摘要:
生物材料的物理化学性质(如刚度、粗糙度、亲疏水性等)对细胞的粘附、增殖、迁移、分化、凋亡等一系列生命活动会产生重要的影响。此外,对材料进行图案化设计也是调控细胞生命活动的一种有效手段。采用软光刻的方法,以聚二甲基硅氧烷为印章,通过调节压力,获得图案较为规整的氧化石墨烯(GO)阵列。在优化的压力条件下,成功将GO阵列转移至硅、类金刚石膜、氧化铟锡玻璃三种刚性基底表面。利用基底材料与GO材料性能的差异,实现了对神经细胞(PC12)选择性粘附的有效调控。研究结果表明:与刚性基底相比,硬度较小且亲水的GO表面更能有效促进PC12细胞的选择性粘附和增殖。GO阵列表面越大,其表面粘附的细胞密度越大。
