#1 [19.4] 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 [13.0] 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...

#3 [12.6] 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...

#4 [12.4] 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...

#5 [12.1] 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...

#6 [12.0] 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...

#7 [11.8] 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...

#8 [11.2] Integrated Antigen–DNA Co‐Detection Using Digital Microfluidics for Improving Diagnostic Accuracy in POCT Analysis

ABSTRACT Simultaneous detection of protein and nucleic acid (NA) provides complementary information essential for accurate analysis of complex samples. Conventional approaches for the analysis of protein and NA typically rely on separate workflows and instruments, limiting the reliability of point‐of‐care testing. Here, we present a digital micr...
