#1 [26.3] 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 [12.6] 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...

#3 [12.6] 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...

#4 [12.1] 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...

#5 [12.0] 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...

#6 [11.7] Fluorescence “Turn-On” Detection of Bisulfite via Specific CN Bond Cleavage: Reactivity, Structure−Property Relationship, and Bioimaging Applications

Abstract It is essential to detect HSO3− for ensuring food safety, preventing environmental pollution, and safeguarding human health. We report a new approach for the fluorescence recognition of HSO3−. The key principle lies in exploiting the specific and irreversible cleavage of the CN bond in the probe’s Schiff base structure by HSO3− to achi...

#7 [11.2] Aptamer-grafted amino-functionalized covalent organic frameworks for simultaneous exceptional selectivity and high-capacity adsorption of four aflatoxins.

Precise quantification of aflatoxins in complex food matrices remains challenging because of substantial matrix interference. In this work, an aptamer-grafted amino-functionalized covalent organic framework (Apt@NH2-COF) was developed through covalent immobilization of aptamers using a heterobifunctional crosslinker. The introduced aptamers sign...

#8 [11.1] Harigabri-Derived Carbon Dots as FRET Probes for E. coli Analysis.

Green-fluorescent carbon quantum dots (CQDs) were hydrothermally synthesized from the Mongolian medicine Harigabri, exhibiting uniform size (∼2.5 nm) and strong emission at 521 nm under 468 nm excitation. Based on the fluorescence resonance energy transfer (FRET) between the CQDs (donors) and AgNPs (acceptors), an aptamer-functionalized biosenso...

#9 [11.0] A self-powered photoelectrochemical aptasensor based on core-shell Z-scheme Co(3)O(4)@ZnO/ZnO@Co(3)O(4) heterojunction and bimetallic zeolitic imidazolate framework-derived templates for ultrasensitive detection chlorpyrifos.

Pesticide residues pose a serious threat to food safety and public health, making the development of rapid and sensitive on-site detection technologies a major challenge. Here a self-powered photoelectrochemical aptasensor is reported for ultrasensitive detection of chlorpyrifos in food samples. The sensor is based on a Z-scheme Co3O4@ZnO/ZnO@Co...
