A new understanding of the physics of conductive materials has been uncovered by scientists observing the unusual movement of electrons in graphene.
More research is need to determine whether graphene is harmful to our bodies if ingested. Graphene is a form of carbon, a naturally-occuring material and one that is found inside the human body. However, very small doses of graphene could potentially be harmful, although no harmful effects have been recorded.
This animation looks at how harmful graphene could be and how it could affect us when being used in biomedicine or graphene production.
