Abstract
Applications of silver nanoparticles (AgNPs) have revolutionized the medicinal industry. Due to small size (1–100 nm) these nanoparticles are able to cross cell and nuclear membrane and induce cyto/genotoxicity. Green synthesized (plant based) AgNPs (GSAgNPs) have emerged as alternative antimicrobial agent to chemically synthesized nanoparticles assuming their methods of synthesis will be environment friendly and non toxic. In this review we report that the GSAgNPs were found to be cytotoxic and genotoxic to different cancer cell lines. They affected cell proliferation caused apoptosis and cell death of human cancer cells but did not cause such damages to normal human peripheral blood lymphocyte cells. This property can be utilized in cancer therapeutics to overcome the major drawbacks of chemotherapeutics with surface modifications of the nanoparticles by adding functionalized AgNPs.
