Abstract: This article explores the possibilities of using Sb doped SnO₂ thin films as potential electrode substrates for biosensors. Two series of electrodes were modified with electrogenerated functionalised polymeric films. The polymers investigated were biotinylated poly(ruthenium pyrrole) and poly(pyrrole benzophenone). AFM studies show polymer morphologies depending on the nature and roughness of the substrates.

Keywords: modified electrode, metallic oxide film, surface roughness, biosensors
