Conductive Graphene/Carbon Nanofiber Composite Scaffold, its use for neural tissue engineering and a method of preparation thereof

摘要

Porous electrically conductive graphene/carbon nanofiber bio-scaffolds can be fabricated having a Youngs modulus and electrical conductivity that both match typical values for brain tissue. Such scaffolds have been tested and found to provide proved differentiation of stem cells into functional neural cells relative to conventional scaffolds. In preferred embodiments, neural cell differentiation in conductive graphene/carbon nanofiber scaffolds is promoted by an applied electrical stimulus.
