#1 [17.0] 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 [14.0] 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...

#3 [13.2] 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...

#4 [12.6] 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 ...

#5 [12.4] 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...

#6 [12.3] 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...

#7 [12.0] 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...

#8 [11.7] 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...

#9 [11.7] Label-Free Electrochemical CRISPR Platform Gated by Allosteric Transcription Factors for Ultrasensitive Small-Molecule Detection

The highly sensitive analysis of small-molecule targets holds profound significance across diverse fields, ranging from clinical diagnosis and environmental monitoring to food safety. Herein, we developed a label-free electrochemical CRISPR platform gated by allosteric transcription factors (aTFs) for the ultrasensitive detection of various smal...
