Replicated - Butterfly Wings On A Nano Scale

Researchers have developed a technique to replicate biological structures, such as butterfly wings, except on a nano scale and the resulting biomaterial could also be used to make optically active structures, such as optical diffusers for solar panels, they say. Insects' colors and their iridescence (the ability to change colors depending on the angle) or their ability to appear metallic are determined by tiny nano-sized photonic structures (1 nanometer = 10-9 m) which can be found in their cuticle. Scientists have focused on these biostructures to develop devices with light emitting properties.  Their work was presented in the journal Bioinspiration&Biomimetics. read more
