Study on Photodynamic Therapy for HL60 Cells Inactivation by Visible Light-induced Fe-doped Nano-TiO_2 under Magnetic Field

摘要

Fe-doped TiO_2 was prepared by a homogenous precipitation method and characterized by XRD, UV-Vis DRS. The structure and the optical properties of nano-TiO_2 with different Fe doping content were studied, as well as the effect and the possible mechanics of different intensity of TiO_2 particles, Fe-doped nano-TiO_2 particles on the activity of HL60 leukemic cells. The influence on the activity of cells exposures in light compared with un-exposure also be analysed. As the photo sensitizers, TiO_2 and Fe-doped TiO_2 particles eliminated tumor cell using photodynamic therapy(PDT)under magnetic field.
