Figure 1From: Optimized dispersion of nanoparticles for biological in vitro and in vivo studiesEffect of intensity of sonication on TiO 2 (rutile) particle size. TiO2 (rutile) dispersed in distilled water at a concentration of 0.02 mg/ml was sonicated with different specific energies, and the average of the hydrodynamic diameter of the particles was measured. The experiments were carried out in triplicates (*, p < 0.05).Back to article page
