Vegetables waste for biosynthesis of various nanoparticles

The large number of vegetable wastes produced globally that provide a new source of biomolecules. These biomolecules efficiently used for the synthesis of nanoparticles or vegetable wastes acted as nanofactories. The main advantages of nanoparticles synthesized using vegetable waste are highly biocompatible, insignificant toxic, high reactivity and high stability compare with that of the traditional process that enhances the effectiveness of the nanoparticles toward the end application. In this book chapter, we discuss the various green synthesis processes like ball-milling, microwave irradiation, hydrothermal process, ultra-sound-assisted synthesis, photocatalysis, and magnetic field-assisted synthesis. The formation of carbon-based nanomaterials, mechanism of growth of nanoparticles was also discussed. The controlled morphology of the nanoparticles with the help of different vegetable extracts and conclusion with prospects was also discussed.
