Graphene and other related materials have varying properties with different biological effects, so understanding the potential Health and Environmental risks of this group has been at the centre of Graphene Flagship activities since the beginning.
Currently the largest EU-funded Future Emerging Technologies (FET) Flagship, the Graphene Flagship is currently studying the toxicology of this group of materials using classification based on the lateral dimensions, number of layers and carbon-to-oxygen ratio. This way they can focus on potential interactions of graphene with key organs including the immune system, skin, lungs, cardiovascular system, gastrointestinal system, central nervous system, reproductive system, as well as a range of organisms including bacteria, algae, plants, invertebrates and vertebrates in various ecosystems.
