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.

Electric power supply devices which convert biological energy, such as chemical energy of metabolism or mechanical energy of periodic movements, into electrical energy.
Organic polymeric materials which can be broken down by naturally occurring processes. This includes plastics created from bio-based or petrochemical-based materials.
A member of the c-ets family of transcription factors that is preferentially expressed in cells of hematopoietic lineages and vascular endothelial cells. It was originally identified as a protein that provides a retroviral integration site for integration of FRIEND MURINE LEUKEMIA VIRUS.
An integration host factor that was originally identified as a bacterial protein required for the integration of bacteriophage Q beta (ALLOLEVIVIRUS). Its cellular function may be to regulate mRNA stability and processing in that it binds tightly to poly(A) RNA and interferes with ribosome binding.
Materials fabricated by BIOMIMETICS techniques, i.e., based on natural processes found in biological systems.
A biomaterial is defined as a substance that has been engineered to take a form which, alone or as part of a complex system, is used to direct, by control of interactions with components of living systems, the course of any therapeutic or diagnostic proc...
Within medicine, nutrition (the study of food and the effect of its components on the body) has many different roles. Appropriate nutrition can help prevent certain diseases, or treat others. In critically ill patients, artificial feeding by tubes need t...
