Figure 6.
X-ray diffraction patterns of the mineralized pore surfaces of the PLGA scaffolds after 16-day incubation in simulated body fluids of different ionic activity product. Apatite formed from low IP SBF (0.75 × SBF) showed sharp peaks, indicating high crystallinity, whereas comparatively broader peaks were exhibited in the apatites formed from high IP SBF (2.00 × SBF) indicating low crystallinity.
