Surface Charge of Hydroxyapatite and Bone Mineral

Abstract:

Article Preview

The surface charge of calcium phosphates in Simulated Body Fluid (SBF) may be one of the factors associated with the adhesion of cells and proteins, processes that are related with osteogenesis. For calcium phosphates in SBF, surface charge varies with solution pH due to the adsorption of positive ions and to the reactions that occur at the solid/biological fluid interface. In this work, the variation of the density of protons adsorbed and the surface charge as a function of pH were determined for Hydroxyapatite, CaHPO4, and Bone Mineral.
