Understanding the properties and development of complex morphological traits may spark advances in the biomimetic design of new self-assembling multifunctional materials. Thus, we are using cutting-edge techniques to I identify previously unexplored chemical and physical properties of, and II synthetically mimic, color-producing nanostructures built from keratin and melanin in bird feathers. For I we are testing four properties of optical nanostructures 1 Refractive index and chemistry. 2 Tensile strength. 3 Thermoregulation. 4 Hydrophobicity. For part II we use biomimetic approaches to elucidate the mechanisms by which these nanostructures self assemble. We have succeeded in organizing melanin particles into simple nanostructures that are responsive to environmental changes, and are proceeding with experiments using blends and modified particle types. The results of this research will enhance our understanding of the multifunctionality of nanostructured traits and identify new means and natural materials for their production.
