What is it about?
Resveratrol is a fluorescent bioactive compound with antioxidant activity. In this work, its effectiveness as a dispersing agent for graphene in aqueous solutions was assessed. The interaction between graphene and resveratrol was investigated via absorbance, fluorescence and Raman measurements. Dispersions were prepared via bath sonication, followed by probe ultrasonication and centrifugation. The the two last stages have little effect on the dispersion quality.

Why is it important?
he results of this study could open new perspectives for using natural products like resveratrol as biocompatible and efficient dispersing agents of G to be used in numerous applications, especially in biomedicine.
Perspectives
A simple, quick and environmentally friendly approach to prepare high-quality graphene dispersions in both aqueous and organic media has been described that could be extended to other bioactive compounds.
