Abstract: An electrochemical reactor block including at least two pellets cut out of a flexible conductive film including chains of a linear polymer, carbon nanotubes being bound to each of the chains by pi-pi interaction, a catalyst agent selected from the group including enzymes, metal catalysts, macrocyclic catalysts, and redox mediators being trapped between the pellets.

Abstract: The invention relates to nanoparticles, preferably metal oxides, at least partially coated on the surface by a silylated polymer, and functionalised by at least one molecule of an oxidation-reduction mediating agent, characterised in that the immobilisation of said molecule(s) of said mediating agent on the surface of said nanoparticles is enabled by non-covalent bonds, preferable ?-? type interactions, established between ethylenic, acetylenic and/or aromatic patterns, respectively present in the region of said silylated polymer and said molecule(s) of the oxidation-reduction mediating agent.
