Electrochemical determination of hydrogen peroxide production by isolated mitochondria: A novel nanocomposite carbon-maghemite nanoparticle electrode
Original language description
A simple carbon paste electrode modified with novel maghemite (gama-Fe2O3) nanoparticles, characterized by a mean diameter of about 10 nm and specific surface properties (called surface active maghemite nanoparticles, SAMNs) has been developed. The electrode is able to catalyze the electro-reduction of hydrogen peroxide at low applied potentials (?0.1 V vs. SCE). In order to improve the electrocatalytic properties of the modified electrode and to protect electrode surface from fouling due to the presence of biological materials, a surfactant, namely cetyltrimethylammonium bromide, was introduced, as monomolecular layer, on electrode surface. At ?0.1 V, the sensitivity of the modified nanocomposite electrode was 58 nA mýM?1 cm?2, with a detection limitof 2.78 mýM, in the 0.01-1.5 mM H2O2 concentration range, revealing to be one of the most sensitive electrodes described in literature. The resulting electrode was used to determine native monoamine oxidase activity on intact mitochondria
