Abstract: Nanoscience is the study of unique properties of the matter at nanoscale range(10-9m). Two dimensional nanomaterials such as Molybdenum disulphide N.S. are now-a-days used for various biological purposes The N.S. were synthesised using CTAB exfoliation method and synthesis can be confirmed by visualising deep green colour dispersion. The optical and electronic studies confirmed the synthesis of Molybdenum disulphide N.S. The two different concentrations were chosen to study their effect on Vigna radiata that is morphological and biochemical parameters. The root/ shoot length has been observed in which the more effect was observed on roots as compared to shoots. While observing fresh and dry weight more decrease in dry weight has been observed which implies that the higher concentration has been more toxic whereas, no significant effect has been observed on seed germination. To study plant stress tolerance mechanism Catalase and Peroxidase Assay has been performed in which no significant change has been observed in catalase enzyme activity because the cycles associated with catalase might not be affected whereas increase in Peroxidase activity has been observed.
