Effect of ZNGs on nematode lifespan, body size and fertility rate. Kaplan–Mèier survival plots of worms treated or not with ZNGs starting from a adult or b larval stages; n = 60 for single experiments. The abbreviation ‘ns’ indicates that results are not significant in comparison with control (log-rank test). c Average embryos production per worm of animals exposed to ZNGs with respect to untreated nematodes. Bars represent the mean of three independent experiments. d Effect of ZnO NR-decorated GNPs on C. elegans larval development. Worms were grown in the presence of E. coli OP50 supplemented or not with ZNGs and their length was measured from head to tail at the indicated time points. Statistical analysis of c and d was evaluated by one-way ANOVA method with the Bonferroni post-test (ns not significant)
