Physicochemical characterization of TiO2 nanoparticles: (A) Transmission electron micrograph showing the primary size of TiO2 NPs and their agglomeration due to their high reactivity. (B) Crystalline phase identification of anatase by electron diffraction obtained in TEM. (C) Average diameter and polydispersity index (PDI) of TiO2 NPs after dispersion in water (0 h, control), 24 h after stabilization and incubated with medium culture (TiO2 NPs in BSA DMEM 10% FBS). TEM micrographs of TiO2 NPs in distilled water and in medium culture are shown demonstrating an alteration in NPs morphology. Data represent mean ± standard deviation (SD), n = 30 in each condition. #P < 0.05 vs control and *P < 0.05 vs control.
