Using a graphene film provides a much high contrast revealing details.

Electron Microscopy images of bacteriophage T4 viruses. The left image was made using conventional carbon film, the right image using the single atom thin graphene layer. More details about the tail and the limbs of the viruses can be discerned. The black bar used for scale is 20 nanometers (0.00000002 meters).
