Pure and Strontium Doped Nano Hydroxyapatite: New Approach for Bone Implant and Drug Delivery System

Hydroxyapatite, $(Ca10(PO4)6(OH)2–Hap),$ an excellent inorganic biomaterial, find various applications. The chemical composition of Hap is similar to that of the inorganic matrix of human bone and dental enamel. It is also used in drug delivery system and coating of bone implant. In the present study, pure nano Hap and Strontium doped nano‐Hap (Sr‐Hap) with different concentrations were synthesized by surfactant mediated approach. The samples were characterized by EDAX, XRD and TEM. The hemolytic properties were also studied and it proved that all the samples were non‐hemolytic.
