本发明属于骨修复生物材料和药物缓释载体制备技术领域，具体是一种制备介孔羟基磷灰石纳米颗粒/二氧化钛纳米管阵列新型复合材料的方法。
背景技术
在最近的几十年里，纳米材料在生物医学研究、疾病诊断和治疗方面的应用吸引了越来越多人的兴趣。然而，传统的诊断和治疗药物(如药物或基因)在临床的应用受限于其稳定性差，副作用的几率高,缺乏药物动力学研究，快速清除、高剂量和无特异性靶向。纳米粒子被认为是有用的加载诊断和治疗药物的纳米载体。在过去几十年里，纳米材料已被用于治疗癌症、伤口和细菌感染。它们提高了药物的疗效，减少了副作用，许多纳米材料如石墨烯，氧化物、碳纳米管、金属氧化物、水凝胶、树枝状大分子、脂质体等常常用于药物传递。尽管纳米载体可以保护显像剂免于酶的催化降解，但纳米载体的毒性成了其生物医学应用的一个问题。在过去的几年里，无机纳米材料因其优异的稳定性、高的生物分子负载量和表面易于接合生物分子，被广泛的应用于纳米载体。
不同纳米结构的TiO2材料的制备和应用的研究得到了长足的发展。人们采用不同方法制备不同的纳米结构，包括纳米粒子、纳米棒、纳米纤维、纳米层和纳米管。其中，TiO2纳米管阵列具有许多优点，是吸附药物的良好载体。通过阳极氧化法在钛金属表面构建的高度有序的TiO2纳米管阵列，具有制备工艺相对简单、阵列高度有序、管径可控、纳米管与基底结合更加牢固等优点。其本身纳米级多孔形貌，适于多种细胞黏附和生长。因此TiO2纳米管有序阵列作为内置物表面修饰方法具有良好的应用前景。
羟基磷灰石(Ca10(PO4)6(OH)2或HA)具有良好的生物相容性，独特的机械性能，生物活性，以及和活骨组织形成化学键的优秀能力，并且无毒性、非炎症性质。人们研究它的各种形态和表面性质，将其作为药物载体负载药物甚至作为眼科内置物使用。但较低的比表面积限制了它在许多条件下的进一步应用。介孔羟基磷灰石能够在一定程度上克服这些缺点，并对骨头细胞和组织有好的生物相容性和生物活性。Negar等（Int. J. Pharm.,2016(509): 159-167）以介孔羟基磷灰石为涂层，修饰在超顺磁Fe3O4纳米粒子表面作为药物传输载体。
