Functionalization protects the cells against oxidative stress. DCFDA assay analysis for measuring the ROS following exposure of HEK 293 cells to functionalized MWCNTs (MWCNT-COOH & MWCNT-NH2) in comparison to pristine MWCNTs. The bars represent reactive oxygen species (ROS) generation. Y-axis represents percentage increase in ROS with respect to MWCNT concentration (x-axis). Analysis of variance (p < 0.05). Where, p < 0.05 (*) and p < 0.01 (**).
