#1 [21.3] 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 [14.8] 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...

#3 [14.0] 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...

#4 [13.3] 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...

#5 [13.3] Multivalent Aptamer–Mediated Competitive Control of CRISPR/Cas12a Enables Amplification-Free Electrochemical Detection of Salmonella Typhimurium

#6 [13.1] 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...

#7 [13.0] Photoelectrochemical aptasensor based on biomass-derived carbon/BiOI nanoflowers for in-situ monitoring of abscisic acid.

A photoelectrochemical (PEC) aptasensor based on bismuth oxyiodide (BiOI) nanoflower/biomass carbon (BiOI@BC) was fabricated for in-situ detecting abscisic acid (ABA) in tomato leaves under salt stress. Shrimp shells-derived biomass carbon acted as an enhanced carrier, and the biomass carbon improves the PEC performance of BiOI by extending the ...

#8 [13.0] Nanoparticles-assisted SELEX strategies for aptamer screening: a comprehensive review.

Aptamers, short oligonucleotide strands hold excellent potential for diverse applications in the field of biomedicine and bioanalytics such as drug delivery, bioimaging, biosensors, therapy and theranostics, thereby emerging as potential alternatives to antibodies. Since the introduction of SELEX (Systematic Evolution of Ligands by Exponential E...

#9 [12.6] 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 ...

#10 [12.6] 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 ...
