#1 [12.6] Co-enhanced ECL imaging platform based on TiO2 coreactant accelerator and HCR amplification with dual-signal readouts for sensitive aptasensing of aflatoxin B1

#2 [12.3] Programmable Electrochemical Cefapirin AntibioticAptasensor Powered by Highly Conductive Bimetallic NiCu(HITP) MOFand Dendritic DNA Amplifications

Abstract Residues of veterinary antibiotics in animal-derived foods motivate the development of analytical methods that combine high sensitivity with straightforward operation. Cefapirin, a β-lactam used extensively for the treatment of bovine mastitis, may persist in milk and other commodities; therefore, sensitive detection of trace-level cefa...

#3 [12.1] Photo-driven gated dual-mode aptasensor based on CQDs@PCN-224@ZIF-8 and Exo I-HCR cascade amplification for ultrasensitive bisphenol A detection.

Dual-mode biosensors offer an effective strategy for reducing signal ambiguity and improving the reliability of trace small-molecule detection. However, integrating photo-driven transduction, fluorescence modulation, and nucleic acid cascade amplification into a single sensing system remains challenging. Herein, a photo-driven fluorometric/color...

#4 [12.1] An innovative immobilization-free homogeneous electrochemical strategy facilitated by buoyancy -magnetism separation for evaluating the acetamiprid in food.

An innovative enzyme-free and immobilization-free homogeneous electrochemical sensing strategy mediated by buoyancy-magnetism separation cooperation with Fe3O4@Ag was designed for the sensitive detection of acetamiprid (ACE). This approach ingeniously integrates hollow silica microspheres (HSB) as suspension recognition units with Fe3O4@Ag as ma...

#5 [11.7] Phosphorothioate-Enabled Cas12a Autocatalytic Networkfor Amplification-Free Ultrasensitive Nucleic Acid Detection

Abstract Autocatalytic CRISPR/Cas systems offer a promising route toward amplification-free nucleic acid detection, yet their performance is limited by indiscriminate transcleavage of ssDNA activators and the reliance on structurally complex, thermodynamically unstable DNA architectures. A phosphorothioate (PS)-enabled Cas12a autocatalytic netwo...

#6 [11.5] Au NPs-Induced ligand-defective Ce MOF boosting oxidase-like activity for colorimetric aptasensor platform construction.

In this study, Au NPs were substituted for a H2BDC ligand on the Ce MOF, resulting in ligand-defective Au@Ce MOF. The coordination environment of the cerium metal sites is effectively disrupted, leading to the formation of electron-enriched Au-O-Ce interface. It results in reduction of the electron density on the Ce MOF surface and lowering of t...

#7 [11.5] A multifunctional electrode interface: A hybrid hexanethiol and polyethylene glycol monolayer for concurrent anti-fouling, stability, and ultrasensitive detection of ochratoxin A.

Integrating antifouling capability, operational stability, and high sensitivity into electrochemical biosensors in a simple and cost-effective manner remains a significant challenge. Herein, we present a multifunctional biointerface based on a hybrid hexanethiol and polyethylene glycol (HT-PEG) self-assembled monolayer (SAM) that concurrently ad...

#8 [11.5] Spatially and potential-resolved anti-interference ECL biosensor for simultaneous detection of ochratoxin A and aflatoxin B(1).

The simultaneous detection of multiple targets using electrochemiluminescence (ECL) is often hampered by the interference between lumiphores. To address this challenge, a spatially and potential-resolved ECL biosensor was developed for the detection of ochratoxin A (OTA) and aflatoxin B1 (AFB1). Specially, graphitic carbon nitride @ silicon diox...

#9 [11.1] Engineered aptamer-confined hydrogel for label-free detection of heavy-metal ions with enhanced interference tolerance.

Aptamer misfolding induced by complex sample matrices often compromises target recognition. Herein, we developed a hydrogel-confinement strategy to stabilize aptamer conformation and effectively suppress matrix interference. Using Pb2+ as a model analyte, aptamers were immobilized during in situ hydrogel polymerization, which helped maintain key...

#10 [10.5] Photoelectrochemical and colorimetric dual-mode aptasensor for nonylphenol detection in food based on ascorbic acid-sensitive Bi(2)S(3)/Bi(2)O(2)CO(3) heterojunction and multi-enzyme-mimicking Ce-MOF.

A simple and novel photoelectrochemical (PEC)-colorimetric (CL) dual-mode aptasensor was explored for nonylphenol determination using ascorbic acid (AA)-sensitive Bi2S3/Bi2O2CO3Z-Scheme heterojunction and Ce(III/IV)-MOF (R-UiO66-Ce) with dual enzyme-mimetic activity. Firstly, ascorbic acid phosphate was hydrolyzed under R-UiO66-Ce catalysis to g...
