| Abstract
| - Nanocrystalline calcium phosphate based inorganic, hydroxyapatite (HAp), was synthesized using thedodecyl phosphate micelle system. The surfactant concentration during synthesis played an important roleon the final properties of these HAp nanoparticles. A surfactant concentration close to the critical micelleconcentration produced the nanoparticles with the highest surface area, with porous less agglomeratedmorphology. Compacts made of these nanopowders showed between 97 and 98% theoretical density ofphase-pure HAp and promoted cell−material interaction when cytotoxicity tests were performed.
