Green Synthesis and Characterizations of Silver and Gold Nanoparticles

In the last years, biosynthesis of nps have been received considerable attention due to the growing need to develop clean, nontoxic chemicals, environmentally benign solvents and renewable materials [Gericke and Pinches, 2006; Harris and Bali, 2008]. As a result, researchers in the field of nanoparticle synthesis and assembly have turned towards the utilization of biological system such as yeast, fungi, bacteria and plant extracts for the synthesis of biocompatible metal and semiconductor nps through control nucleation and growth of inorganic nps [Kasthuri et al., 2009; Lee et al., 2011; Shankar et al., 2003].
