Butterfly wings are fragile biological nanostructures that derive their colour both from the structure of the scale cells on their surface and from pigment grains.
The image shows a AFM measurement of these optically invisible, fragile structure of a Butterfly wing.
The measurement was done in "Dynamic Force" operating mode.
This image shows the wing of a Peacock Butterfly.
It was measured with a Nanosurf easyScan DFM by Michael Drexel & Walter Freyn. Sample preparation Dr. Eckhard Hartmann (Augsburg University, Biology). Advanced Lab Course 20, Augsburg University, EKM, Experimentalphysik 6.
