Elaboration de Nouveaux Matériaux d'Electrodes obtenus par Autoassemblage de Polyélectrolytes, Nanoparticules et Biomolécules : Etudes physico-chimiques et applications.

Abstract : The thesis describes the physico-chemical characterization and the electroanalytical applications of new nanocomposite materials, built onto electrode surfaces, in the form of multilayer thin films, by electrostatic self-assembly of polyelectrolytes (PE), enzymes and gold nanoparticles (NP).
The growth of these films was followed in situ by UV-Visible spectroscopy and microgravimetry. The electrochemistry allowed quantifying the electron transfer process, the films permability and the electroenzymatical kinetics. The kinetic and structural modelization allowed establishing structure-properties relationships.
The glucose oxidase and the polyphenol oxidase have been assembled onto gold and glassy carbon electrodes with the polydiallyldimethylammonium and the chitosane. The assembly of NP with osmium complex or viologen based redox PE leads to nanocomposite films where the electronic conduction properties have been characterized and applied to the development of transducers.
