Morphology of normal human skin fibroblast cells (CRL2522, ATCC) on (a–c) the tissue culture polystyrene plate (TCPP), (d–f) polyurethane (PU) film (g–i) PU film containing 0.01 % wt % MWNT (PU-MWNT01), (j-l) PU film containing 0.04 % wt % MWNT (PU-MWNT04), m–o PU film containing 0.08 % wt % MWNT (PU-MWNT08) after cultured for 24, 48 and 72 h. p Cell proliferation of normal human skin cells growing on the TCPP, PU film, PU-MWNT01, PU-MWNT04, and PU-MWNT08 films after incubated for 24, 48 and 72 h. Error bars indicate standard deviation (n = 3)
