Metal-free fluorinated graphene shows no signs of toxicity in cell culture tests

This image from a high-resolution transmission electron microscope shows one of Rice University’s #graphene-based MRI contrast agents, nanoparticles measuring about 10-nanometers in diameter that are so thin that they are difficult to distinguish.
