Graphene is a 2D material, like a sheet of paper. A carbon nanotube is more of a 1D material, like a pencil. Carbon nanotubes have (extremely) sharp points. A single wall carbon nanotube has a diameter of ±1.4nm. That is a lot smaller than the size of a cell. The danger of nanotubes in living organisms is that they can puncture cells. A graphene sheet cannot do that. That’s why nanotubes are potentially more harmful than graphene. |
