Abstract
Background: Cerium ions promote osteoclastogenesis and activate bone metabolism, while cerium oxide nanoparticles exhibit potent anti-inflammatory properties, making them promising for biomedical applications.
Objective: The purpose of this study was to develop and evaluate a synthesis method for sustained-release cerium-ion bioceramics containing apatite. Substituted apatite was found to be an effective biomaterial.
Methods: Cerium-containing chlorapatite was synthesized using a mechanochemical method employing dicalcium phosphate, cerium chloride heptahydrate, and calcium hydroxide as raw materials. The synthesized samples were characterized using X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy, energy-dispersive X-ray spectroscopy, and Raman spectroscopy.
Results: Cerium chlorapatite was successfully synthesized in the 10.1% and 20.1% samples. However, at Ce concentrations higher than 30.2%, the samples consisted of three or more phases, indicating the instability of a single phase.
Conclusion: The method used in this study was found to be more efficient and cost-effective than the precipitation method for producing substituted apatite and calcium phosphate-based biomaterials. This research contributes to the development of sustained-release cerium-ion bioceramics with potential applications in the field of biomedicine.
背景：铈离子可促进破骨细胞生成并激活骨代谢，而氧化铈纳米粒子则具有强大的抗炎特性，使其在生物医学领域具有广阔的应用前景：本研究旨在开发和评估一种含有磷灰石的持续释放铈离子生物陶瓷的合成方法。研究发现，替代磷灰石是一种有效的生物材料：方法：以磷酸二钙、七水合氯化铈和氢氧化钙为原料，采用机械化学方法合成了含铈的磷灰石。使用 X 射线衍射 (XRD)、傅立叶变换红外光谱 (FTIR)、扫描电子显微镜、能量色散 X 射线光谱和拉曼光谱对合成样品进行了表征：在 10.1% 和 20.1% 的样品中成功合成了氯磷灰石铈。然而，当 Ce 浓度高于 30.2%时，样品由三相或多相组成，表明单相不稳定：本研究采用的方法比沉淀法生产替代磷灰石和磷酸钙基生物材料更有效、更经济。这项研究有助于开发在生物医学领域具有潜在应用价值的缓释铈离子生物陶瓷。
