The effect of anatase on rutile TIO2 nanoflowers towards ITS photo-catalytic activity on cancer cells

itanium dioxide (Ti02) rutile nanoflowers were fabricated using acidic hydrothermal method. Ti02 nanoflowers were successfully grown on fluorine doped tin oxide (ITO) substrates. The hydrothermal reaction time and amount of titanium butoxide {TBOT) precursors were optimized to be 10 hours and 2 ml,...

Ti02 nanoflowers were successfully grown on fluorine doped tin oxide (ITO) substrates. The hydrothermal reaction time and amount of titanium butoxide {TBOT) precursors were optimized to be 10 hours and 2 ml, respectively. Fabrication of Ti02 using spray pyrolysis technique produced Ti02 nanoparticles. The surface morphology of the Ti02 nanoflowers and nanoparticles were studied using Field Emission Scanning Electron Microscope (FESEM) to detect the changes in surface morphology as a result of varied parameters. The crystalline phases of Ti02 samples were investigated using X-ray Diffractions (XRD). From the XRD analysis, Ti02 nanoflowers produced using the hydrothermal method were of rutile phase while Ti02 nanoparticles produced using the spray pyrolysis technique were of anatase phase. Thus, when the two fabrication processes were mixed, anatase-rutile phased Ti02 particles were produced. Photo-degradation of Ti02 nanoflowers were analyzed using methyl orange dye. UV-Vis-NIR spectrophotometer was used to observe the absorbance of methyl orange before and after UV light exposure to the Ti02 samples. The degradation rates of methyl orange by rutile, anatase-rutile and anatase were 4.35%, 88.8% and 98%, respectively. Thereon, cervical cancer cells were exposed to the Ti02 samples to check the biocompatibility of the fabricated Ti02. The cervical cancer cells showed biocompatibility towards the fabricated Ti02. Lastly, photo-catalytic activity of the fabricated Ti02 was studied on cancer cells. The fabricated Ti02 showed little effect to the cancer cells as no change in cell size were observed after UV exposure due to the low electron excitation on Ti02 surface. Thus, the photo-catalysis reaction did not occur 2016-06 Thesis http://eprints.uthm.edu.my/9975/ http://eprints.uthm.edu.my/9975/2/24p%20NOOR%20SAKINAH%20KHALID.pdf text en public http://eprints.uthm.edu.my/9975/1/NOOR%20SAKINAH%20KHALID%20COPYRIGHT%20DECLARATION.pdf text en staffonly http://eprints.uthm.edu.my/9975/3/NOOR%20SAKINAH%20KHALID%20WATERMARK.pdf text en validuser mphil masters Universiti Tun Hussein Onn Malaysia Fakulti Kejuruteraan Elektrik dan Elektronik
