  1. From Nature to Nanotech Biomimicry

  2. Blue Morpho Butterfly

  3. Iridescence Close-up of peacock feather • What does iridescence do in nature? • Attract mates or pollinators • Camouflage The iridescence in Blue Bedder flowers attracts pollinators What is iridescence? • Colors change depending on the angle at which you look at the surface • Different thicknesses, like with bubbles, can create iridescence. • Nano and micro features, as in the blue Morpho butterfly, also cause iridescence.

  4. Blue Morpho Butterfly Wing Scanning Electron Microscope image of the Blue Morpho butterfly showing repeating nanoscale features responsible for iridescence.

  5. Biomimicry of Iridescence Biomimicry of iridescence is used for security on currency and credit cards.

  6. Biomimicry of Iridescence Qualcomm has a new e-screen that mimics the iridescence of the blue Morpho butterfly. The screen gets brighter in sunlight.

  7. The Lotus Effect Lotus leaves and nasturtium leaves are self-cleaning due to nano and microscale structures and a waxy coating. Together these features create a superhydrophobic surface. Close-up of a nasturtium leaf, which exhibits the Lotus Effect, with a droplet of water

  8. The Lotus Effect

  9. Biomimicry of the Lotus Effect Nano-Tex fabric repels liquids and stains, also mimicking the Lotus Effect. Lotusan paint mimics the lotus plant’s self-cleaning properties.
