Nafion-stabilized magnetic nanoparticles (Fe3O4) for [Ru(bpy)3]2+(bpy = bipyridine) electrogenerated chemiluminescence sensor

Abstract

A highly sensitive and stable [Ru(bpy)3]2+ ECL sensor has been fabricated based on the multilayer films of Nafion-stabilized magnetic nanoparticles (Nafion/Fe3O4) formed on a platinum electrode surface by means of an external magnet.

Perfluorosulfonate ionomer membranes with improved through-plane proton conductivity fabricated under magnetic field

“…In this work, we have synthesized Fe 3 O 4 nanoparticles in-situ in PFSI solution similar to Kim et al [21] reported. This prestabilization procedure could solve the above mentioned problems successfully, although the interaction mechanism between Fe 3 O 4 and PFSI is unclear and need further investigation.…”

Applications of Nanomaterials in Electrogenerated Chemiluminescence Biosensors

“…Other nanomaterials, such as SiO 2 [54], clay [55], Fe 3 O 4 [56], and Zeolite Y sieves [57], are also used as electrode modification materials to construct functionalized electrode interfaces for ECL biosensors. These materials have a high chemical inertness and provide a wide range of anode working potentials with low electrical resistivity.…”

“…The ECL sensor was fabricated based on the multilayer films of Nafion-stabilized magnetic nanoparticles (Nafion/Fe 3 O 4 ) formed on a platinum electrode surface by means of an external magnet. The ECL sensor based on the Nafion/ Fe 3 O 4 multilayer films is more sensitive than that based on pure Nafion films, which is maybe due to the fast mass transport in the Nafion/Fe 3 O 4 multilayer films [56]. …”

Thermal oxide synthesis and characterization of Fe3O4 nanorods and Fe2O3 nanowires

“…Nanoscale Fe 3 O 4 has been applied in magnetic ink [3] , electronics and bio-sensitive materials [4,5] , high density magnetic recording media and biomedical fields [6][7][8][9] , because of its good compatibility with organism and its electrical and magnetic characteristics of its size and morphology. Therefore, the preparation of Fe 3 O 4 nanostructures and its properties research are extremely active in recent years.…”
