a High porosity zone of MPS-HA composite structure: (left hand side) top view taken from scanning electron microscopy (inset shows the magnified view); (right hand side) EDS mapping corresponding to the fibrous morphology confirms the nucleation and formation of HA within/over the MPS substrate. b Low porosity zone of MPS-HA composite structure: (left hand side) top view taken from scanning electron microscopy (inset shows the magnified view with the spherical morphology); (right hand side) EDS mapping corresponding to the spherical morphology confirms pore size and type the nucleation and formation of typical HA within/over the MPS substrate
