#1 [19.4] 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 [17.6] 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 [15.2] 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 [12.0] 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 ...

#5 [11.8] 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...

#6 [11.7] 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...

#7 [11.6] Bimetallic synergy and aggregation-induced emission enhanced electrochemiluminescence aptasensor for detection of aflatoxin B1

#8 [11.6] Re-selection of DNA aptamers for acetamiprid for light-up fluorescent detection

Acetamiprid is currently the only member of second-generation neonicotinoid insecticides permitted for open-field use within the European Union following the ban of other neonicotinoids. Its potential environmental and health risks underscore the need for reliable detection methods. Although an acetamiprid aptamer was previously reported, its wi...

#9 [11.5] Construction of an electrochemical biosensor based on Au@MOF-COF nanocomposites for the detection of acetamiprid in traditional Chinese medicine

The development of high-performance electrochemical aptamer-based sensors represents one of the effective strategies for addressing the intractable issue of pesticide residues that pose a threat to human health. Functional nanomaterials are pivotal to enhancing the analytical performance of such sensors. Herein, a multifunctional Au@MOF-COF nano...

#10 [10.8] Development of an ultrasensitive magnetic biosensing platform using SERS and aptamer for the ratio detection of chlorpyrifos in tea.

The rapid and accurate detection of chlorpyrifos (CPF), a widely used pesticide in agricultural products, is crucial for food safety assurance. While traditional methods like HPLC and GC-MS are accurate, they remain costly, slow, and lack portability. Herein, an ultrasensitive magnetic biosensing platform was developed for the ratiometric detect...
