Synthesis of green silver nanoparticle is carried out by many scientists. Most of them use extracts of plant or microb. In the present research unlike others no extract is used. Rather, seed exudates of Vigna radiata secreted during germination is used for synthesizing colloidal silver nanoparticle. The siver anoparticled were characterized using UV-Vis, fourier transform infrared spectroscopy (FTIR) and transmission electron microscopy (TEM). All these characterization suggested formation of silver nanoparticle comparable with chemical synthesis using sodium borohydrate as reducer.
