Cytotoxicity in BEAS-2B and SAEC after 24 and 72 h of exposure to each MWCNT material. a. BEAS-2B, 24 h. b. BEAS-2B, 72 h. c. SAEC, 24 h. d. SAEC, 72 h. MWCNT-7 white, MWCNT-HT gray, and MWCNT-ND black bars. V2O5 was used as a positive control, 0.316 μg/mL in BEAS-2B and 3.16 μg/mL in SAEC cell. * indicates significantly different from control, p < 0.05. ¥ indicates significantly different from other MWCNT materials at same dose, p < 0.05; ± SD
