SEAWEEDS: NEW HOPE FOR BIOSYNTHESIS OF METAL NANOPARTICLES- A REVIEW

The nature is the huge “bio-laboratory” and can be explored for the creation of advanced nanoparticles by use of the renewable biological resources like plants, fungi, algae, yeast etc. The nanoparticles designed by means of physicochemical approaches are very destructive for the environment and human health due to involvement of harsh chemicals and stimulate towards the greener and safe approach for the synthesis of nanoparticles. The researchers’ main objective is to design the diverse shapes and sizes of nanoparticles with potential applications which are acting as a driving force to use the unexploited biological renewable resources. The seaweeds are the underexplored natural biological resource for green synthesis of nanoparticles. The natural occurring phytoconstituents in the aqueous extract of marine algae play key role in reduction process and capping agent to create the superior nano scale materials and to make it top contender. The current review draws the major stress on comparison of various approaches to synthesize biocompatible advanced nanoparticles and advantages of green synthesis via seaweeds over the other approaches to scale up at industrial and commercial level in upcoming future.
