Considerations of the thermodynamics, kinetics, and mass transport will be discussed for both direct and mediated bioelectrochemistry, along with how nanomaterials and polymers can be used to enhance electrochemical properties. Finally, the talk will end with a discussion of the applications of bioelectrochemistry.
