Fig. 3: Biocompatibility and Imaging Quality Assessment of FPE-PEDOT.

a In vitro cell viability test results using double staining with Hoechst and Propidium iodide. Scale bars, 50 µm. b Immunohistochemistry analysis of brain tissue sections post-implantation of FPE-PEDOT and Pt-black films. Scale bars, 50 µm. c Comparison of imaging quality between platinum and FPE-PEDOT, with the latter showing no autofluorescence and clear cell imaging. Scale bars, 100 µm. The data shown in Fig. 3a-c representative of three independent experiments with similar results.
