Green Synthesis of Nanoparticles from Natural Resources; Their Study and Applications

Abstract

Green synthesis of nanoparticles via nanotechnology has many potential applications in various fields. The main aim of green synthesis is to decrease the use of toxic chemicals. Nanotechnology is considered as the revolution in the field of science and technology. It involves the manipulation of materials and synthesizes structures of different atoms and molecules on nano-scale having similar chemical composition to larger synthesized nanoparticles which had never been as easy as it has become with the “green-synthesis” methodologies. Using plants and micro-organisms such as bacteria, fungi have thus become biologically safe, cost-effective and environmental-friendly. In this review, we have discussed about green-synthesis and the different techniques that are involved for formation of nanoparticles and focused mainly on gold and silver nanoparticles including their sources and various anti-bacterial, anti-fungal, anti-viral, anti-cancerous, anti-inflammatory, anti-fibrotic properties.
