Abstract/OtherAbstract:
Phototoxicity of titanium dioxide modified with platinum(IV)-chloride complexes, [TiO2/PtCl4], irradiated with visible light was tested on murine macrophage cell line (RAW 264.7) in vitro. Presence of antioxidants such as alpha-tocopherol or beta-carotene during photodynamic treatment significantly increased cells viability. Our results indicate that observed cell death induced by [TiO2/PtCl4] was due to photogeneration of reactive species.
