Abstract
Carbon nanomaterials, such as carbon nanotubes and graphene, have recently been explored as artificial bioscaffolds due to their exceptional mechanical, electrical, and thermal properties. In particular, three-dimensional graphene foam (3D-GrF) has been speculated to possess the fundamental cues that drive stem cell differentiation and guide cell growth. 3D-GrF creates a biocompatible, biomimetic micro-environment that promotes cell proliferation and differentiation, specifically into osteogenic or chondrogenic cell lines. Here, we report the mechanical properties of tissue grown within the 3D-GrF scaffold using unconfined static and dynamic compression. This work has quantified the tangent compressive modulus, dynamic modulus, percent stress relaxation, and phase shift in tissue grown in a 3D-GrF scaffold in order to provide an evaluation of the feasibility of using graphene bioscaffolds in cartilage repair and regeneration.
