A cyclodextrin-modified pyrrole monomer (Py-CD) was synthesized and used both as an aq. surfactant for the stabilization of aq. reduced graphene oxide (RGO) dispersion and as an electropolymerizable unit to generate a RGO-polypyrrole composite electrode. This nanocomposite was used in combination with amphiphilic pyrrole deriv. for the entrapment of tyrosinase, an enzyme catalyzing the oxidn. of phenols and diphenols. Compared to glassy carbon electrodes, these nanostructured electrodes exhibit enhanced electroactive surface area and electrochem. properties and achieve higher performances towards catechol and dopamine biosensing.
