Abstract

Today the significance of nanoparticles have wide applicable in all fields. The misuse of various plant materials for the biosynthesis of nanoparticles considered a green innovation since it doesn’t include any harmful chemicals. Nano particles with controlled size and synthesis are of principal and mechanical enthusiasm as they give answers for innovative and natural difficulties in the regions of catalysis, medicine, solar energy conversion and water treatment. The present review study manages the green union of metal (silver and gold) and metal oxide (Fe₃O₄ and ZnO) nanoparticles from marine sea weed plants and their vital applications in different fields and furthermore their toxicological studies and the significance of inclining towards the ocean weed plants and their characterization.
