It is an age of nanomaterials. Nanotechnology has revolutionized the scientific world. Every sphere of technology has benefited a lot by using nanomaterials. Number of physical and chemical methods is being used for the synthesis of nanomaterials. In recent years much emphasis is given for green synthesis particularly by using plant extracts or microorganism. This is useful for promoting environmental sustainability. Microwave heating and ultrasound techniques are also being used for the synthesis of different type of nanomaterials. Green synthesis is an advance method of synthesizing nanomaterials over other methods because of simplicity, lower cost and relatively reproducible. Plants produce more stable nanoparticles compared to other means and it is very straightforward to scale up. The risk of contamination is also lower. In this article different method of green synthesis of nanomaterials, and applications have been reviewed and discussed.
