#1 [18.4] 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 [17.0] 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 [14.7] 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 [13.3] 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 ...

#5 [12.1] 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...

#6 [11.6] 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 ...

#7 [11.5] Aptamer cleavage optimization, binding mechanism elucidation, and application for alternariol enrichment and fluorescence detection in food matrices

#8 [11.5] 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...

#9 [11.3] 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...

#10 [11.3] Bimetallic synergy and aggregation-induced emission enhanced electrochemiluminescence aptasensor for detection of aflatoxin B1
