Figure 2

(a,b) Prototype of the overall relaxed and bended tubular microelectrode, respectively. (c,d) The electrode sites of the thin film microelectrode and the tubular microelectrode, respectively. The golden and black sites were bare gold and PEDOT/PSS modified electrode sites, respectively. (e,f) Enlarged view of single electrode site morphology of bare gold and PEDOT/PSS modified electrode sites, respectively. (g,h) finite element simulation results of current streamline distribution for small and large reference electrode configuration, respectively. (i) Immunofluorescent image of PC-12 cells cultured for 7 days with the addition of neural growth factor (NGF).
