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.
