Electrically tunable organic bioelectronics for spatial and temporal manipulation of neuron-like pheochromocytoma (PC-12) cells

► The PC-12 cells can be spatially and temporally manipulated. ► Alternating PEDOT and rGO striped microelectrode arrays were fabricated. ► The outgrowth of bipolar neurites was found to align along the electrodes. ► The electrical stimulation was used to convert the surface property of PEDOT.
