A linear gradient in hydroxylapatite mineral content was achieved with both 10SBF and m10SBF. The ratio of the number of Ca atoms per unit volume to the combined numbers of Ca and C atoms, as measured with EDX, increased linearly along the length of the scaffold’s mineral gradient (measurements are shown for 4 10SBF samples and 3 m10SBF samples).
