#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 [14.8] Precision chemical engineering of dendrimers for nucleic acid delivery

#9 [14.7] Programmable DNA-Based Dimerization Networks for Dynamic and Competitive Control of Transcription.

Here, we introduce a minimal, experimentally validated DNA-encoded analogue of many-to-many protein dimerization networks to achieve programmable control of cell-free transcription. To do so, we rationally designed DNA monomers bearing orthogonal azide or DBCO handles that assemble via SPAAC chemistry into a combinatorial library of covalent dim...

#10 [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) ...
