ALGA Mediated Synthesis of Transition Metal Nanoparticles and to Explore Their Biological and Catalytic Applications

Abstract

In the modern era, nanotechnology is a flourishing area in research work and received prodigious interest due to applications in various fields. Nanotechnology is the branch of science and technology and deals with the fabrication of nano-size substances, their characterization, and applications. Depleting conventional methods of synthesis for nanoparticles, increasing demand, and environmental pollution have diverted the attention of scientists towards the green approach for the synthesis of nanoparticles. The green approach for the synthesis of metal nanoparticles is the latest developing technology and inherits gargantuan attention because it is a simple, facile, pollutant-free, eco-friendly, and low-cost approach. Microalgae are identified as a potential biological resource for the synthesis of metal nanoparticles and reducing, capping, and stabilizing agents for nanoparticles. newlineIn the present work algal strain, B.braunii was isolated from Udaisagar Lake, Udaipur, Rajasthan, India by serial dilution method for synthesis of transition metal nanoparticles as this green alga is a potent source of bioactive molecules. The growth conditions and nutrient medium were standardized for algal cultivation. An economic nutrient medium was formulated to reduce the cost of algal biomass production on a commercial scale. The devised economic medium contained fewer nutrients and that the concentration also reduced. The growth of green alga B. braunii was measured by calculating total chlorophyll content at a regular interval. newline In the present study, grown algal biomass was used to prepare aqueous algal extract for the synthesis of transition metal nanoparticles. Biogenic synthesis is a procedure which is based on green chemistry approaches that have been focused on enviro safe procedure and prevent the uses of hazardous chemicals and high energy demands. Synthesis of metal nanoparticles was accomplished by mixing an aqueous algal extract with an aqueous solution of metallic compounds at suitable parameters like concentration
