Icariin-Loaded TiO₂ Nanotubes for Regulation of the Bioactivity of Bone Marrow Cells

Figure 1

FE-SEM images of the surfaces of Ti specimens before and after anodization. (a) Pure Ti, (b) NT arrays after anodization at 10 V (NT₁₀), and (c) NT arrays after anodization at 30 V (NT₃₀). TiO₂ NTs with different diameters can be fabricated with ethylene glycol, and the resulting diameter is positively related to the voltage of anodic oxidation.
