SAEC were treated with varying concentrations of DM, ND-MWCNT, or MWCNT-7 for a 24 h period. CellTiter 96® Aqueous One Solution was added 4 h prior to end of exposure and absorbance was measured at 490 nm. Results indicate that MWCNT-7 induces a significant increase in cell proliferation at 0.12 μg/ml compared to DM and ND-MWCNT at 1.2 μg/ml and decrease at 120 μg/ml compared to DM. * p ≤ 0.05.
