GREEN SYNTHESIS: A NOVEL APPROACH FOR NANOPARTICLES SYNTHESISAbstract
There are different types of conventional approaches are used for the synthesis of nanoparticles like physical and chemical techniques. But above approaches used for nanoparticles synthesis is not eco-friendly due to the production of toxic compounds during nanoparticles formation. Therefore, interest in the green synthesis of nanoparticles has been increased. The green synthesis of nanoparticles is an eco-friendly and convenient approach in which there are no adverse effects on the environment. The production of nanoparticles by green synthesis minimizes time and can obtain desired size and shape to increase the constancy of nanoparticles. The living organisms like plant, bacteria, algae, and fungi are known to be capable for production of metals nanoparticles through the intracellular or extracellular mode of biosynthesis. The main reason of involvement of plants, algae especially microorganisms in the production of metal nanoparticles are to develop, immaculate, harmless and environmentally protected production processes for nano synthesis to diminish environmental impact, minimize waste and boost energy efficiency. Therefore, the present review focus on methods concerned on the synthesis of nanoparticles, efforts to merge extensive data reported and methods applied for the synthesis of nanoparticles by using various microbes, algae and plant extracts as well as different techniques involved in the characterization of nanoparticles.
