22_01/2010Bioinspired Photonic Crystals: Diamond-Structured Titania Photonic-Bandgap Crystals from Biological Templates (Adv. Mater. 1/2010)

The striking coloration of the weevil Lamprocyphus augustus is the result of exoskeleton photonic structures with a diamond-based lattice. Michael Bartl and co-workers report on p. 107 on the development of a sol–gel templating method to convert these unique biopolymeric structures into high-dielectric replicas. Theoretical, structural, and optical studies reveal these bioderived photonic crystals possess a complete bandgap at visible frequencies – the basis for novel optical phenomena based on light localization.
