#1 [21.7] 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 [12.8] 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...

#3 [12.6] 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...

#4 [12.5] 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...

#5 [11.9] 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...

#6 [11.9] Integrated Antigen–DNA Co‐Detection Using Digital Microfluidics for Improving Diagnostic Accuracy in POCT Analysis

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 microfluidics...

#7 [11.8] SERS-based aptasensor for mycotoxin detection in wheat sprouts in the field

#8 [11.8] Comparative evaluation of high-performance aptamers to construct aggregation-induced emission-based DNA hydrogels for sensitive tetrodotoxin detection.

Ingestion of the highly toxic tetrodotoxin (TTX) poses a serious threat to human health, making the development of sensitive and accurate analytical methods urgently necessary. Recognition molecules are critical for achieving high-sensitivity detection. Here, we aimed to rationally evaluate aptamers with high affinity, stability, and specificity...

#9 [11.5] Dual-signal fluorescent-colorimetric aptasensor for tobramycin detection in milk based on fluorescent magnetic nanoparticles and AuNPs.

Tobramycin (TOB) is an aminoglycoside antibiotic employed in human and veterinary medicine whose residues in food raise safety concerns. To resolve this issue, we developed a dual-mode aptamer-based sensor for sensitive TOB detection via fluorescence and colorimetric signals. The platform utilizes fluorescent magnetic nanoparticles (FMNs) conjug...

#10 [11.3] A machine learning-optimized bivalent aptasensor based on exonuclease Ⅰ amplification for trace okadaic acid detection

Consumption of okadaic acid (OA)-contaminated seafood endangers human health, highlighting the need for sensitive quantitative detection. Herein, a convenient and highly sensitive bivalent aptasensor was developed for fluorescence detection of OA in aquatic products. The aptasensor was constructed using a bivalent aptamer (B-Apt) as the recognit...
