#1 [20.9] Aptamer-cDNA-driven nanozyme strategy: A recyclable dual-signal immunosensor for amplified detection of aflatoxin B(1) in edible oil.

Aflatoxin B1 (AFB1) poses a serious threat to human health, highlighting theurgent need for sensitive, precise and visual detection methods in daily foods. However,traditional detection methods relying on peroxidase (POD)-mimetic activity are susceptible to external interference, which increases false-positive or false-negative rates and comprom...

#2 [16.8] A novel label-free electrochemical aptamer sensor based on base mismatch and strand displacement for detection of kanamycin.

Misuse of kanamycin in animal husbandry has led to serious food safety issues. In this study, a label-free electrochemical aptasensor based on the base mismatch and strand displacement was developed for detection of kanamycin residue in agricultural products. A novel ferrocene-naphthalimide derivative was employed as the electroactive indicator....

#3 [13.5] Aptamer screening within sample matrices: Toward reliable applications.

Nucleic acid aptamers are short oligonucleotide sequences selected in vitro by Systematic Evolution of Ligands by EXponential enrichment (SELEX). As "chemical antibodies", they recognize diverse targets with high affinity and specificity through structure-dependent interactions and offer multiple attractive features. Although a few natural aptam...

#4 [13.3] Inception-level signal amplification: Cascaded DNAzyme-Cas9 nickase achieves sub-nanomolar kanamycin tracking.

BACKGROUND: Kanamycin's persistent contamination in agricultural products poses significant human health risks due to its nephrotoxicity and bioaccumulation via the food chain. Existing methods for on-site kanamycin monitoring lack sufficient sensitivity and portability, limiting their utility in field settings. The urgent need for rapid detecti...

#5 [13.0] Functional nucleic acid-enabled spatially resolved in situ mapping of cross-species molecular landscapes in acute ochratoxin A nephrotoxicity

#6 [12.6] An electrochemiluminescence biosensor for sulfadimethoxine detection based on enzymatic DNA walker-activated CRISPR/Cas12a cascade for signal enhancement.

Sulfadimethoxine (SDM) is a widely used veterinary antibiotic. Its residues in food and the environment may cause bacterial resistance and threaten human health. In this study, a novel electrochemiluminescence (ECL) biosensor with signal amplification was developed for the sensitive detection of SDM. A g-C3N4@Au composite was modified on the ele...

#7 [12.3] Core-shell Au@CeO(2) nanozyme-mediated aptasensor for dual-mode SERS/colorimetric detection of kanamycin.

Kanamycin (KANA), a widely used aminoglycoside antibiotic, may accumulate in food products and pose potential risks to human health, calling for sensitive and reliable analytical strategies. A dual-mode detection method integrating surface-enhanced Raman spectroscopy (SERS) with colorimetric sensing was developed. This approach enabled sensitive...

#8 [12.3] Duplex DNase-powered RNA walker for multiplex fluorescent detection of trace pesticide residues in tea samples.

BACKGROUND: The bipyridine herbicide paraquat (PQ) and the benzimidazole fungicide carbendazim (CBZ) play a key role in weed and fungus control on farmlands to elevate crop output. Yet, excessive deployment of these chemicals risks leaving residues in the food chain, constituting a grave danger to public health. The presence of multiple pesticid...

#9 [12.3] Facilely Synthesized Rough Photothermal Gold Nanoparticles for Portable and Rapid Detection of Staphylococcus aureus

Foodborne infections and enterotoxin poisoning caused by S. aureus pose serious threats to food safety and public health. However, conventional detection methods are often time-consuming, technically complex, and typically require relatively large sample volumes. Herein, we report an aptamer-functionalized rough gold nanoparticle (RPG)-based pho...

#10 [12.0] HCR-assisted CRISPR/Cas12a platform enables logic-gate and multimodal detection of kanamycin and bisphenol A.

A novel triple-modal biosensor integrating hybridization chain reaction (HCR) with CRISPR/Cas12a was developed for sensitive and selective detection of kanamycin (KANA) and bisphenol A (BPA). The system employs a phosphorothioate-modified G-rich hairpin (SHG4-2) as a dual-functional reporter probe, which resists Cas12a trans-cleavage and enables...
