Single-Electrode Flow Cell for Electrochemiluminescent Flow Analysis.

Flow injection analysis and liquid chromatography are frequently combined with electrochemiluminescence (ECL) for flow analysis. Almost all electrochemistry flow analyses employ traditional three-electrode electrochemical flow cells which have working electrode, counter electrode, and reference electrode; however, it is expensive and difficult to fabricate a traditional three-electrode electrochemical flow cell and inconvenient to renew the electrode. In this study, we have developed a single-electrode flow cell using commercially available conductive polyethylene film as the only electrode through potential differences induced by the electrode resistance for the first time.

Signal-On Detection of Dopamine and Tyrosinase Using Tris(hydroxypropyl)phosphine as a New Lucigenin Chemiluminescence Coreactant.

Dopamine (DA) is a very imperative neurotransmitter in our body, since it contributes to several physiological processes in our body, for example, memory, feeling, cognition, cardiovascular diseases, and hormone secretion. Meanwhile, tyrosinase is a critical biomarker for several dangerous skin diseases, including vitiligo and melanoma cancer. Most of the reported chemiluminescent (CL) methods for monitoring DA and tyrosinase are signal-off biosensors.

Metal-Organic Framework-Derived High-Entropy Oxides as Coreaction Accelerators for an Efficient Luminol/Dissolved Oxygen Electrochemiluminescence System for Ultrasensitive Mercury Detection.

The development of luminol-dissolved O (luminol-DO) electrochemiluminescence (ECL) systems is crucial for real-world applications. Despite its stability and low biotoxicity, luminol-DO ECL systems struggle with low ECL performance due to their low reactivity. Investigating new materials like coreactant accelerators increases reactive oxygen species (ROS) formation and enhances luminol-DO ECL intensity.

Remarkably Enhanced Luminol/HO Chemiluminescence with Excellent Peroxidase-like Activity of FeCoNi-based Metal-Organic Xerogels for the Sensitive Detection of Dopamine.

Metal-organic gels (MOGs) are a category of metal-organic smart soft materials with large specific surface areas, loose porous structures, and open metal active sites. In this work, trimetallic Fe(III)Co(II)Ni(II)-based MOGs (FeCoNi-MOGs) were synthesized at room temperature via a simple and mild one-step procedure. Fe, Co, and Ni were the three central metal ions in it, while 1,3,5-benzenetricarboxylic acid (HBTC) served as the ligand.
