Butterfly images take flight
Researchers at Oak Ridge National Laboratory, US, and North Carolina State University, US, have used scanning probe microscopy (SPM) to look at the structure of a butterfly's wing. They found that acoustic imaging enabled them to look at the internal structure of the wing in fine detail.
Acoustic imaging revealed details of around 5 nm. The researchers say this is on the length scale of individual chitin fibrils forming the wing.
