Subtle Butterfly Wing Differences Could Inspire New Materials

Facebook Twitter LinkedIn Email Comments
HONG KONG, July 19, 2013 — Subtle differences in the small crystal structures responsible for the varied patterns of color in butterfly wings could lead to new material coatings that change color by design. Butterfly wings can do remarkable things with light, but much research still needs to be done for humans to replicate the wings’ light-manipulating properties. “It was very exciting to see how nature can create a nanostructure that’s not easy to replicate by humans,” said Kok Wai Cheah, a physicist at Hong Kong Baptist University, who has been working with colleagues to...Read full article
