To demonstrate the design, fabrication and testing of conformable conducting biomaterials that encourage cell alignment.
MATERIALS & METHODS: Thin conducting composite biomaterials based on multilayer films of poly(3.4-ethylenedioxythiophene) derivatives, chitosan and gelatin were prepared in a layer-by-layer fashion. Fibroblasts were observed with fluorescence microscopy and their alignment (relative to the dipping direction and direction of electrical current passed through the films) was determined using ImageJ.
Fibroblasts adhered to and proliferated on the films. Fibroblasts aligned with the dipping direction used during film preparation and this was enhanced by a DC current.
We report the preparation of conducting polymer-based films that enhance the alignment of fibroblasts on their surface which is an important feature of a variety of tissues.
展示可促进细胞排列的适形导电生物材料的设计、制造和测试。
基于聚(3,4-亚乙基二氧噻吩)衍生物、壳聚糖和明胶的多层膜制备了薄导电复合生物材料,采用逐层方式进行。用荧光显微镜观察成纤维细胞,并使用ImageJ确定其排列方向(相对于膜制备过程中的浸渍方向和通过膜的电流方向)。
成纤维细胞在膜上黏附并增殖。成纤维细胞与膜制备过程中使用的浸渍方向对齐,并且直流电流可增强这种对齐效果。
我们报道了基于导电聚合物的膜的制备,该膜可增强成纤维细胞在其表面的排列,这是多种组织的一个重要特征。
