Nanoparticles has been used in medicine for diagnosis and treatment of various diseases. The current review focuses on the eco-friendly approach to develop nanoparticles of metal, with a special emphasis green synthesized silver nanoparticles. Past few years, due to its good conductivity, chemical stability catalytic and antibacterial activity silver have gained much attention. The diversity and significance of their applications have generated an enormous interest in developing different methods to synthesize silver nanoparticles with well-defined and controlled properties. Various chemicals and physical methods are being explored for production of silver nanoparticles. In which, chemicals are used as reducing agents which subsequently become responsible for various biological risks due to their general toxicity. In addition to chemical and physical methods, a new simple and cheaper technique to synthesize silver nanoparticles utilizes biological tools such as bacteria, yeasts, fungi, and plants. Products from nature or those derived from natural products, such as extracts of various plants or parts of plant, have been used as reducing agent and as capping agents during green synthesis. This technique involved is simple, most stable, and generally one-pot processes compare to other methods. The green synthesis of nanoparticles has been proposed as a cost effective and environmental friendly alternative to chemical and physical methods.
