Background: Hydroxyapatite (HA) is a material with excellent bioactivity and chemical similarity to bone. It can be extracted from natural sources or fabricated synthetic sources.
Objective: To synthesize HA from domestic chicken eggshells and to characterize it using Fourier transform infrared (FTIR), X-ray powder diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy, and cell viability.
