Synthesis and characterization of silver nanoparticles using aqueous extract goat faecal pellets

The present study deals with synthesis and characterization of silver nanoparticles using aqueous extract of goat faecal pellets. The production of silver nanoparticles was analyzed by preliminary changes of colour from pale yellow to dark brown and it indicates the formation of silver nanoparticles. Further, the nanoparticle was characterized by Surface Plasmon Resonance through UV-Visible spectroscopic analysis. The observation of strong peak at 535.00 nm and it was achieved at 24 hrs. Functional groups of these silver nanoparticles were confirmed by using FTIR. The XRD spectrum also confirmed the formation of silver nanoparticles and the nanoparticle size is 7 nm and shape proved to be spherical nature by SEM analysis. Elemental silver was confirmed by using EDAX analysis.
