Sunlight-induced honey-mediated green synthesis of silver nanoparticles

Abstract

Nanotechnology has rapidly advanced over the recent past. Top-down and bottom-up approaches are the two major processes used to synthesize nanoparticles. Most of chemical and physical methods of nanoparticle synthesis are time consuming and costly. Most methods require high temperatures, vacuum conditions or harsh chemicals which may have adverse effects on involved persons. In recent years, researchers have shown immense interest in the environment - friendly green synthesis of nanoparticles. Honey mediated green synthesis is a relatively novel green synthesis method that has been used in recent years to synthesize metal nanoparticles. Honey-mediated green synthesis of nanoparticles is a simple, rapid, cost-effective, biocompatible, reproducible, and safe method. In the present work, we present the sunlight - induced green synthesis of silver nanoparticles using honey from aqueous silver nitrate. We studied the effect of light intensity on the synthesis of silver nanoparticles and also analyzed the growth of the nanoparticles. The particle size is determined from plasmon resonance using Mie theory.
