Abstract: Green synthesis of nanoparticles by using the plant extract has an increased benefit because it is eco-friendly, safe strategic and cost effective, even in the industry it produces much less toxic waste. In the present study we investigated the extract of Allium sativum which is used for the synthesis of biogenic selenium nanoparticles. The bio reduction of selenium nanoparticles was observed due to colour change of the sodium selenite solution and the studied selenium nanoparticles were characterized by UV-Visible spectrophotometer, Transmission electron microscopy (TEM), Fourier transform spectroscopy (FT-IR) and Energy dispersive X-Ray spectroscopy (EDAX). The selenium nanoparticles synthesized by Allium sativum extract observed as hollow and spherical particles in size ranging 7-48nm which found more stable more than two months. The green synthesize selenium nanoparticles significantly inhibited the growth of Escherichia coli and Salmonella typhi.
