Green Synthesis and Characterization of Gold Nanoparticles Using Onion ( Allium cepa ) Extract

Abstract

In the present research program, cost effective and environment friendly gold nanoparticless were synthesized using the onion (Allium cepa) extract as the reducing agent. The nanoparticless were characterized using UV-visble, XRD, and SEM, TEM methods. The absorption peak at 540 nm was found to be broaden with increase in time indicating the polydispersity… (More)
