Preparation and characterization of calcium phosphate nanoparticles

In this work, CaP nanoparticles were prepared by wet chemical precipitation using three different approaches and were characterised and quantified in terms of their composition. Different precipitating, ageing and drying temperatures were applied and affected HA to TCP ratio. Sintering induced formation of large agglomerates and affected the relative composition, specifically, increased concentrations of TCP as proved by SEM, FTIR and XRD. Different reactants also affected chemical final product composition. Contacts with fibroblasts and osteoblasts revealed better adhesion to sintered substrates.
