#1 [25.0] Ultrasensitive photoelectrochemical aptasensor for sulfadiazine detection enhanced by taxifolin-boosted 3D porous g-C(3)N(4).

Photoelectrochemical (PEC) sensing based on graphitic carbon nitride (g-C3N4) has promising attention due to its low background signal; however, its performance is hindered by charge carrier recombination. Herein, a high-performance PEC aptasensor was developed for ultrasensitive sulfadiazine (SDZ) detection using taxifolin-functionalized three-...

#2 [21.1] 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 [18.8] A comprehensive review of biosensors for environmental estrogens: Design and performance.

Environmental estrogens (EEs) persist ubiquitously in the environment, posing significant threat to human health and ecosystems. Over recent decades, biosensors have emerged as pivotal tools for EEs detection, the advancement of nanomaterials and signal amplification strategies has substantially enhanced biosensor performance, enabling properly ...

#4 [18.8] Molecular filling and metal ion-mediated DNA self-assembly strategy enable evaluation of lung cancer metastasis.

Accurately assessing the risk of lung cancer metastasis is crucial for improving patient prognosis and quality of life. In this study, we developed a rapid, homogeneous fluorescence detection system (DNA-N@Ag+@PIX) for lung cancer mesenchymal circulating tumor cells (M-CTCs) based on a molecular filling strategy and metal ion-mediated DNA self-a...

#5 [18.4] 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...

#6 [17.9] Single-sequence based gFET-aptasensors for the discrimination of apo- and holo-RBP4 in human serum.

Retinol-binding protein 4 (RBP4) is a key transporter of all-trans-retinol (vitamin A), circulating in blood as either holo-RBP4 (retinol-bound) or apo-RBP4 (retinol-free). Dysregulated RBP4 levels, particularly an imbalance between apo- and holo-RBP4, have been implicated in a range of metabolic and cardiovascular diseases. Current detection me...

#7 [15.0] Topology-Gated λ Exonuclease Enables Amplification-Free Signal Boosting.

Amplification-free detection remains a fundamental challenge in CRISPR-based RNA diagnostics. Here, we identify a previously unrecognized topological property of λ exonuclease, whereby duplex substrates bearing 5' phosphates at both termini undergo a self-sustained cyclic cleavage-reforming process. This topology-gated behavior enables signal re...

#8 [14.7] Radical‐Mediated In Situ Fluorescence Dye Deposition: A Simple Interfacial Signal Amplification Reaction for Ultrasensitive Immunoassay on Barcode Beads

Ultrasensitive detection of low-abundance protein biomarkers is crucial for early disease diagnosis but remains challenging for the conventional barcode beads-based suspension chip platform due to the limited detection sensitivity. Here, we report a conceptually novel reaction termed "radical-mediated in situ fluorescence dye deposition" (RIFD) ...

#9 [14.0] Electrochemical biosensors for MLKL-related necroptosis biomarkers in lung cancer: From bench to clinical laboratory.

Lung cancer continues to be a leading cause of cancer-related mortality globally, necessitating the development of enhanced biomarkers for early detection and ongoing disease monitoring in clinical practice. Current diagnostic methodologies predominantly rely on imaging and tissue biopsy, which may not sufficiently capture the dynamic molecular ...

#10 [14.0] Regenerable “Two-in-One” molecularly imprinted nanozymes colorimetric sensor array combined with deep learning enables selective removing and visual discriminate of tetracycline antibiotics
