Question

Green synthesis of iron nanoparticles from plant extracts

Answer 1

This biogenic reduction of metal ion to base metal is quite rapid, readily conducted at room temperature and pressure, and easily scaled up. Synthesis mediated by plant extracts is environmentally benign the reducing agents involved include the various water soluble plant metabolites (e.g. alkaloids, terpenoids) and co-enzymes. Silver and gold nanoparticles have been the particular focus of plant-based syntheses. Extracts of a diverse range of plant species have been successfully used in making nanoparticles.
