Butterfly Wing Shimmer Done With 3-D Crystals
June 15, 2010
Those shimmering flashes of light seen on butterfly wings are not done with pigments. They’re done with tiny, geometric crystals called gyroids stacked in 3-D patterns, scientists have found. They are so effective at concentrating color, the scientists want to imitate the trick. “A precise characterization of color-producing biological nanostructures is critical to […]
