Abstract Transparent conducting electrodes (TCEs) require high transparency and low sheet resistance for applications in photovoltaics, photodetectors, flat panel displays, touch screen devices imagers. Indium tin oxide (ITO), or other transparent conductive oxides, have typically been used, provide a baseline ( R S ) vs. T relationship. However, ITO is relatively expensive (due to limited abundance of Indium), brittle, unstable, inflexible; moreover, drops rapidly wavelengths above 1000 nm....

A label-free electrochemical impedance spectroscopy (EIS) aptasensor for rapid detection (<35 min) of interferon-gamma (IFN-γ) was fabricated by immobilizing a RNA aptamer capture probe (ACP), selective to IFN-γ, on gold interdigitated electrode array (Au IDE). The ACP modified with thiol group at the 5' terminal end and subsequently co-immobilized 1,6-hexanedithiol (HDT) 6-mercapto-1-hexanolphosphate (MCH) surface through thiol-gold interactions. This ACP/HDT-MCH ternary monolayer...
