一般描述

羟基磷灰石（HA）属于钙磷灰石家族， 在结构和化学成分上与天然骨相似。它可以 通过化学沉淀法、水热法、静电纺丝法和 自传播燃烧法等多种方法制备。由于其生物活性和生物相容性， 它被广泛用作骨再生的植入材料、 药物载体和基因传递系统。

应用

纳米羟基磷灰石颗粒具有缓慢的原位生物降解、良好的骨导电性和骨诱导能力，可用于制备骨组织工程材料。

聚(4-苯乙烯磺酸钠)修饰的羟基磷灰石纳米颗粒可作为万古霉素的药物载体。羟基磷灰石纳米颗粒可控制支架植入体内后抗生素的释放。

多孔羟基磷灰石微球对重金属具有较高的吸附能力，可用于重金属污染水体的处理。

特点和优势

  • 生物活性和生物相容性
  • 机械强度好
  • 多孔结构
  • 骨传导和骨整合特性

Biodegradable polymer/bioceramic composite scaffolds can overcome the limitations of conventional ceramic bone substitutes such as brittleness and difficulty in shaping. However, conventional methods for fabricating polymer/bioceramic composite scaffolds often use organic solvents (e.g., the solvent casting and particulate leaching (SC/PL)
