A facile synthesis of anatase TiO2 nanoparticles using functionalized PEO-based materials as polymeric stabilizers |
| 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. In this study, the results for synthesis and the characterization of new water-soluble anatase TiO2 nanoparticles stabilized by PEO-based polymers are reported. Nano-sized TiO2 was prepared by a conventional process such as in aqueous media or organic solvents. New water-soluble TiO2 nanoparticles using both PEO-folate conjugate and PEO-b-PMAc as stabilizers exhibiting anatase crystalline structures were successfully synthesized in ethanol.The resulting nanocrystalline TiO2 showed anatase crystal structure (10nm 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). |
