Neurite outgrowth of dorsal root ganglia neurons is enhanced on aligned nanofibrous biopolymer scaffold with carbon nanotube coating

► We coated CNTs on the surface of PLCL nanofiber scaffolds. ► Outgrowth of DRG neurons was in parallel to the alignment of nanofiber. ► CNTs-coated nanofiber scaffolds improved the neurite outgrowth of DRG neurons. ► FAK protein expression was significantly enhanced by the CNTs coating.
