Abstract :
Hydroxyapatite (HA, Ca₁₀(PO₄)₆(OH)₂) constitutes the major inorganic hard tissues, such as bone and teeth. Various substitutions in the apatite structure have been developed for a wide range of biomedical applications, such as the bone repair and tissue regenerations. Dual ionic substitutions are improving the mechanical and biological properties of hydroxyapatite (HA). Substitution of trace elements, such as Sr, Mg, Zn ions into the structure of calcium phosphates is the subject of widespread investigation. Our studies deals with the synthesis of copper/zinc co-substituted HA nanoparticles (Ca/Cu/Zn/HA) by precipitation method, which enhance biocompatibility, bioactivity and mechanical properties. Furthermore, co-substituted HAp obtained from synthetic and biological precursors, along with their influence on the bone regeneration process, has been discussed. The synthesized composite material was characterized by FTIR, XRD, SEM, EDAX, and antimicrobial studies. The as-developed composite material can act as a potential role in biomedical applications.
