Metallic nickel nanoparticles and their effect on the embryonic development of the sea urchin Paracentrotus lividus

Optical images of the sea urchin before and after exposure to different concentration of nickel nanoparticles, to find malformations of sea urchin , the images were measured in micron size nickel nanoaprticles were characterised by high resolution transmission electron microscopy to determine the crystalinity and size of nanoparticles.
