Synthesis of Hydroxyapatite from natural sources for biomedical applications – An overview

The research hypothesis is mainly focused on the synthesis of hydroxyapatite from biowaste materials. Different methods were used for the synthesis of hydroxyapatite. The synthesized hydroxyapatite was characterized by different techniques such as FTIR, XRD, SEM, EDAX, and microbial studies and whether this material suitable for biomedical applications or not. From these studies, the following parameter was found out like Ca/P ratio, crystallinity, particle sizes, and morphology of the synthesized particles. In this review paper we gave collective information regarding what are the methods used for the synthesise of hydroxyapatite and how to characterize the sample with different techniques and which will be useful for the researcher who has to do the research in the same field. With this idea they can easily synthesize the expecting bioceramic from waste material and how it would be applicable for the biomedical applications本研究的核心研究假设主要围绕以生物废料为原料合成羟基磷灰石（hydroxyapatite）展开。本次研究采用多种方法合成羟基磷灰石，并通过傅里叶变换红外光谱（FTIR）、X射线衍射（XRD）、扫描电子显微镜（SEM）、能谱分析（EDAX）及微生物学实验对所制备的羟基磷灰石进行表征，同时验证该材料是否适用于生物医学应用。通过上述实验，可获取合成颗粒的钙磷比、结晶度、粒径及形貌等关键参数。本综述系统梳理了羟基磷灰石的合成路径、样品表征所用的各类技术手段，可为该领域的科研人员提供极具价值的参考依据。借助本综述的相关内容，相关研究者可轻松利用废料合成预期的生物陶瓷，并明晰其在生物医学领域的应用方向。
