Rapid synthesis of silver nanoparticles from Polylthia longifolia leaves
Journal Title: Asian Pacific Journal of Tropical Disease - Year 2012, Vol 2, Issue 0
Abstract
Objective: Metallic nanoparticles are traditionally synthesized by wet chemical techniques, where the chemicals used are quite often toxic and flammable. In this research article we present a simple and eco-friendly biosynthesis of silver nanoparticles using P. longifolia leaf extract as reducing agent. Methods: Characterization using UV-Vis spectrophotometry, Transmission Electron Microscopy (TEM) was performed. Results: TEM showed the formation of silver nanoparticles with an average size of 57 nm. Conclusions: P. longifolia demonstrated strong potential for synthesis of silver nanoparticles by rapid reduction of silver ions (Ag+ to Ag0). Biological methods are a good competent for the chemical procedures, which are enviro- friendly and convenient.
