Abstract:

磷酸钙作为生物体硬组织中主要的无机成分,具有良好的生物相容性、生物活性及生物可降解性,广泛应用于骨组织与牙齿修复和替换、药物输运和控制释放、基因转染及诊断成像等生物医学领域。人工合成磷酸钙材料的组成、结构、尺寸、形貌和结晶度等特性均与材料的制备方法有关,且材料的这些特性对其应用起到决定性作用。因此,发展不同的方法制备出具有特定组成、结构、尺寸、形貌、结晶度和性能的磷酸钙纳米材料对其应用至关重要。本文综述近年来在磷酸钙纳米材料的制备、表征、性能和应用研究方面所取得的最新进展,讨论室温制备法、溶剂热/水热合成法、微波辅助快速合成法、静电纺丝法及含磷生物分子磷源合成法等制备方法,分析磷酸钙纳米材料的性能及其在药物装载和可控释放、蛋白质吸附及释放、生物成像等领域的应用,展望磷酸钙纳米材料研究领域的发展趋势。
