制备了一种聚-(L-乳酸)(PLLA)和碳纳米管(CNTs)的复合材料,并利用原子力显微镜(AFM)和接触角检测对材料的表面形貌和性质进行了表征.初步研究了复合材料的生物相容性以及CNTs对细胞亲和性的影响.结果表明,复合材料对于鼠3T3成纤维细胞和Oct-1成骨细胞具有良好的生物相容性.CNTs的加入对细胞亲和性有很大影响,对细胞的贴附有一定的抑制作用.
A composite of poly (L-lactic acid) (PLLA) and carbon nanotubes (CNTs) was prepared and its surface morphology and properties were characterized by atomic force microscopy (AFM) and contact angle measurement The biocompatibility of the composites and the effect of CNTs on the cell affinity were studied.The results showed that the composites have good biocompatibility to the 3T3 fibroblasts and the Oct-1 osteoblasts.The addition of CNTs to the cells And sex have a great impact on cell adhesion has a certain inhibitory effect.
