What is it about?
The use of environmentally friendly methods via covalent and non-covalent routes to exfoliate and prepare surface-functionalized GO nanosheets with tannic acid, a biological macromolecule with antioxidant activity. This improves its processability in aqueous media and biocompatibility.

Why is it important?
This work not only highlights the great potential of TA for both exfoliation and surface functionalization of GO, but also extends its applications in biomedicine and for the development of green nanocomposites.
Perspectives
This study paves the way towards the synthesis of green graphene derivatives to be applied in the biomedical field, as sensor devices or for the development of ecological nanocomposites.
