Impressive find. However, given that the toxicity of graphene is not well understood[1], shouldn't there be significant concern for now about using graphene in processes which involve contact with food products? It's easy to envision a scenario in which a microscopic chunk of the stuff breaks off and ends up in the air or your stomach. The article only hints at this, where it mentions "mechanical stability."
