[1] Double doping nanoparticles of hydroxyapatite / M. R. Gafurov, G. V. Mamin, S. B. Orlinskii et al. // Proceedings of XV International Scientific School "Actual Problems of Magnetic Resonance and its Application". — Kazan Federal University Kazan, Russia, 2012. — P. 60–62. Synthetic hydroxyapatite (HAP) Са10(РО4)6(ОН)2 – widespread material that used in medicine for treatment of damaged bone tissue due to chemical and stage similarity with inorganic components of bone tissue. For enhancement of efficiency of bioresorbable implants as substitutes of bone tissue it is possible to use a material bases on carbonized hydroxyapatite Ca10-xNax(PO4)6-x(СO3)x(OH)2, in which РО4 group partially replaced by СO3 group. It is more precisely reproduce the structure of bone in comparison with not modified hydroxyapatite. The CW X-band EPR spectra of carbonized and doped with manganese hydroxyapatite were measured and interpreted, their spectroscopic and relaxation characteristics were obtained. Measurements showed that the concentration of complexes NO32- is equal in the samples of carbonated hydroxyapatite and HAP dopes with manganese. The study of samples of hydroxyapatite doped with manganese ions showed higher probability of complex formation of manganese ions and NO3 groups within the crystal structure of hydroxyapatite. The results can be useful for the modernization of the synthesis of nanocrystalline hydroxyapatite.
