In the present generation, there is a commercial demand for silver nanoparticles due to their widespread applications. In this study, silver nanoparticles were synthesized using Carica papaya peel extract as a reducing agent. The synthesized nanoparticles were characterized under UV-Visible spectrophotometer, FTIR, SEM, XRD and TEM. UV-Visible spectrophotometer was used to monitor the formation of silver nanoparticles. The TEM analysis shows that the silver nanoparticles have an average size of 50 nm. X-ray diffraction analysis showed that the particles were crystalline in nature. The antibacterial activity of silver nanoparticles was performed on various gram-positive and gram-negative bacteria. These silver nanoparticles showed a significant cytotoxic effect against both, MCF-7 and Hep-2 cells.
