Traditional materials science engineering produces materials (for example, medium-carbon steels depicted in the bright- and dark-field TEM images), that have been successfully used over the last century. Molecular biology focuses on structure–function relations in bio- macromolecules In molecular biomimetics, a marriage of the physical and biological fields, hybrid materials could potentially be assembled from the molecular level using the recognition properties of proteins under the premise that inorganic surface-specific polypeptides could be used as binding agents to control the organization and specific functions of materials.
