▎ 摘　　要

Nanomaterials and nanotechnology is in forefront of materials research. Minimal attention is given to the potential participation of these materials in cell metabolism. Here we review recent efforts to understanding how carbon nanomaterials participate on cell metabolism. First, the introduction to the materials science of graphene, carbon nanotubes and metallic nanoparticles is give. Second, different mechanisms of participation of these materials on the cell metabolism are discussed and elucidated.
