Nanotechnology is one branch of modern applied sciences that comprises of biology, physics, chemistry and material sciences and it is largely exploited for the enhancement of develops novel therapeutic agents, nano sized materials for biomedical and pharmaceutical applications etc. The biological syntheses of nanoparticles are mainly done by living organisms such as plant, bacteria, fungi, seaweeds and microalgae. Microbial based nanoparticles fabrication is mainly depending upon extracellular and intracellular enzymatic activities. Plants are enriched with several bio-products such as alkaloids, flavonoids, saponins, steroids, tannins and other nutritional compounds. These natural products play an important role in the synthesis of plant based nanoparticles, moreover plants also comprises of secondary metabolites that could generate nanoparticles. Biogenic approaches are employed for the synthesis of many metallic nanoparticles such as cobalt, copper, silver, gold, palladium, platinum, zinc oxide and magnetite. These biogenic nanoparticles possess lot of biotechnological applications that could be exploited for the betterment of the society.
