Abstract :

Biologically synthesized nanoparticles have been widely used in the field of medicine. The present study reports the green synthesis of silver nanoparticles using of Jatropha gossypiifolia leaves extract with silver nitrate solution as reducing and capping agent. The synthesized silver nanoparticles were analysed through UV-Visible Spectroscopy, X-ray diffraction, Fourier Transform Infrared Spectroscopy, Field Emission Scanning Electron Microscopy and Energy Dispersive X-ray Spectroscopy. The synthesized Silver nanoparticles were spherical in shape with an average size of 50-90 nm. These silver nanoparticles were evaluated for antibacterial activity. The diameter of inhibition Zones around the disk two gram positive bacterial strains Staphylococcus epidermidis and Bacillus subtilis. One gram negative bacterial strains Klebsiella pneumonia. Antifungal activities showed good test organisms, from the result sample candida vulgaris was most effective and has the highest activity. It is concluded that the green synthesis of silver nanoparticles was very fast, easy, cost-effective, eco-friendly and without any side effect.
