Tiny plastic fingers, each with a diameter 1/500th of a human hair, cradle a tiny green sphere

I love this photo. I saw it on +Rich Pollett's profile and wondered what it was, and where to find the high-resolution file:


Tiny plastic fibers, each with a diameter of 250 nm, spontaneously wrapped around a plastic ball when they were immersed in an evaporating liquid. First reported in Science (Pokroy et al., Science 2009), the finding demonstrates a new way of controlling the self-assembly of polymer hairs. The image was produced with a scanning electronic microscope and was digitally enhanced for color.
