Abstract: Silver nanoparticles were synthesized at room temperature using fenugreek seed extract. The synthesized silver nanoparticles were characterized using UV-Visible spectroscopy, XRD and particle size analyser. The UV-Vis. spectra showed a red shift with time indicating the increase in particle size. The XRD data revealed that silver nanoparticles crystallizes in fcc structure with a space group of Fm-3m. The average size of the particles was found to be 174 nm.
