Conductive Polymers as Bioelectronic Materials

摘要

Fibroblast L929 and myoblast C2C12 cells of mouse connective tissue origin were sown on the surface of conductive polymer films [polypyrrole (PPy) and poly(3,4-ethylenedioxythiophene) (PEDOT)] in a cell culture medium, and the proliferative process of these cells was observed. Without changing form, fibroblast L929 and myoblast C2C12 cells were observed to proliferate similarly to cells cultured in commercially available dishes and to maintain compatibility. It is inferred that the two conductive polymers used in this study, PPy and PEDOT films, maintain the secretion functions of cells cultured on their surfaces. Therefore, PPy- and PEDOT-coated electrodes are possibly usable as nerve stimulation electrodes with bio-compatibility, because they have been effective in cell culturing.
