Green synthesis and Anti-bacterial activity of Silver Oxide nanoparticles prepared from Pinuslongifolia leaves extract

There is an increasing commercial demand for nanoparticles due to their wide applicability in various areas such as electronics, catalysis, chemistry, energy, and medicine. Metallic nanoparticles are traditionally synthesized by wet chemical techniques, where the chemicals used are quite often toxic and flammable. So the exploitation of various plant materials for the biosynthesis of nanoparticles is considered a green technology because it does not involve any harmful chemicals. The present study reported the green synthesis of silver nanoparticles using Pinuslongifolia leaves. Green synthesis of silver oxide nanoparticles (AgONps) was carried out using the aqueous extract of Pinuslongifolia leaves. The UV- Vis spectrum was recorded to monitor the formation of the nanoparticles, which exhibited a blue shifted absorption peak at 420 nm. The morphology structure and stability of the synthesized AgO nanoparticles were studied using scanning electron microscope (SEM). Further these biologically synthesized nanoparticles exhibited antibacterial activity against E.coli and Staphylococcus aureus.
