Abstract

Silver nanoparticles have unique physiochemical, biological and environmental properties which make them useful in a wide range of applications. Biosynthesis of silver nanoparticles from Spilanthes calva DC using aqueous leaf extract. 1mM aqueous solution of Silver nitrate was prepared and used for the synthesis of silver nanoparticles. Nanoparticles were characterized were using SEM, EDAX, UV and FT-IR analysis showed the average particle size of 5-50 nm as well as revealed their structure. Silver nanoparticles find their roles in fabric are used to kill bacteria, making clothing odor-resistant etc.

Keywords: Spilanthes calva, SEM, EDAX, FTIR and UV.
