A protein-only redox film inspired by the architecture of bacterial electroactive biofilms has been developed. The film is formed using a rubredoxin–prion domain chimeric protein. The prion domains self-assemble into fibres that are decorated with rubredoxin. This results in highly organized films, able to transport electrons over several microns, and wire enzymes to electrodes.
