Improving the Osteoblast Cell Adhesion on Electron Beam Controlled TiO₂ Nanotubes

Figure 2

FE-SEM images of synthesized TiO₂ nanotube under different anodization voltage. (a), (c), and (e) show surfaces of the nanotubes, and (b), (d), and (f) display the cross-sectional view of nanotubes fabricated at 15 V, 20 V, and 25 V, respectively.
