Abstract
ZnO/Dens composite were prepared with nano-sized ZnO and porcine dens powders by mechanical mixing, liquid boiling, ultrasonic dispersion and heat-treated at 500°C for 50 min. The samples were characterized by X-ray diffraction (XRD) and its sonocatalytic activity was evaluated by the damage of bovine serum albumin (BSA). Furthermore, the effects of ultrasonic irradiation time, ZnO/Dens composite amount, solution acidity and ionic strength on the sonocatalytic damage of BSA were evaluated. The results show that the damage degree of BSA aggravated with the increase of ultrasonic irradiation time, ZnO/Dens composite amount and ionic strength, but weakened with the increase of solution acidity. In addition, the damage site to BSA molecules was analyzed by synchronous fluorescence spectra and the results exhibited that the damage site was mainly at tryptophan (Trp) residue. This study should be helpful to drive sonocatalytic method to treat tumors in clinic application.
