纳米材料由于其独特的理化性质和颗粒尺寸,可以模拟自然界中的纳米级细胞外基质成分,也可直接穿过细胞膜,传递生物活性物质,这些特质使其成为组织工程研究的理想材料。
纳米材料可应用于组织工程的领域包括骨组织、神经组织、动脉组织、皮肤、牙齿等。
碳纳米管良好的强度、弹性和抗疲劳性使其成为骨组织工程支架的理想材料。优异的导电性及形状尺寸与神经突类似的特点也使碳纳米管成为神经组织工程中十分受欢迎的材料。
碳纳米管的直径和表面化学修饰与其生物效应密切相关, 长度大于20µm的碳纳米管不能被巨噬细胞吞噬降解,容易引发炎症反应。相较于单壁碳纳米管,多壁碳纳米管(MWCNT)的细胞毒性更低,且MWCNT具有硬度大、质量轻等特点,在组织修复工程中应用更为广泛。
