Summary of "Biocatalytic protein-based materials for integration into energy devices."

There is a current need to fabricate new biobased functional materials. Bottom-up approaches to assemble simple molecular units have shown promise for biomaterial fabrication due to their tunability and versatility to incorporate functionalities. Here, we demonstrate the fabrication of catalytic protein thin films by the entrapment of catalase into protein films composed of a scaffolding protein. Extensive structural, and functional characterization of the films evidences the structural integrity, order, stability, catalytic activity, and reusability of the biocatalytic materials. Finally, we couple these functional biomaterials with piezoelectric discs to fabricate a second generation of bio-inorganic generators. These devices are capable to produce electricity from renewable fuels through catalase-driven gas production that mechanically stimulate the piezoelectric material.
