The advancement in the field of nanoscience and nanotechnology to synthesize material at a nanoscale level has proved to have a great effect on the various sciences. In recent times the use green synthesize nanoparticles in field of engineering and biomedicine has gained a huge attention. Unlike the use of chemical method to manufacture the nanoparticle by the use of chemicals that are toxic, expensive and non-ecofriendly. The limitation of the chemically synthesized nanoparticles has generated a need of an alternative means of ecofriendly synthesis process. Green synthesized nanoparticles have emerged as an effective solution to this problem as they are convenient, inexpensive, rapid and eco-friendly. The use of green synthesized nanoparticle has been used as an anti-cancerous agent. This article’s center point is on the application of the green synthesis of nanoparticle and their application as an anti-cancerous agent, their characteristics and the mechanism of the drug action and also the future aspects of the nanoparticle as an anticancer agent.
