Fig. 3: In vitro electrochemical characterization of PEDOT-SNP film doped with Glu and GABA on Pt pad chemical sites with a geometric area of 16,000 µm2.

a CV characterization of PEDOT-SNP(Glu) film and PEDOT-SNP(GABA) film. b EIS characterizations of PEDOT-SNP(Glu) film and PEDOT-SNP(GABA) film. c In vitro drug release profile determination of Glu and GABA from chemical electrodes. Release profile of Glu released from PEDOT-SNP(Glu) film and GABA released from PEDOT-SNP(GABA) film. Three neural probes were used for each of GABA and Glu groups
