The article reports that the researchers at Georgia Tech University, Atlanta, Georgia, have used iridescent butterfly wings as a mould to make alumina photonic crystals. According to researcher Zhonq Lin Wang, if one examines the wing scale, one can see all of the intricate micron-scale and nanometre-scale features that determine the optical properties. The moulded alumina, converted from amorphous to polyalumina to give it additional strength, also reflects bluish light.
