Functionalization of Graphene Oxide Nanosheets Can Reduce Their Cytotoxicity to Dental Pulp Stem Cells

LDH leakage from hDPSCs after incubation with different concentrations of the graphene-based nanomaterials (25, 50, 100, 250, 500, and 1000 μg/mL) for 24 h. The LDH results are given in the activity unit/mL. Results are the (bars) of three independent experiments each carried out in triplicate. Although exposure to nGO-CS leads to lower LDH leakage than nGO, nGO-COOH had no significant effect on LDH leakage in hDPSCs. value < 0.05.
