Figure 1. Schematic illustration of the preparation process for BC/PPy gradient conductive membranes and the electrotaxis chamber setup. The BC/PPy gradient conductive membranes were fabricated via a kinetically controlled reaction using a peristaltic pump. Subsequently, PC12 cells were seeded onto the membranes and subjected to electrical stimulation within an electrostimulation cell culture device. BC: Bacterial cellulose; PPy: polypyrrole; p-TSA: para-methylbenzenesulfonic acid; PC12: pheochromocytoma.
