A highly selective dopamine sensor was fabricated by doping polypyrrole with a sulfonated beta-cyclodextnn This composite material enabled the selective sensing of dopamine in the presence of a large excess of ascorbic acid and prevented the regeneration of dopamine through the homogeneous catalytic reaction of the ascorbate anion with the dopamine-o-quinone A single redox wave corresponding to the oxidation of dopamine was observed in dopamine/ascorbate mixtures giving a truly selective dopamine sensor The limit of detection was measured as 3 2 x 10(-6) M for dopamine (C) 2010 Elsevier B V All rights reserved
