Synthesis and charaterization of TiO2 nanoparticles and its cytotoxcity in CHO cell line

Abstract

TiO₂ nanoparticles as photocatalyst were synthesized by sol-gel route involving, and it is efficiently characterized by techniques, such as XRD, TEM, FTIR and DLS. The cytotoxicity of Titanium dioxide was evaluated on CHO cell line. The cytotoxicity of TiO₂ is dependent on the dose and it shows gradual increase in the percentage of dead cell after 24 h of TiO₂ exposure. The cytotoxicity due to TiO₂ increases with the increase in the concentration of TiO₂ nanoparticles from 1 to 75 µg/ml.
