Abstract

Highly biocompatible advanced materials with excellent electroactivity are increasingly meaningful to biointerfaces and the development of biomedicine. Herein, bacterial cellulose/poly(3,4-ethylene dioxythiophene)/graphene oxide (BC/PEDOT/GO) composite nanofibers were synthesized through the in situ interfacial polymerization of PEDOT with the doping of GO. The abundant free carboxyl and hydroxy groups offer the BC/PEDOT/GO film active functional groups for surface modification. We demonstrate the use of this composite nanofiber for the electrical stimulation of PC12 neural cells as this resultant nanofiber scaffold could closely mimic the structure of the native extracellular matrix (ECM) with a promoting cell orientation and differentiation after electrical stimulation of PC12 cells. It is expected that this biocompatible BC/PEDOT/GO material will find potential applications in biological and regenerative medicine.

Keywords: bacterial cellulose nanofibers; biointerface; electrical stimulus; graphene oxide; poly(3,4-ethylenedioxythiophene).
