Fig. 3. Neural marker expression of differentiated SH-SY5Y cells on control, CNT network and graphene film. (A) Western blotting images (B) SMI31 (C) MAP2 (D) SOX2 (E) GFAP and (F) NeuN expression relative to GAPDH of differentiated SH-SY5Y cells on the control, CNT network and graphene film. (G) Immunofluorescence images. BF means “bright field”. Error bars represent the standard deviation of three replicates. * for p < 0.05, ** for p < 0.01. Scale bar represents 100 μm.
