Description	Nanotechnology and nanoscience are new areas of research and human cognition. The effects of nanomaterials on humans and the environment are still poorly understood. Because of their much larger surface there is a possibility to occur toxic effects unknown in %22normal%22 materials. The aim of this work was to use the set of the methods for antioxidants capacity determination to compare the effect of multiwall carbon nanotubes (MWCNTs) and magnetic microparticles (MNPs) in concentrations 0, 1 and 10 ug/ml on suspension tobacco culture. After 7-day cultivation, compared to controls, the weight of the cells exposed to 10ug/ml MWCNTs was 3x higher. MNPs did not influence the cells growth, but they induced free radicals and synthesis of antioxidative compounds, especially thiols. In cells exposed to MNPs the total antioxidant capacity was 30 % increased compared to controls, in cells exposed to MWCNTs a slight decrease was observed. This indicates possible changes in whole plants metabolism Nanotechnology and nanoscience are new areas of research and human cognition.
