Figure 6. In vivo electrochemical characterization of the PEDOT/hydrogel/BDNF coating.
Each graph represents a single animal; Animals A & B (top) received PEDOT/hydrogel/BDNF-soaked implants and Animals C & D (bottom) received bare implants. EIS data was collected prior to implantation (day 0) and at regular intervals over a 6-month period. At 81 days post-implantation, the impedances for Animal D exceeded the limitations of our system, becoming non-measurable, and no further data could be collected for this animal.
