Morpho sulkowskyi


"The surface of Morpho wings are essentially covered in nanoscale solar cells, honeycomb-like structures that trap light, much like a fibre-optic cable, and convert it to heat to keep the insect warm in cold environments. Miyako deposited carbon nanotubes onto the butterfly wings, where they self-assembled into nanostructures that mimic the Morpho's multilayered hexagonal microstructures.

The resulting hybrid gives the term "bio-tech" new meaning: the natural pattern provided by the wings creates a large light-receiving surface area, and the physical properties of nanocarbons produce heat through vibrational energy. Lab tests confirmed that the nanotubes generate heat when struck with a laser, and Miyako says the composite material heats faster than its two components would by themselves."
