TL;DR: The results proved the intensification of oxidative stress after GO injection, which was confirmed by increased enzyme activity, and the organism seems to cope with this stress, especially in the first 24h after injection.

TL;DR: The results showed that short-term exposure to graphene oxide in food causes an increase in the parameters of oxidative stress of the tested insects, and induces damage to the DNA at a level of approximately 35% and contributes to a disturbance in the stages of the cell cycle and cause an increase of apoptosis.

TL;DR: The aim of the study was to describe the ultrastructure of the gut epithelium in Acheta domesticus after exposure to different concentrations of ND, and a positive relationship between the ND concentration in food and the degree of damage to the structure of epithelial cells was observed.

TL;DR: Analysis of DNA damage performed after fourteen weeks using the comet assay revealed DNA instabilities in the insects, especially the ones that had been exposed to the higher doses of ND, which may suggest that the toxicity of ND is concentration dependent.

TL;DR: The results showed that long-term exposure to GO caused a significant decrease in the reproductive capabilities of the animals and the next generation of A. domesticus had a lower cell vitality compared to their parental generation, suggesting that graphene oxide can cause multigenerational harmful effects.
