FIELD: medicine.
SUBSTANCE: there is described method of obtaining of calcium phosphate nanoparticles, stabilised by salt matrix by interaction of components, first of which contains metal cation, and second contains anion. According to invention as the first component applied is water-soluble calcium salt, and as the second component, soluble orthophosphate, nanoparticles of water non-soluble calcium phosphate being formed, and salt matrix being formed from soluble by-product. Content of calcium phosphate nanoparticles in powder composite "oxide nanoparticles/salt matrix" constitutes 65-82 wt %.
EFFECT: method is aimed at creation of effective nanotechnologies, in order to prevent degradation, that is, aggregations of oxide nanoparticles of calcium phosphates.
