These images have been created using a colour scanning electron microscope (SEM) by the award-winning Eye of Science, comprised of snapper Oliver Meckes and biologist Nicole Ottawa. For a decade the pair, based in Reutlingen in the south of Germany, worked with an old SEM they saved from the scrapheap, but for the last five years they have used a £250,000 FEI Quanta Series Field Emission SEM.
