제목 Titanium dioxide nanoparticlesstabilized by PEO-based functionalized materials
초록 Recently photodynamic therapy (PDT) as an alternative treatment for cancer therapy has received a great attention in the biomedical field. For the photodynamic therapy, a photosensitizer with TiO2, gold or ZnO as a photocatalyst should be used. TiO2 nanoparticles have been used in the solar cell field because of strong oxidizing power and long term thermodynamic stability. Especially, titanium dioxide has been found to produce the reactive oxygen species (ROS) under the UV range of electromagnetic radiation. In this repeat, the generated electron-hole pair with radical is major conceptual paradigm for the cancer therapy. In this study, TiO₂ nanoparticles were prepared by using PEO-b-PMAc as a polymeric stabilizer. The resulting nanocrystalline TiO₂ showed anatase crystal structure (10 nm or less) on the basis of the characterization XRD, TGA, TEM, and ED-pattern analysis. Its photo-catalytic activity was evaluated on the degradation of methylene blue (MB).
