Název v původním jazyce

In vitro anti-microbial activity of titanium dioxide nanoparticles

Popis výsledku v původním jazyce

Titanium dioxide (TiO2) has wide applications in various fields including cosmetics, pharmaceuticals, textile and waste water treatment due to its many properties such as photocatalytic activity and stability. In the present study, the synthesis of TiO2 nanoparticles (NPs) was achieved by hydrolysis condensation method where a liquid phase of TiO2 was obtained. TiO2 NPs were characterized by X-ray Diffraction (XRD), UV-Visible spectrometry, Scanning Electron Microscopy (SEM). The photocatalytic activity of TiO2 NPs was examined by monitoring the degradation of methylene blue dye in water when treated with TiO2 NPs. TiO2 NPs were found to be highly photocatalytic achieving 90% degradation ratio after 80 min. In this study antimicrobial activity test was carried out for TiO2 NPs against selected Gram-positive/negative bacteria both in the presence or absence of UV exposure. TiO2 NPs expressed a significant effect on microbial growth only on high concentrations exceeding 1 mg/ml.
