Graphene Nanoparticles
Graphene-based nanomaterials can be biocompatible with or toxic to biological cells. The response of living cells to these nanomaterials is highly dependent on the number of layers, lateral size, purity, dose, surface chemistry, and hydrophilicity. The surface chemistry of graphene nanomaterials is very different because different strategies have been used for their synthesis and different molecules or polymers are available for surface functionalization.
