An ambitious professor Shu Yang, from the University of Pennsylvania recently developed a material, which imitates the water-resistant and iridescent properties of the wings of butterfly, with the help of holographic lithography.

Yang used holographic lithography to recreate the reflective properties of the butterfly wing. Using a laser to make a 3D cross-linked pattern a structure is created that mimics the structure that makes butterfly wings water-resistant. This coating can be applied to anythin from electrical components to fabric to paper making them "<i>hydrophobic</i>".
