Abstract

Dielectrophoresis is used to align carbon nanotubes (CNTs) within gelatin methacrylate (GelMA) hydrogels in a facile and rapid manner. Aligned GelMA-CNT hydrogels show higher electrical properties compared with pristine and randomly distributed CNTs in GelMA hydrogels. The muscle cells cultured on these materials demonstrate higher maturation compared with cells cultured on pristine and randomly distributed CNTs in GelMA hydrogels.

摘要

介电泳用于以简单快速的方式在明胶甲基丙烯酸酯（GelMA）水凝胶内排列碳纳米管（CNT）。与 GelMA 水凝胶中的原始 CNT 和随机分布的 CNT 相比，排列的 GelMA-CNT 水凝胶表现出更高的电性能。与在 GelMA 水凝胶中的原始 CNT 和随机分布的 CNT 上培养的细胞相比，在这些材料上培养的肌肉细胞表现出更高的成熟度。
