Release date- 10092013 - A new study has revealed that the stunning iridescent wings of the tropical blue Morpho butterfly could expand the range of innovative technologies.
Scientific lessons learnt from these butterflies have already inspired designs of new displays, fabrics and cosmetics.
Now research by the
Tiny tree-like nanostructures on the scales of Morpho wings are known to be responsible for the butterfly's brilliant metallic blue iridescence. The study, published in the journal PNAS, found that vapour molecules adhere differently to the tops of these structures than to the bottom. This selective response to vapour molecules is the key to the range of possible bio-inspired technological applications.
Although not essential for butterfly survival, this unique property of selective gas adsorption is a by-product of the process of butterfly wing scale development.
