(C) Confocal image showing cell distribution on the PCL/HA/MWCNTs scaffold. Reproduced with permission from Ref. [140].Copyright 2019 Elsevier B.V. (D) The cross sections of bone tissue regeneration at the bone defect for PCL or PCL/MWCNTs scaffolds treated groups after 60 days and 120 days. Reproduced with permission from Ref. [142].

(E) Schematic illustration of the mechanism of PEDOT-PDA-mSF patch in accelerated diabetic wound healing. 1) PDA promoted the cell adhesion and migration due to its cell/tissue affinity. (2) The conductive patch facilitated bioelectricity transmission. 3) The patch alleviated inflammation and 4) relieved oxidative stress. Reproduced with permission from Ref. [143].
