The structure and morphology of the samples were further confirmed by the TEM and TEM images of the prepared nano-hydroxyapatite, as shown in Figure 6. The transmission electron microscopic analysis confirms the presence of the spherical shape morphology of the prepared hydroxyapatite nanoparticle with the particle size of around 60 to 70 nm (Figure 7). The particle size is also found to be in agreement with the report results of Ferraz et al. (2004).
