#1 [26.8] 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 [22.7] 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 [15.0] 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...

#4 [14.5] 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...

#5 [13.3] 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...

#6 [13.3] 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...

#7 [12.6] Matrix-first benchmarking of biosensors for multi-hazard monitoring: bacteria, viruses, and pesticides in food and water.

Biosensors are pivotal for detecting foodborne and waterborne hazards due to their portability, low cost, and rapid response. However, performance often degrades in real samples, where complex matrices reduce sensitivity and specificity and increase false positives/negatives. This systematic review synthesizes recent advances in biosensor platfo...

#8 [11.8] Nano-enabled fluorescent sensing platforms for on-site detection of pesticides in food

: Pesticide residues in food matrices pose significant threats to global food safety. Conventional chromatographic methods, though highly reliable, are constrained by high costs, lengthy analysis times, and limited field deployability, restricting their use for rapid on-site monitoring across food supply chains. Nanomaterial-based fluorescent se...

#9 [11.8] Integration of dual-output TMSD and CRISPR/Cas12a for crosstalk-free electrochemiluminescence detection of aflD gene and AFB1.

Aflatoxins are among the most toxic mycotoxins and pose a severe threat to food safety and human health. In addition to the direct monitoring of aflatoxin B1 (AFB1), simultaneous detection of its key biosynthesis gene, aflD, can effectively indicate the presence of toxin-producing strains, thereby enhancing the early screening and traceability o...

#10 [11.6] DNA tetrahedrons based DNA microcapsules for sensitive fluorescence sensing of Staphylococcus aureus.

A sensitive fluorescence (FL) biosensor was developed for the detection of Staphylococcus aureus (S. aureus) using DNA tetrahedrons (DTNs) based stimuli-responsive DNA microcapsules. FAM-labeled DTNs were initially encapsulated within the inner pores of DNA microcapsules. Owing to the physical shielding effect of the DNA shell, no FL signal was ...
