#1 [17.6] 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...

#2 [16.5] A particle counting biosensor mediated by Clostridium butyricum argonaute for simultaneous detection of aflatoxin B(1) and ochratoxin A.

The co-contamination of aflatoxin B1 (AFB1) and ochratoxin A (OTA) in environmental foods has attracted widespread attention. A particle counting biosensor was developed for the simultaneous detection of AFB1 and OTA, utilizing polystyrene (PS) microspheres with diameters of 4 μm and 6 μm (PS4μm and PS6μm) as signal probes and aptamers as biolog...

#3 [14.2] Dual enzyme-mimicking Ce-UiO-66-NO(2)-driven autocatalytic cascade signal amplification for split-type electrochemical aptasensing of enrofloxacin.

Enrofloxacin (ENR) is extensively applied in veterinary medicine for controlling infectious diseases. Nevertheless, the presence of ENR residues in animal-derived food products poses considerable threats to human health. Therefore, the development of highly sensitive and accurate analytical techniques for ENR monitoring is urgently required. Her...

#4 [13.1] 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...

#5 [13.0] 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 ...

#6 [11.8] Honeydew: A Fluorescent Aptamer for Low‐Cost Azo Food Dyes

Light‐up RNA aptamers that bind nonfluorescent dyes and conditionally activate their fluorescence are powerful tools for RNA imaging and biomolecular sensing. A barrier to widespread adoption of this technology is a reliance on bespoke dyes prepared by labor‐intensive or costly custom synthesis. Here, we demonstrate that azo dyes—abundant, ultra...

#7 [11.3] A smartphone-integrated portable fluorescent biosensor for on-site detection of antibiotics.

BACKGROUND: The widespread antibiotic residues pose significant risks for public health, food and environmental safety, necessitating rapid on-site monitoring tools, while conventional methods for antibiotics detection often rely on complex instrumentation, limiting their field applicability. This study presented a versatile portable aptasensor ...

#8 [11.1] Aptamer cleavage optimization, binding mechanism elucidation, and application for alternariol enrichment and fluorescence detection in food matrices

#9 [11.1] Harnessing the pyrophosphate-triggered disassembly of MIL-88B(Fe) for in situ dual-signal generation and reliable acetamiprid detection.

This work presents a smartphone-integrated, fluorescence/colorimetric dual-mode sensing platform that combines fluorescence and colorimetric detection with support vector regression (SVR) for monitoring of acetamiprid in food. The system employs a sandwich-structured mechanism using MIPs/Fe3O4 as capture probes and aptamer-functionalized MIL-88B...

#10 [11.0] Breaking the Sensitivity–Sustainability Trade-Off in Heavy Metal Sensing: A DNA Breathing-Actuated Nanoprobe

Currently established heavy metal sensors based on plasmonic nanoparticles often face an intractable trade-off between high sensitivity and sustainability, a dilemma that impedes their real-world application, particularly in resource-limited settings. Here, we report a dynamic DNA interface strategy that breaks this trade-off in Hg(II) ion detec...
