There is an increasing demand for nanoparticles due to their wide applicability in various areas such as electronics, catalysis, energy, and medicine. In this study synthesis and characterization of silver nanoparticles using Clitorea ternatea flowers is reported. The reduction of silver (Ag+) was monitored using UV- visible spectrophotometry and showed formation of silver nanoparticles in 60mins. The reaction mixture exhibits an absorbance peak around 450 nm characteristic of Ag nanoparticle. Scanning electron microscopy (SEM) analysis showed silver nanoparticles was pure and polydispersed and the size were ranging from 10-50 nm. The approach of green synthesis seems to be cost efficient, eco-friendly and easy alternative to conventional methods of silver nanoparticles synthesis.
