Abstract:
Traditional design and manufacture method is less likely to duplicate the expected elaborate structures and functions, which seriously hinders the discovery of new phenomenon and the establishment of new mechanism between structures and functions. The chemical constituents within the organism can be replaced with the desired functional constituents by using the multi-level, multi-dimensional and multi-scale intrinsic bio-structure as template, through physical and chemical process. This innovative material, which endows the desired function while maintains the original bio-structure at the same time, is named morpho-genetic material. This manuscript presents the design, manufacture, characterization and mechanism of optical function morpho-genetic material, illustrates by two typical examples：metal-semiconductor functional wings enhanced infrared absorption and photothermal conversion, metal wing surface enhanced Raman scattering. The research thought and synthesis method mentioned here offer a new solution for the synthesis of multi-level fine structure. Furthermore, it provides a foresight and theoretical support for proposal of the novel material.
