ABSTRACT

Nanotechnology is a novel emerging technology in the field of science. It utilizes materials with a particle range of 1-100nm. Green synthesis of silver Nanoparticles has several advantages over chemical synthesis. Silver Nanoparticles have a special interest due to their remarkable size ranging between 1-100nm and their unique electrical, thermal and optical properties. They can be utilized for industrial applications. They have been reported to show pharmacological properties such as anti-fungal, anti-bacterial, anti-viral, anti-diabetic, and anti-cancer activity. This has increased the choice for a diverse group of consumer products. Researchers have recently focused their attention on AgNPs because of their exceptional protection against a wide range of bacteria, as well as the emergence of drug resistance to extremely used antibiotics. The unique properties of AgNPs have allowed them to be used in a variety of sectors including water treatment, biomedicine, and agriculture. The nano-sized silver particles have been prepared by using different approaches such as ion sputtering, chemical reduction, and sol-gel. The present review reveals the information regarding various approaches to designing green synthesis of Silver Nanoparticles and their biological applications.
