Titanium dioxide (TiO2
) nanorods and nanoparticles had been successfully done by hydrothermal method and spray
pyrolysis deposition technique, respectively. Form XRD results, crystallite structure for TiO2
nanorods is rutile phase
at 2θ degree 27.5° which corresponded to [110] orientation. Whereas, TiO2
nanoparticles produced anatase phase at
2θ degree 25.3° which corresponded to [110] plane. The structure of nanorods and nanoparticles were characterized
using FESEM. The size of nanorods was in the range of 80 to 100 nm. While, the nanoparticles size was ranging from
25 to 35 nm. The HeLa cells were grown on those TiO2
and were observed under fluorescence microscope. The cells
showed healthy sign of growth on TiO2
nanorods and nanoparticles substrates. Thus, TiO2
nanorods and nanoparticles
are biocompatible to HeLa cells.
