Biogenic Silver Nanoparticles Synthesis Route Based on Microalgae

Abstract

Now a day’s biogenic synthesis of metal nanoparticles have become need of time because of their affordability, biocompatibility, nontoxicity and their economical fabrication. The main driving force for the current research was the algal ability to withstand variable extremes of environmental conditions and several microorganisms like bacteria, virus and fungi for optimal synthesis of silver nanoparticles. Here, we present an economical and biocompatible way for the synthesis of silver nanoparticles (AgNPs) based on Chlorella species. In the present study, algal derived extract was more effective instead of using directly algae to synthesize the silver nanoparticles. The synthesized silver nanoparticles were characterized with the help of standard techniques like UV-visible spectroscopy and Dynamic light scattering. Algal derived AgNPs were in the range of nanoscale which supported the biogenic synthesis method for large scale production of the silver nanoparticles at industrial level. Biogenic synthesis pathway of silver nanoparticles helped us in reducing the greenhouse gases (GHG) and its biodegradability and photocatalytic nature makes them perfect entity for waste water treatment.
