Methods of Synthesis, Characterization and Anticancer Potential of Herbal Silver Nanoparticles: A Review

Cancer is a major cause of death for a huge amount of the population. A large population is suffering from this chronic disease, and various treatments and therapies are developed for the diagnosis of cancer. This review paper focuses on one of the treatments for cancer diagnosis, i.e., herbal silver nanoparticles. Herbal silver nanoparticles are plant-based materials with very less and minimum adverse effects of metals. Metal ions are reduced and stabilized by plant-based reducing and stabilizing agents. Nanoparticles are synthesized by physical, chemical and biological methods. Biological methods have very less toxic and have minimum side effects on the environment. Characterization of synthesized nanoparticles is performed by various techniques like SEM, TEM, UV visible spectroscopy and FTIR. However, full profile characterization of nanoparticles is still a challenge for researchers. Herbal silver nanoparticles have many therapeutic activities like antioxidant, antibacterial and various others, but this review paper has a focus on anticancer evaluation. Herbal silver nanoparticles are reported for their anticancer activities on a large scale. In this review article, we will discuss the methods of synthesis, characterization and anticancer potential of herbal silver nanoparticles.
