In vivo intrinsic atomic interaction infer molecular eco-toxicity of industrial TiO nanoparticles via oxidative stress channelized steatosis and apoptosis in Paramecium caudatum.

The ecotoxicological effect of after-usage released TiO nanoparticles in aquatic resources has been a major concern owing to their production and utilization in different applications. Addressing the issue, this study investigates the detailed in vivo molecular toxicity of TiO nanoparticles with Paramecium caudatum. TiO nanoparticles were synthesized at a lab scale using high energy ball milling technique; characterized for their physicochemical properties and investigated for their ecotoxicological impact on oxidative stress, steatosis, and apoptosis of cells through different biochemical analysis, flow cytometry, and fluorescent microscopy.
