Abstract
In this work, we present the development and the characterization of a simple sensing platform based on graphite screen-printed electrodes, which were properly modified with a conducting copolymer nanofilm. The platform was realized by the simultaneous electropolymerization of aniline and anthranilic acid monomers in equal proportion onto the graphite electrodic surface. The obtained copolymer was fully characterized through cyclic voltammetry by using [Ru(NH3)6]2+/3+ reversible couple as redox probe. The electroactive surface area was calculated by means of the Randles-Sevcik equation and compared with those of the individual polymers (polyaniline and polyanthranilic acid). The selected platform could be then used for different applications, e.g. as a scaffold to immobilize a biological receptor.
