Purdue University researchers developed a technique using sugar filaments spun like cotton candy and coated with a polymer to create a scaffold of tiny synthetic tubes that might serve as conduits to regenerate nerves severed in accidents or damaged by disease. In this image, taken with a scanning electron microscope and artificially colored, the sugar strands are shown in yellow and the polymer coating in blue.
