Аннотация: In this work, the influence of small amounts of ruthenium (III) ions on the morphology, phase composition and structure of the products formed under the conditions of hydroxyapatite (HAP) synthesis was studied by the methods of electron microscopy (including high resolution), energy-dispersive and X-ray phase analysis, . It has been shown that the introduction of doping ruthenium(III) ions into the reaction medium at various stages of HAP formation affects the degree of aggregation of primary HAP-Ru nanoparticles. In the case of the introduction of Ru at the final stage of HAP formation, the formation of individual thread-like HAP-Ru nanoparticles is observed, but the formation of the own ruthenium phase does not occur. Ru(III) ions are distributed predominantly evenly over the surface of the nanoparticles. The cocrystallization method for creating composites of HAP with ruthenium radionuclides is promising for the development of new radiopharmaceuticals
