The damage of bovine serum albumin (BSA) under the ultrasound irradiation in the presence of titanium dioxide (TiO2) was studied by means of ultraviolet-visible (UV-Vis) and fluorescence (FL) spectroscopy, and the catalytic performance of rutile and anatase TiO2 was compared. Furthermore, the effects of several factors including the irradiation time, the TiO2 addition, solution acidity, ultrasound power and ionic strength on the damage of BSA molecule were also discussed. The results showed that the catalytic performance of rutile TiO2 was obviously better than that of anatase TiO2. It was found that under a certain condition, the damage degree of BSA molecule became more serious with the increase of the irradiation time and ultrasound power, while the influences of the TiO, addition, ionic strength and solution acidity were complicated.
