Description

The  Bioelectrocatalysis Group of the ICP was started by Prof. Victor M. Fernández in the mid 80s. Since then the main research goals of the group have been the study and characterization of redox enzymes and their interfaces with electroactive surfaces, as well as the applications of bioelectrodes.

Research lines

  • Structure/function relationship studies of redox metalloenzymes
  • Development of strategies for oriented and stable immobilization of redox enzymes on electrodes for applications in biofuel cells, biosensors, hydrogen production or cofactor regeneration.
  • Development and characterization of nano-structured electrodes and the study of the integration of nano-materials (gold/magnetic nanoparticles, carbon nanotubes, graphene) with biocatalysts.
  • Development of photocatalysts and photoelectrocatalysts based on redox enzymes immobilized on inorganic semiconductors.
  • Reconstitution of membrane enzymes on electrodes modified with biomimetic membranes.
