Electrochemical oxidation of hollow sporopollenin particles immobilised on an electrode surface is investigated in aqueous acidic solution. Redox activity is demonstrated to occur via a mixture of 2e(-)-2H(+) and 2e(-)-1H(+) processes, likely due to the oxidation of conjugated phenolics embedded within the surface-shell of the polymer particles. Charge transport over the surface is suggested to be fast based on comparison with an approximate physicochemical model. (C) 2010 Elsevier B.V. All rights reserved.
