Figure 9From: Optimized dispersion of nanoparticles for biological in vitro and in vivo studiesStability of TiO 2 (rutile) dispersion. TiO2 (rutile) dispersions were prepared in distilled water at a concentration of 0.02 mg/ml with (closed circles) or without (open circles) addition of HSA before giving concentrated PBS to the dispersion. The average hydrodynamic diameter of the particles was measured at different time points for up to one week. The experiments were carried out in triplicates (*, p < 0.05, dispersions with vs. without HSA at the same time point).Back to article page
