Nanostructured Mesoporous Silicas for Bone Tissue Regeneration
Figure 4
Bioactive in vitro study corresponding to an ordered mesoporous glass
with 3D bicontinuous cubic structure and composition. (Inset) schematic representation of 3D cubic pore arrangement. (a)
Variation of calcium content and pH values of SBF after soaking the materials
during different periods. (b) HRTEM study corresponding to the surface of
mesoporous glasses after 4 hours soaked in SBF. Low magnification image
indicates the needle-like crystals formation on the surface of mesoporous
glass. Higher magnification and FT transform showing the (002), (211), and
(112) reflections corresponding to d-spacings of 0.34, 0.28, and 0.27 nm of an
apatite phase.
