Green synthesis of metal nanoparticles by microalgae

Green synthesis of metal nanoparticles through biological resources has attracted attention in recent years. The main reason for that, a lot toxic chemicals as reducing and stabilizing agents are used physical chemical methods which known conventional methods. Organisms such plants, fungi, bacteria, algae alternative sources green nanoparticle because their more eco-friendly nature not be threat to human health. Microalgae aquatic microorganisms have been added into the formulations food, cosmetics, pharmaceutical many years, due high value-added metabolites proteins, vitamins, pigments, fatty acids, intracellular extracellular polysaccharides. In addition, microalgae potential biogenic ions accumulation capability, phytoremediation potential, rich that will reduce elemental state. number studies, focused on silver, gold, titanium, zinc, iron, etc. from species by pathways increased. This review article aims provide brief outline cyanobacteria studied context synthesis, different approaches microalgae, mechanism basic characterization principles antimicrobial activities produced synthesis.
