Examination the antibacterial activity for the TiO2 nanoparticles which is prepared by hydrothermal method and mixed with plant and animal extracts (Onion peels and Chitosan peels)

Abstract

Initial production of the titanium dioxide nanoparticles TiO2 used the hydrothermal process. The onion peels and chitosan peel extracts, which are made using the Bio-synthesize approach. By using (UV-Vis) properties, the structural characteristics of TiO2 and TiO2 with extract from onion peels and chitosan peels were studied, and find the absorption edge of TiO2 NPs, TiO2 + onion peels and TiO2 + chitosan peels is around 236 nm, 244 nm and 237.5 nm respectively. The pattern of TiO2 for a number of peaks suggested a tetragonal rutile phase, according to X-ray diffraction (XRD) research. Energy dispersive X-ray, (EDX) was done for TiO2 NPs, TiO2 + onion peels and TiO2 + chitosan peels. Field emission scanning electron microscopy (FE-SEM) shows that the diameters ranging of TiO2 NPs, TiO2 + onion peels and TiO2 + chitosan peels from (43.32 nm to 47.77 nm), (34.11 nm to 62.77 nm) and (32.22 nm to 35.11 nm) respectively. Studying was done on the effect of TiO2 & TiO2 with extracts nanoparticles on bacterial growth, a variation was observed in the effect of the TiO2 & TiO2 with extracts on the growth of bacteria.
