Molecular organization of the nanoscale surface structures of the dragonfly Hemianax papuensis wing epicuticle.

The molecular organization of the epicuticle (the outermost layer) of insect wings is vital in the formation of the nanoscale surface patterns that are responsible for bestowing remarkable functional properties. Using a combination of spectroscopic and chromatographic techniques, including Synchrotr...
