Abstract :Objective: Nanotechnology is an emerging technology which has wide applications in many fields. Prime concern of research in nanotechnology is the synthesis of nano-material with the controlled size and shape. Recently, biosynthesis of metallic nano-particles has gained popularity owing to its eco-friendliness. The increasing use of Copper nanoparticles insert ignore into journalissuearticles values(CuNPs); in medicine and industry demands an understanding of their potential toxicities. Methods: Genotoxicity of Copper nanoparticles was assessed using the in vitro micronucleus assay which is standard genotoxicity assay. In this study, Copper nanoparticle was tested in the absence and presence of the metabolic activation insert ignore into journalissuearticles values(2% v/v S9 mix);. Human peripheral blood lymphocyte cultures were exposed to Copper nanoparticle, at 5 dose-levels between 0.125 to 2 µL/mL of culture medium in absence and presence of the metabolic activation system. Results: Required level of cytotoxicity insert ignore into journalissuearticles values(55 ± 5% reduction in replicative index, i.e., cytostasis); was observed in absence of the metabolic activation at the test concentration of 2 µL/mL. Therefore dose levels selected for scoring of binucleated cells containing micronuclei were: 0.5, 1, and 2 µL/mL. From the obtained data of MNBN cells insert ignore into journalissuearticles values(Binucleated cells with micronuclei); for all three selected test concentration was found in the range of negative and vehicle control. Conclusion: Our results concluded that, Copper nanoparticle did not induce statistically significant or biologically relevant increase in number of binucleated cells with micronuclei in absence and presence of the metabolic activation.
