#1 [26.3] 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...

#2 [20.3] 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 [17.7] 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] 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 [13.0] 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...

#6 [12.5] 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...

#7 [12.1] 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...

#8 [12.0] A Colorimetric Aptasensor for Rapid Detection of Sulfadimethoxine in Aquaculture

Sulfadimethoxine (SDM) is a sulfonamide antibiotic widely used in the aquaculture of aquatic organisms. Its excessive residues in animal-derived food products can cause irreversible harm to human health and the environment. Current primary detection methods for SDM, such as instrumental methods and Immunoassay techniques, demonstrate high sensit...

#9 [11.8] CRISPR-responsive hybrid MOF assembling assay for rapid electrochemical detection of domoic acid.

Domoic acid (DA), a potent neurotoxin, poses a serious threat to food safety and public health. Traditional detection methods often struggle to balance sensitivity with practical applicability. To address this, we developed an electrochemical biosensor based on a CRISPR-responsive hybrid metal-organic framework (MOF) assembling assay. This platf...

#10 [11.8] Coordination‐Driven Metal‐Phenolic Network Complexes for Programmable Colorimetric Signal Transduction and Defined Nano‐Bio Interfaces

Self-assembled coordination networks provide opportunities to engineer functional nanostructures with programmable physicochemical properties, yet their optical responses and nano-bio interfacial interactions remain poorly understood. Herein, we employ a coordination-driven self-assembly approach to construct metal-phenolic network complexes (MP...
