 Nanotechnology is a rapidly growing field of pharmaceutical science that involves the use of particles at the nanoscale level. In recent years, the use of chemical compounds and physical techniques have been prevalent, but the recognition of their harmful effects on health and environment has led to a shift towards greener methods such as using plant extracts and metabolites to produce nanoparticles. Green synthesis is now the buzzword for combining nanoparticles with plants or their metabolites. This method is especially beneficial due to its reduced toxicity compared to conventional methods. In this review, we discussed the various perspectives of using green methods to produce nanoparticles from plants and their metabolites. Characterization methods are also discussed, as well as applications of these nanoparticles. This article was authored by Aman Gore and Narendra Kumar Jain.
