#1 [13.0] 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...

#2 [12.8] 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...

#3 [12.8] 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...

#4 [12.3] 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...

#5 [12.2] 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...

#6 [12.2] 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...

#7 [12.2] 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...

#8 [11.8] 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...

#9 [11.1] 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...

#10 [11.0] A Fossilization-Inspired Photoelectrochemical Sensing Platform: DNA-Induced In Situ CaCO3 Crystal Growth Modulates The Photoelectrochemical Response of Gold Electrodes for Ultrasensitive Aflatoxin B1 Detection.

Although photoelectrochemical (PEC) sensing offers low background and high sensitivity, most PEC platforms rely on semiconductor materials and immobilized recognition probes, which complicate electrode fabrication and reduce operational simplicity. Herein, we report a fossilization-inspired photoelectrochemical sensing platform (FIPSP) for ultra...
