Figure 4: The ability of C. elegans to resistance acute oxidative stress is statistically decreased by exposure to coated-MNP. (A) Survival curves; (B) mean survival. Each graph is the representative average of 3 different trials, n=100 worms per group. Error bars represent the standard deviation of the average.
