Differential neural cell adhesion and neurite outgrowth on carbon nanotube and graphene reinforced polymeric scaffolds.

Carbon nanomaterials, such as graphene nanoplatelets (GNPs) and multiwalled carbon nanotubes (MWCNTs) are potential candidates in a large number of biomedical applications. The present study investigates the effect of the difference in morphology of these materials on neural cell regeneration on a biodegradable scaffold. Electrical conductivities of all the hybrid scaffolds are found to be in between that of MWCNT/chitosan scaffold (highest-conductivity) and GNP/chitosan scaffold (lowest-conductivity).
