    Synthesis, Characterization And Cytotoxic Effect Of Zno Nanoparticles Obtained By Mechanical Alloying
    (Oum-El-Bouaghi University, 2014) Benchelia, S.; Benosmane, D.; Mekki, E.; Tabet, N.
    ZnO nanoparticles with different grain sizes have been obtained by mechanical milling, after different treatment times: 3, 6, 12 and 24 hours. The final products have been characterized by different analytical techniques, such as X Ray Diffraction, Photoluminescence, Fourier transform infrared (FTIR) and UV-Visible spectroscopies. The cytotoxic effect of one selected concentration ZnO nanoparticles have been evaluated for paramecium growth kinetics and the mortality rate have been recorded as a function of time. Findings demonstrated that the evolution of the paramecium cell number is clearly affected by ZnO Nps presence.
