Study on Structure and Properties of Crystalline Hydroxyapatite obtained from Biological and Synthetic Sources

In this preset work bio-sourced hydroxyapatite (HAP) from waste egg shells and synthetic hydroxyapatite from calcium hydroxide were synthesized. A comparative analysis and characterization were done using XRD, FTIR, green density, porosity, cytotoxicity and hemolysis studies. It was found that both types of materials are almost similar in their properties and highly biocompatible. The biologically derived egg shell hydroxyapatite can be an ideal substitute for synthetically derived hydroxyapatite.
