Nanoparticles are of great scientific interest as they are very efficient due to the high surface area to volume. There are different methods for the synthesis of nanoparticles such as chemical, physical and biological (green synthesis). In green synthesis of nanoparticles environmentally benign materials such as whole cells, metabolites or extracts from plants and microorganisms (fungi, bacteria, algae) are used for the synthesis of nanoparticles. Also a large amount of enzymes, which are capable of hydrolyzing metals are used for the reduction, capping and stabilisation of nanoparticles. Green synthesis of nanoparticles provides advancement over chemical and physical methods as it is safe, simple, cost-effective, relatively reproducible and often results in more stable materials. Nanoparticles have possible applications in diverse areas such as electronics, cosmetics, coatings, packaging, and biotechnology.
