(a) Raman spectra of CAP powders composed of morphologically different particles (A–D), along with the denoted bands characteristic for three different CAP phases detected – monetite (CaHPO4), octacalcium phosphate (Ca8H2(PO4)6·5H2O), and hydroxyapatite (Ca10(PO4)6(OH)2); (b) Raman spectra of CAP comprising sample D per se and CAP comprising sample D loaded with CL. The encircled bands represent those derived from the organic phase. See the text for the detailed assignment of the vibrational bands.
