In this work, the influence of graphene nanoribbons (GNs), graphene nanoplatelets (GNPls), multi-walled carbon nanotubes (MWCNTs) and graphene oxide (GO) as a modifier on the properties of screen-printed carbon electrodes towards electrochemical determination of riboflavin (VB2) is investigated. Additionally, ionic liquid (IL, 1-Butyl-2,3-dimethylimidazolium tetra fluoroborate), iron(II) phthalocyanine (FePc) and Nafion were added into the modifier suspensions and further tested for their electro-catalytic effect. Their performance as modifier is compared to unmodified screen-printed carbon electrodes (SPCE). Unmodified screen-printed electrodes are printed in laboratory onto the ceramic substrate using carbon ink. Modified electrodes are prepared by drop-casting modifier suspension onto the active …
