a Microscopic images of L929 cells at 24 h seeded on various PEDOT: PSS films. Bright-field microscopy images (first row) and fluorescent microscopy images of live/dead staining (second row). b Cell viability was assessed using MTT assay at 24 h. *P < 0.05, **P < 0.01, and ***P < 0.001 (n = 3). Statistical analysis was performed using Tukey’s test, with significance compared to the control group, and non-significant differences excluded. c H&E staining slices of hindlimb (first column) and heart musucles (second column) with different PEDOT: PSS. d Fluorescent images immunochemically labeled by 4’,6-diamidino-2-phenylindole (DAPI), the biomarker neurofilament (NF) and inflammatory biomarker (ED1) of different PEDOT: PSS films.
