(Guo and Mei, 2014) Graphene, graphene oxide and reduced graphene oxide cause toxic effects to living cells. Low dosage may be safe and serve as enhancers of cell proliferation. Its toxicological effects varies on sizes, shapes, surfaces, and the fabrication. For example, different production methods affect the amount of oxygen bound to the surface which can be correlated with their toxicity towards cells and other living systems. GUO, X. & MEI, N. 2014. Assessment of the toxic potential of graphene family nanomaterials. J Food Drug Anal, 22, 105-15.
