Graphene oxide biodegrades with help of human enzymes        

Graphene Flagship researchers show how graphene oxide suspended in water biodegrades in a reaction catalysed by a human enzyme, with the effectiveness of the breakdown dependent on the colloidal stability of the suspension. ​The study should guide the development of graphene-based biomedical applications.
