Here we describe the fabrication of a highly sensitive and label-free ITO-based impedimetric immunosensor for the detection of pathogenic bacteria Escherichia coli O157:H7. Anti-E. coli antibodies were immobilized onto ITO electrodes using a simple, robust and direct methodology. First, the covalent attachment of epoxysilane on the ITO surface was demonstrated by Atomic Force Microscopy and cyc...

The initial stage of indium tin oxide (ITO) thin film growth, deposited by reactive thermal evaporation (RTE), was investigated using atomic force microscopy (AFM) measurements. Five ITO thin films were deposited by RTE of an In:Sn alloy in the presence of added oxygen on heated oxide substrates (Ts=440 K), with film thickness as the deposition variable. Surface imaging as well as statistical a...

Low-temperature growth of indium tin oxide (ITO) nanowires (NWs) was obtained on catalyst-free amorphous glass substrates at 250 °C by Nd:YAG pulsed-laser deposition. These ITO NWs have branching morphology as grown in Ar ambient. As suggested by scanning electron microscopy (SEM) and high-resolution transmission electron microscopy (HRTEM), our ITO NWs have the tendency to grow vertically outw...

Studies of polymeric ternary composite thin films incorporating inorganic materials are of immense importance for current technological applications. Polyimide (PI) composite thin films incorporating indium tin oxide (ITO) and poly (vinlylidene fluoride) (PVDF) at various weight ratios were processed using an in situ generation approach with the spin coating unit. The resultant product was oxid...

A thin buffer layer of cadmium oxide (CdO) was used to enhance the optical and electrical properties of indium tin oxide (ITO) films prepared by an electron-beam evaporation technique. The effects of the thickness and heat treatment of the CdO layer on the structural, optical and electrical properties of ITO films were carried out. It was found that the CdO layer with a thickness of 25 nm resul...
