Fig. 10From: Prospects on the nano-plastic particles internalization and induction of cellular response in human keratinocytesThe effect of a single-dose exposure to lethal and sub-lethal concentrations of NPs on the proliferation of HaCaT cells. a The NPs induced growth inhibition in the HaCat cells exposed to PENPs (50 and 100 µg mL−1), PSNPs (50 and 100 µg mL−1), NPs-1 (50 and 100 µg mL−1), NPs-2 (50 and 100 µg mL−1) and H2O2 (50 & 100 µM). b The relative difference in the proliferation index among the NPs.
