Green Synthesis of Silver Nanoparticles using Colacasia Escullenta, Abutilon Indicum and Muntinga Calabura

Abstract

The Development of well-grounded and eco-hospitable methods for the synthesis of nanoparticles is an important step in the field of nanotechnology. Silver nanoparticles are dominant because of their exceptional chemical, physical, and biological properties, and hence applications. In the last decade, countless efforts were made to develop green methods of synthesis to avoid the hazardous by products. The advantages of using plant and plant-derived materials for biosynthesis of metal nanoparticles have made a keen remark on researchers to investigate mechanisms of metal ions uptake and bio-reduction by plants, and to understand the possible mechanism of metal nanoparticle formation in plants. This review describes the methods of green synthesis for Ag-NPs and their countless applications. It also narrates the comparison of efficient synthesis methods via green routes over physical and chemical methods, which provide strong corroboration for the selection of suitable method for the synthesis of Ag-NPs. UV-Vis absorption spectroscopy was used to monitor the quantitative formation of silver nanoparticles. The characteristics of the obtained silver nanoparticles were studied using X-ray diffraction analysis (XRD), energy-dispersive spectroscopy (EDX), and scanning electron microscopy (SEM).
