Microscopic images of collagen-based ECTs containing different concentrations of MWCNTs-Py-OH or MWCNT-Py-COOH. The tissue sections were stained with Masson’s trichrome stain and examined with a light compound microscope. (A) Control ECT; (B) 0.025% MWCNTs-Py-OH; (C) 0.050% MWCNTs-Py-OH; (D) 0.100% MWCNTs-Py-OH; (E) 0.025% MWCNTs-Py-COOH; (F) 0.050% MWCNTs-Py-COOH; (G) 0.100% MWCNTs-Py-COOH. Scale bar 100 µm.
