title: Indium Tin Oxide Nanoparticles/Vaseline Nanocomposites: Preparation of Nanoelectrode Assembles with Tunable Dimensions.
abstract: In this paper, we describe a novel approach for fabricating tailor-made indium tin oxide nanoelectrode assembles (ITO-NEAs) based on indium tin oxide nanoparticles (ITONPs) as conducting materials and vaseline as insulating binder. ITO nanoelectrode assembles were formed on the surface of a glassy carbon electrode (GCE) by uniformly covering GCE with ITONPs/vaseline nanocomposite. Cyclic voltammetry (CV) studies demonstrated that the ITO-NEAs exhibit fast mass transport and low charging current, suggesting that the ITO-NEAs, fabricated with ITONPs and vaseline hybrid film coating, behave like a microelectrode array. Furthermore, electrochemical results show the as-prepared ITONPs electrodes have tunable dimensions, ranging from a conventional electrode to a nanoelectrode ensemble, depending on the amount of insulting vaseline dissolved in the ITO-NPs/acetone dispersion. As novel kind of ITONPs-based film electrodes with tunable dimensions and good electrochemical activity, the ITO film electrodes are very attractive for potential application in fundamental and practical electrochemical studies.
