Silver has a wide range of biological applications, more particularly in the form of Nanoparticles. Silver nanoparticles are important due to their exceptional chemical, physical and biological properties. The biomolecules from various plant and microbial species has been used for the synthesis of silver nanoparticles (AgNP’s). More than 100 different biological sources were reported for synthesizing AgNps by various researchers in past decades. The advancement of green synthesis over physical and chemical methods are environment friendly, cost effective and easily scaled up for vast scale synthesis of nanoparticles while high temperature, energy pressure and harmful chemicals are not required for green synthesis The process and source of synthesizing AgNps has a prominent impact on the size, shape and application of AgNPs. In this existing review, an effort has been made to describe different methods for green synthesis of silver nanoparticles.
