Abstract
A Simple Biosynthesis of Silver Nanoparticles from Syzygium cumini Stem Bark Aqueous Extract and their Spectrochemical and Antimicrobial Studies
Highlights
In recent years, an escalating percentage of nanomaterials have emerged, providing advancement in diverse fields (Qu, 2016; Ahmad et al, 2010; Sarkar et al, 2010; Lirdprapamongkol et al, 2010; Nune et al, 2009)
This paper describes a simple biosynthesis of silver nanoparticles (SNs) from aqueous stem bark extract of Syzygium cumini (SC), a natural product
It may be due to the addition of aqueous AgNO3 solution into SC bark extract, that the Ag+ ions were attracted by the -O- group of biomolecules to form silver complex after it was reduced to zero valence of silver (Ago) by free electrons which were produced in the reduction process
Summary
An escalating percentage of nanomaterials have emerged, providing advancement in diverse fields (Qu, 2016; Ahmad et al, 2010; Sarkar et al, 2010; Lirdprapamongkol et al, 2010; Nune et al, 2009). Recent reports suggested biosynthesis of Ag and Au nanoparticles from apiin (Kasthuri et al, 2009), Cinnamon zeylanicum bark extract (Sathishkumar et al, 2009), mushroom extract (Philip, 2009), Acalypha indica leaf extracts (Krishnaraj et al, 2010), glucose and starch (Raveendran et al, 2006) The biosynthesized nanoparticles such as Au, Ag, and Pt are widely used in medical and pharmaceutical applications (Singh et al, 2013; Galdiero et al, 2011) for catalysis (Burda et al, 2005), anti-bacterial, antiviral agents (Singh et al, 2013) and sensor applications (Nirlipta et al, 2016). To the best of author’s knowledge there have been no reports on the biosynthesis of nano silver from the aqueous extracts of the SC bark, their spectro-chemical and anti-bacterial studies
