US researchers have shown how well graphene foam might be suited to tissue engineering and specifically as a scaffold for growing functional muscle tissue. Graphene foam is a 3D counterpart of the familiar 2D graphene carbon monolayer material. The team demonstrated that extracellular matrix proteins on graphene foam can boost the differential of stem cells to form muscles with the graphene foam itself acting as an electrode to stimulate the process. “We think we can build on these results to investigate the fundamental chemistry of life while advancing towards clinical applications,” David Estrada of Boise State University explains. “Graphene has just begun to flex its muscles in the bioengineering domain."
