The present study aims to synthesize Silver Nanoparticles using aqueous extract of powdered bark of Cinnamomum zeylanicum, elucidate its antimicrobial activity and its DNA Damage. The silver nanoparticle preparation was done using “Green Synthesis”. The synthesis of Silver nanoparticles was confirmed by visual detection in which the colorless solution gets changed to a brown colored solution. Further the Characterization was done by UV- Visible Spectroscopy, Energy Dispersive X-ray (EDX), Scanning Electron Microscope (SEM) and FTIR analysis. The size of the silver nanoparticles was found to be 50 – 80 nm. The silver Nanoparticles were checked for their Antibacterial and Antifungal activity through microbiological techniques. The powdered cinnamon bark extract and the solution containing Silver Nanoparticles were tested for DNA damage through Agarose gel electrophoresis. The antibacterial and anti-fungal study showed clear zones of inhibition of microbial growth. The image projected through UV – Trans-illuminator proves that there is no DNA damage, thus indicating that biologically safe silver nanoparticles can be synthesized using Cinnamomum zeylanicum.
