The Morpho Sulkowsky butterfly uses its flashy iridescent wings to
attract attention, but humans could use those wings in applications
ranging from homeland security to medical imaging. Researchers at the
General Electric Global Research Center attached carbon nanotubes to
real Morpho butterfly wings, and used the resulting structures as
infrared (IR) light sensors, which have applications in medicine,
science, environmental sustainability and the military, to name a few.
