Hydroxyapatite synthesis and characterization from marine sources: A comparative study.

Background: Hydroxyapatite (HAP) is a biocompatible material widely used in biomedical applications. Recent studies have explored various marine sources for HAP synthesis, demonstrating its potential for diverse applications.

Objective: This study aims to compare the characteristics of hydroxyapatite synthesized from sea shells and fish bones, specifically from the shells of (orange mud crab) and bones of (fourfinger threadfin).
