Ellipsoidal Artificial Melanin Particles as Building Blocks for Biomimetic Structural Coloration.

Ellipsoidal Artificial Melanin Particles as Building Blocks for Biomimetic Structural Coloration. Inspired by the structural coloration of anisotropic materials in nature, we demonstrate the preparation of structural color materials by the assembly of anisotropic particles. Spherical artificial melanin particles consisting of a polystyrene core and polydopamine shell were stretched asymmetrically to form uniform-sized ellipsoidal particles with different aspect ratios. The aspect ratio and assembly method of the ellipsoidal particles influence the structural coloration, indicating that the particle shape is one of the important parameters for controlling the structural coloration. The discovery of a method to control the structural color using ellipsoidal particles is useful in basic research on structural colors in nature and provides flexibility in material design and extends the application range of structural color materials. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Langmuir Pubmed
