Electrochemical impedance spectroscopy. a–d), electrochemical impedance spectrum for PEDOT nanotube sites (PEDOT NTs) and uncoated sites (control) before implantation (a), immediately after implantation (b), day 8 after implantation (c), day 49 after implantation (d). e), impedance magnitude at 1 kHz over time after surgery. f–q), Nyquist plots of uncoated (control) and PEDOT nanotube sites (PEDOT NTs) after implantation in day 0 (f, g), day 3 (h, i), day 6 (j, k), day 13 (l, m), day 29 (n, o), and day 49 (p, q). The data in the graphs was averaged between the 20 uncoated sites and 20 PEDOT nanotube sites. The bars denote standard error of the data set on a given day (n = 20). Day 0 measurements were taken immediately after surgery.
