Abstract: In nature, there are plenty of materials whose at least one dimension is in the nanoscale like dust particles, smoke, and in biological systems such as proteins, DNA which is 3 nm wide. The study of unique properties of matter whose dimensions are within the nanometer scale is known as nanosciences. The branches of technology that deals with the manipulation of particles that are within the scale of nanometer range are known as nanotechnology. The particles whose dimensions are within the nanometer scale are known as nanoparticles. The size of particles is between 10-100 nm. Nanoplatelets or colloidal nanoplatelets are quasi-two-dimensional sheets of semiconductor material. They show fluorescence in visible spectra. They are formed when liquid phase synthesis of quantum dots are modified. Despite of unique physical and optical properties, area of their studies is still under developed. Here we have used mung bean plant for our study on stress biology because it is readily available here. Morphological data was taken and we found that with an increase in concentration of cadmium ions the weight and height of the plants decreased. Biochemical tests revealed that with an increase in concentration of cadmium nanoparticles, catalase activity and peroxidase activity decreased.
