Abstract

An innovative construction approach relies on incorporation of gold nanoparticles (AuNPs) as a sandwich linking species between two assembled layers composed of tris(2,2′-bipyridyl)ruthenium(II), Ru(bpy)₃²⁺. The entire luminescent system is doped at an alkaline treated polymeric film made of poly(4-aminodiphenylamine), t-Padpa, originally deposited at the glassy carbon electrode by repetitive electrochemical scanning. The surface morphology and the composition of the proposed (Ru.AuNPs.Ru.t-Padpa) sensor along with its electrochemical properties were studied using Atomic Force Microscopy (AFM), X-Ray Photoelectron Spectroscopy (XPS) and Electrochemical Impedance Spectroscopy (EIS) methods The analytical performance of the developed sensor and its stability were tested using tripropyl amine (TPA) as a typical co-reactant in the development of ECL sensors. The ECL system shows a remarkable sensitivity towards TPA quantification with a detection limit (3σ) of 10 nM (1.4 ppb). The proposed sensor exhibited a greater efficiency and higher stability over the native ruthenium doped polymer (Ru.t-Padpa) evaluated by its performance for a certain shelf life-time. The present approach confirms the fabrication of a robust and efficient sensor characterized by the parallel operative effects of both AuNPs and the available concentrated surface luminescent molecules.
