To enhance the surface bioactivity of titanium (Ti) prostheses, an electroactive polyvinylidene fluoride (PVDF) film was prepared on a Ti substrate to provide a mimetic of the electrical microenvironment, which facilitated the performance of cell functions. The results of cell proliferation and differentiation assays indicated that polarization of the PVDF-Ti (PTi) altered its surface charge, thus inducing adhesion, proliferation and osteogenic differentiation of cells. The polarized PVDF-Ti (PPTi) may therefore find applications in bone regeneration.
为提高钛(Ti)假体的表面生物活性,在Ti基底上制备了一种电活性聚偏二氟乙烯(PVDF)薄膜,以模拟电微环境,促进细胞功能的发挥。细胞增殖和分化测定结果表明,PVDF-Ti(PTi)的极化改变了其表面电荷,从而诱导细胞的粘附、增殖和成骨分化。因此,极化的PVDF-Ti(PPTi)可能在骨再生中得到应用。
