworks integrated dual-mode sensor toward Stx2 detection in food.

Shiga toxin II (Stx2) has attracted extensive attention due to its toxicity and pathogenicity, making the development of sensitive detection methods urgent. This study constructed a dual-mode sensing platform for the sensitive detection of Stx2 in food. Composite material UIO-66@PdIr with peroxidase-like activity and fluorescent properties was s...

#3 [13.0] Defect-Engineered Fe-B MOFs with Intrinsic Neutral-pH Recognition for Accelerated Dual-Mode Detection of Staphylococcus aureus.

This study addresses the challenge of achieving sensitive and reliable Staphylococcus aureus detection in neutral-pH food matrices, where conventional boronate affinity ligands typically lose their binding efficiency. We developed a dual-mode colorimetric-electrochemical aptasensor by rationally designing a defect-engineered iron-boronic acid me...

#4 [12.6] Bimetallic valence relay catalysis in EuTb/N-doped carbon nanosheets: temporal decoupling of oxygen reduction resolves competitive kinetics for ultrasensitive electrochemiluminescence detection of L-cysteine

Accurate monitoring of thiol-containing biomolecules is crucial for understanding redox balance in biological systems. However, conventional luminol-based electrochemiluminescence (ECL) systems rely on unstable H2O2 or suffer from low dissolved O₂ solubility and sluggish kinetics, leading to insufficient reactive oxygen species (ROS) generation ...

#5 [12.2] Porous Hydrogel-Mediated One-Step Selection of Mannoprotein-Targeted Aptamers for Early Diagnosis of Invasive Saccharomyces cerevisiae Infections.

Invasive fungal infections, particularly those caused by Saccharomyces cerevisiae, have emerged as a significant public health threat. Accurate and timely recognition of S. cerevisiae is essential for effective diagnosis and treatment. This study introduces a micro- and nanoscale-enabled diagnostic strategy that integrates porous hydrogel-mediat...

#6 [11.9] Novel Electrochemical Aptasensor Based on Iron–Cobalt-Doped Magnetic Carbon and cDNA-Polyacrylic Acid for the Determination of Aflatoxin B1 in Peanuts

The presence of aflatoxin B1 (AFB1) is ubiquitous in the environment, and it is considered one of the most powerful natural carcinogenic substances. In this study, a highly sensitive electrochemical aptasensor was designed to detect aflatoxin B1 (AFB1) in peanuts. Iron–cobalt-doped magnetic carbon (Fe-Co/NPC) was used to enhance the conductivity...

#7 [11.6] Sulfur vacancy-mediated self-photocatalysis-boosted electrochemiluminescence sensing via molecular oxygen activation for sensitive detection of isocarbophos.

The luminol-dissolved oxygen electrochemiluminescence (ECL) system is fundamentally limited by the poor redox activity of oxygen, which fails to generate sufficient reactive oxygen species (ROS) for efficient luminol excitation, restricting the performances of sensors. Herein, a high-performance ECL sensor was fabricated for sensitive detection ...

#8 [11.4] A fluorescent aptasensor based on the synergy of Au NPs/PDDA/LEG nanocomposite and CDs for aflatoxin B1 detection.

Aflatoxin B1 (AFB1), a potent carcinogen produced by Aspergillus fungi, contaminates foods such as corn and peanuts and thereby introduces a serious food safety risk, as it is known to cause liver damage and cancer. Therefore, developing sensitive and rapid detection methods is crucial for protecting public health. This work presented a highly s...

#9 [11.3] A Triple-Signal Output Lateral Flow Platform Leveraging CRISPR/Cas12a and Nanozyme Cascades for Ultra-Sensitive Aflatoxin B1 Detection.

The presence of the potent carcinogen aflatoxin B1 (AFB1) in agricultural products poses a grave threat to food safety and human health, underscoring the imperative development of highly sensitive detection methodologies. Despite the considerable efforts that have been dedicated to aptamer-based biosensors, the sensitivity of typical nucleic aci...

#10 [11.0] Starfish-like gold nanotags aggregation induced high density hot-spots to boost surface-enhanced Raman scattering signals for ultrasensitive detection of foodborne pathogens.

Aspergillus niger, a key functional microorganism widely employed in food fermentation processes, also poses significant health risks as numerous strains are capable of producing hazardous mycotoxins. This nature necessitates the development of rapid and accurate detection techniques. In this study, a highly sensitive surface-enhanced Raman scat...
