Fabrication of an all-in-one self-enhanced solid-state electrochemiluminescence sensing platform for the selective detection of spermine.

The fabrication of an all-in-one solid-state ECL sensing platform is beneficial not only for expediting the miniaturization of sensing devices, but also, more importantly, for enabling point-of-care applications. In the present work, a self-enhanced solid-state ECL sensing platform is fabricated using newly synthesised silica polyethylene nanoparticles (SiO-PEI NPs) which generate a co-reactant and easily self-assemble with Ru(bpy) and shows selective and sensitive detection of spermine at physiological pH (7.4).

Tris(2,2'-bipyridyl)ruthenium (II) complex as a universal reagent for the fabrication of heterogeneous electrochemiluminescence platforms and its recent analytical applications.

In recent years, electrochemiluminescence (ECL) has received enormous attention and has emerged as one of the most successful tools in the field of analytical science. Compared with homogeneous ECL, the heterogeneous (or solid-state) ECL has enhanced the rate of the electron transfer kinetics and offers rapid response time, which is highly beneficial in point-of-care and clinical applications. In ECL, the luminophore is the key element, which dictates the overall performance of the ECL-based sensors in various analytical applications.

Study of highly stable electrochemiluminescence from [Ru(bpy)]/dicyclohexylamine and its application in visualizing sebaceous fingerprint.

For the first time, we report a novel and highly stable visual electrochemiluminescence emission from the [Ru(bpy)]/dicyclohexylamine system at physiological pH conditions, with a quantum efficiency () of 95.5%. Furthermore, we have successfully demonstrated the simple and rapid smartphone-based ECL mapping of sebaceous fingerprints a non-destructive mode.

Bimodal Electrogenerated Chemiluminescence of the Luminol/Dicyclohexylamine (DCHA) System: A Novel and Highly Sensitive Detection of DCHA via ECL-Flow Injection Analysis.

Though luminol is one of the most prominent and extensively studied luminophores in ECL studies, only HO has been widely used as a co-reactant. This limits the variety of applications because of the short-time radical stability and low quantum efficiency. In the present work, we identified dicyclohexylamine (DCHA) as a new and highly efficient anodic co-reactant in ECL for the luminol molecule.
