Polydispersity index of TiO 2 (rutile) in dispersions with different HSA concentrations. TiO2 (rutile) dispersed in distilled water at a concentration of 0.02 mg/ml was sonicated and HSA at concentrations ranging from 0.0015 to 15 mg/ml were given to the dispersion prior to addition of concentrated PBS. Polydispersity index (PdI) of the particles was measured. The experiments were carried out in triplicates (*, p < 0.05 vs. dispersion with 0.0015 mg/ml HSA).
