Synthesis and Characterization of Tio2 Nanoparticles Using Cynodon Dactylon Leaf Extract for Antibacterial and Anticancer (A549 Cell Lines) Activity

The nano particles are different from the large particles of the same composition because of their large surface area and volume ratio. The metal oxide nanoparticles have received considerable attention on medical line due to their antibacterial properties, resistance against microbes, drug delivery, antibiotics and immune chromatography, tissue / tumour image, anticancer activities and identification of pathogens in clinical specimens [1-2]. TiO2 is the most promising material in the group of the metal oxides. In n type semiconductor, titanium dioxide is a most important semiconductor due to its light absorption, surface adsorption and charge transport properties [3]. TiO2 has three crystal structures namely anatase, rutile, and brookite. In three phases, the anatase phase has got applications in photo-voltaic cells (Fujima and Donald 2000), photo catalysts and more applications for its antimicrobial properties [4].
