CONSIDERATION REGARDING THE USE OF TIO2 DOPED NANOPARTICLES IN MEDICINE

In present work, nanocrystalline powders of TiO2 undoped and doped with Pt and Au ions respectively were synthesized. The synthesis was performed under hydrothermal conditions, at a temperature of 493 K for 5h. Obtained nanocrystalline powders were characterized by X-ray powder diffraction (XRD) and transmission electron microscopy (TEM). The citotoxic effect of TiO2 nanoparticles undoped and doped with Pt and Au ions respectively on human eritroleukemia tumoral cell line (K562) was investigated.
