Biological Synthesis of Nanoparticles: Algae

Abstract

Algae constitute a polyphyletic and non-cohesive grouping of organisms that are capable of performing photosynthesis using oxygen. Although algae have been utilized as biological sources for the green synthesis of metal nanoparticles in the last few years, their usage has been less as compared to other living forms. The different functional groups and enzymes present in the algal cell walls are thought to play an important role in the fabrication of metal and metal oxide nanoparticles. Nanoparticle production has been reported from all algal groups including bluegreen algae, green algae, diatoms, brown algae, and red algae.

Nanomaterials as an alternative to increase plant resistance to abiotic stresses

“…Different techniques to synthesize NPs result in compounds with different shapes, sizes, and biological activities and applications in different areas ( Ali et al., 2021 ; Ali et al., 2021 ). In recent times, the synthesis of metal and metal oxide NPs using plant, fungi and algae extracts has recently emerged in the field of nanoscience and nanobiotechnology, with numerous advantages over conventional physicochemical approaches ( Karthik et al., 2022 ; Srivastava and Bhargava, 2022a ; Srivastava and Bhargava, 2022b ). Chemical reduction is the most common procedure to synthetize NPs.…”
