What is it about?
Advances in tissue engineering rely on the interactions of cells with their extracellular matrix proteins. The polymer sulfonated polystyrene (SPS), used as a scaffold for tissue development, has previously been found to stimulate protein adsorption. We found that the gold reduced graphene oxide increased protein adhesion to the SPS surfaces, while both the gold and plain reduced graphene oxide induced dental pulp stem cell differentiation into bone cells.

Why is it important?
Our research shows exciting promise for creating synthetically produced polymer scaffolds to be used for the repair of biological tissue and the development of artificial organs for transplant.
Perspectives
It was a pleasure working on this project with the two first authors, who were high school students during the time they conducted this research.
