Preparations and Applications of Polysaccharide Based Green Synthesized Metal Nanoparticles: A State-of-the-Art

Green chemistry is the torch bearing field of sustainable research where without use of any toxic chemicals, environment-friendly metal nanoparticles are produced. Advantages of green nanoparticle synthesis over chemical-based synthesis are its nearly zero toxicity with wider applications. As the multidrug resistant species begin to emerge, green synthesized nanoparticles have been arisen as a potent alternative of antimicrobials along with various other applications in diverse fields. The main hindrances behind green synthesis are choice of material and its availability. Because of cheaper cost, wide availability, enhanced effectivity and fewer side effects, polysaccharides have successfully replaced the position of chemical reducing agents in nanoparticle synthesis. Our present review focuses on preparation and applications of polysaccharide based metal nanoparticles; a state-of-the-art research with special emphasis on green synthesized silver nanoparticles as a potent source of emerging antimicrobial.
