Fig. 1From: Zirconia Nanoparticles-Induced Toxic Effects in Osteoblast-Like 3T3-E1 CellsCharacterizations of the TiO2 and ZrO2 NPs. TiO2 (a) and ZrO2 (b) NP morphology and size were detected using TEM. (c) The co-culture situation of 3T3 cells and nanomaterials was observed after TiO2 and ZrO2 NP treatment concentrations of 10, 50, and 100 μg/mL. (d) The TEM results were obtained after TiO2 and ZrO2 NP treatment for 1 hBack to article page
