Recent studies have shown that the electrochemical oxidation of purine nucleobases (adenine and geaoine) at graphite electrodes is strongly dependent on the orientation of graphene sheets. their size and mutual distribution on the electrode surface. Edges and defects of graphene sheets affect the kinetics of oxidation processes, basal planes support the adsorption processes The aim of this study is to determine how model carbon nanomaterials including graphene, single-walled or multi-wailed carbon nanotubes. carbon nanofibres and mesoporous graphene affect the electrochemical oxidation or purine nuclebases on screen-printed carbon electrodes modified by these nanostructures in solution without and in the presence of copper.
