Abstract

Synthesis of silver nanoparticles using seeds extract of soy bean has been investigated. The manipulates of
different concentration of soy bean seed extract, same metal ion concentration and different reaction time on
the above cases on the synthesis of nanoparticles were evaluated. Nanoparticles were characterized using UV-
vis transmission electron microscopy (TEM), X-ray diffraction (XRD) and FTIR analysis. XRD studies reveal a
high degree of crystalline and monophasic silver nanoparticles of face-centered cubic structure. FTIR analysis
proved that particles are reduced and stabilized in solution by the capping agent that is likely to be proteins
veiled by the biomass. The present process is an excellent candidate for the synthesis of silver nanoparticles is
simple, easy to perform, pollutant free and inexpensive.
