Viability of hDPSCs exposed to graphene-based nanomaterials at the concentrations of 25, 50, 100, 250, 500, and 1000 μg/mL determined by the MTT assay after 24 hours. The results are given in percent compared to the untreated control group. Results are the (bars) of three independent experiments each carried out in triplicate. value < 0.05.
