The synthesis of calcium hydroxyapatite in a slightly modified SBF fluid by self-assembly on the surfaces of SiO(2) thin films was investigated in this study. The mechanism of their nucleation on the surface of silica thin films of various depths was particullarly investigated by using AFM. The analysis of the obtained phases after different times of sample ageing in modified SBF was determined using the FTIR-ATR method. The thicknesses of the film were investigated over the mass changes of the samples. The corresponding corrections related to the total pore volume inside of them were included in the final results of their thicknesses.
