NAC prevented oxidative stress and preserved cell viability reduction caused by pure and Al-doped ZnO nanoparticles.
(A) ROS, (B) GSH, (C) TSH and (D) cell viability. Data represented are mean ± SD of three identical experiments made in triplicate. *Statistically significant difference as compared to controls (p < 0.05). #Significant inhibitory effect of NAC on oxidative stress and cytotoxicity (p < 0.05).
