We propose nanostructured indium tin oxide (ITO) electrodes as a promising platform due to their good electrical conductivity, transparency to visible wavelengths and high surface-to-volume ratio. The nanostructured electrodes were fabricated by electron beam evaporation, and electrochemical techniques were used to quantify more than a 40% increase in electrochemical surface area compared to thin ITO films. The electrodes were derivatized with organosilanes and coated with a molecule providing redox activity. Indeed, an increase in detectability of more than 400% was observed with respect to thin films, indicating the potential viability of nanostructured ITO-based electrochemical biosensors.4 p.application/pdfengcc-by (c) Pruna Morales, Raquel et al., 2017http://creativecommons.org/licenses/by/3.0/esDetectors químicsÒxidsSiliconesEspectroscòpia d'infraroigs per transformada de FourierChemical detectorsOxidesSiliconesFourier transform infrared spectroscopyinfo:eu-repo/semantics/article6782072020-03-13info:eu-repo/semantics/openAccess
