Abstract:
Green synthesis of metal nanoparticles has various advantages over chemical synthesis. Green synthesized nanoparticles are known for their less toxic nature. Beside the toxicity, these are also more stable and eco-friendly. This cost effective approach is utilized in present study for the green synthesis of Titanium dioxide nanoparticles using Sonchus asper leaves aqueous extract. Nanoparticles were synthesized via sol-gel method by using Titanium isopropoxide as a precursor. Synthesized particles were in spherical shaped measuring 9 – 22 nm in size. They were tested against three different bacterial strains Escherichia coli MTCC 40, Staphylococcus aureus MTCC 1144 and Klebsiella pneumoniae MTCC 4030 for antimicrobial screening. Results showed that green synthesized nanoparticles gave better result against Staphylococcus aureus than chemically synthesized nanoparticles as well as standard drugs.
