Chapter 11 - Green synthesis of metallic nanoparticles: a review

Abstract

Green synthesis of nanomaterials refers to the synthesis of different metal nanoparticles using bioactive agents such as plant materials, microorganisms, and various biowastes including vegetable waste, fruit peel waste, eggshell, agricultural waste, and so on. The growing need to develop “green” and economical synthesis systems for metal nanoparticles has prompted researchers to explore the use of microorganisms, plant extracts, and other biomaterials. The involvement of natural bioactive agents in the synthesis of metal nanoparticles greatly reduces the risk of environmental pollution. Green synthesis of nanoparticles and their applications give an insight into the synthesis of nanoparticles utilizing natural routes. It composes interdisciplinary hypotheses, ideas, definitions, models, and discoveries associated with complex prokaryotes and eukaryotes. In this chapter, various biosynthesis procedures for metal nanoparticles are discussed in detail along with elaborated reference to the outcomes of current research activities performed across the globe in the field of nanoparticles synthesis. The chapter provides readers with a detailed account of the mechanism of green synthesis of metal nanoparticles.
