#1 [18.4] A bifunctional triblock zwitterionic copolymer combined with gold nanostars for antifouling electrochemical aptasensor to detect chloramphenicol in food samples.

To address the issue of electrochemical sensors being susceptible to fouling interference in complex food matrices, this work proposed a high-performance antifouling aptasensor based on a triblock zwitterionic copolymer and a gold nanostars (Au NSs) conductive substrate. Through precise control over the composition of two zwitterionic monomers [...

#2 [13.6] Engineering of magnetic peroxidase-like heterojunction nanozymes from homogeneous iron precursor by surface-initiated encapsulation for self-calibration colorimetric/fluorescence dual-mode analysis of Hg(2 +) ion in foods.

The engineering of multi-modal optical sensors with improved detection accuracy is still a hot topic. Herein, the homologous heterostructured nanozyme with enhanced peroxidase (POD)-like activity was prepared by surface-initiated encapsulation of porphyrin-based metal-organic frameworks on magnetic ferroferric oxide (Fe3O4@TCPP-Fe) for self-cali...

#3 [13.3] Molecular recognition elements-integrated multimodal nanosensing of aflatoxin B1: design principles and self-calibrating paradigms.

Aflatoxin B1 (AFB1) is a potent hepatocarcinogenic mycotoxin that poses severe health risks through contaminated agricultural products. Rapid, sensitive, reliable, and field-deployable detection methods are therefore critical for food safety. Conventional instrumental techniques suffer from high cost, complex operation, and unsuitability for on-...

#4 [13.3] Sequential fluorescence modulation in an aptamer-functionalized bimetallic Ni/Fe-MOF for smartphone-assisted ratiometric detection of Staphylococcus aureus.

Fluorescence modulation through enhancement and spectral tuning is important for improving the analytical performance of luminescence-based sensing platforms. In this study, a label-free fluorescent aptasensor was developed by functionalizing a bimetallic nickel-iron metal-organic framework (Ni/Fe-MOF) with a specific single-stranded DNA aptamer...

#5 [12.7] Engineering a Lab-Free Microfluidic Chip Biosensor Integrating Immuno-Proximity Ligation and On-Cleavage RCA for Multiplex Meat Adulteration Monitoring

Abstract Traditional analytical methods for food authentication heavily rely on laboratory-based instrumentation and inconsistent operational procedures, limiting their practical applicability for on-site identification in complex food markets. Herein, a lab-free centrifugal microfluidic chip-based biosensor was developed for the simultaneous id...

#6 [12.3] Machine learning-assisted ultrasensitive paper-based electrochemical sensor with aptamer-molecularly imprinted polymer dual recognition for aflatoxin B1 detection.

Aflatoxin B1 (AFB1) is a highly hazardous Group Ⅰ carcinogen that widely contaminates grain products. To realize rapid on-site detection, we developed an electrochemical sensor based on electrochemically modified graphene-carbon nanotube composite paper (EMCP), Prussian blue (PB), Au-Ag bimetallic nanoparticles and an aptamer-molecularly imprint...

#7 [12.0] A novel fluorescent aptasensor leveraging Exonuclease III-mediated signal amplification and MnO(2) nanoflowers for ochratoxin A detection.

The objective of this research was to establish an ochratoxin A (OTA) detection system. The aptamer has the ability to specifically recognize and bind to OTA. This recognition-binding action triggers a hybridization event. During this event, the complementary DNA (c-DNA) strand hybridizes with the signal probe (SP), thereby forming a double-stra...

#8 [11.8] Aptamer-functionalized solution-gated graphene transistor for rapid detection of trace scandium.

The growing exploitation of rare earth resources has led to the migration and accumulation of Scandium (Sc) within food systems, giving rise to emerging food safety concerns. Conventional techniques for Scandium (III) ions (Sc3+) detection are limited by labor-intensive sample preparation, high instrumentation costs, and poor suitability for rap...

#9 [11.6] Broad-spectrum aptamers: recent advances in selection strategies, structural mechanisms, and biosensing applications.

Broad-spectrum aptamers are single-stranded DNA or RNA molecules capable of recognizing multiple structurally or functionally related targets through adaptable molecular interactions. The increasing demand for rapid, efficient, and multi-analyte detection in complex analytical systems has exposed the limitations of conventional single-target apt...

#10 [11.5] CRISPR/Cas12a-powered self-sustaining catalytic nucleic acid circuit for highly sensitive detection of aflatoxin B1.

Aflatoxin B1 (AFB1) is a highly toxic mycotoxin and strongly carcinogenic and teratogenic to humans. Achieving CRISPR-based sensing system for highly sensitive detection of AFB1 remains a significant challenge. A CRISPR/Cas12a-powered self-sustaining catalytic nucleic acid circuit (CPSCN) is proposed for the sensitive and accurate detection of a...
