Table 3.

NTA measurements of TiO₂ NPs dispersed in DI water, 0.05% BSA-water and supplemented RPMI 1640 media. Data are shown as mean, mode, and 90% distribution (D90) values ± standard error of the mean (SEM). In addition, 0.05% BSA-dH₂O and media controls at 2.5 × 10⁻² mg/mL equivalent dilutions data are included as controls.
