Green synthesis is defined as the synthesis of nanoparticles using environmentally friendly sources such as bacteria, fungi, and plants. These appealing green strategies are free of the drawbacks that come with traditional synthetic techniques, i.e. they are environmentally friendly. Green synthesis is regarded as a crucial method for reducing the negative impacts of standard nanoparticle synthesis methods routinely used in laboratories and industry. It is a quick and easy way to make a variety of physiologically active chemicals with different molecular configurations. Green synthesis reduces the risk of harmful residues being released into the environment by using environmentally friendly reagents as reducing and capping agents.
