عنوان انگلیسی Improve the Medical Properties of Nanocomposite Metal Oxide by Increase the Activity
چکیده انگلیسی مقاله In this work, Enhancement activity of nanocomposite metal Oxide by laser for medical application, nanocomposite metal Oxide we prepared by using a simple Sol-Gel method that used to synthesize and measure (〖TiO〗_2, ZnO/〖TiO〗_2and Cu: ZnO/〖TiO〗_2). X-ray diffraction (XRD) was used to describe the crystalline structures, Cu2O spikes were observed (26.393 °), and the amplitude of these peaks became high with a copper concentration that explained a higher Cu2O mass fraction was provide from the copper load. The pictures from the FTSEM showed that most particles are spherical. The effect of heat treatment and laser on the particle size was substantial as well. The chemical bonds and the functional groups of TiO2 NPs were analyzed using Fourier Transform Infrared Spectroscopy (FTIR) within a 400-4000 cm-1 wavenumber range. The solid and broad O-H stretching peaks, C-H bending, N-H bending, and C-Cl stretching chemical bonds were obtained. The photocatalytic activity of (〖TiO〗_2, ZnO/〖TiO〗_2and Cu: ZnO/〖TiO〗_2) were then evaluated under laser rays. ZnO/TiO2 were calcination at 500 °C showed the highest photoactivity compared to that calcination at 400, 600, and 700°C That has the top activity than Cu: ZnO/TiO2 and titanium oxide consequently The antibacterial activity of the prepared specimens was indicated by the Kirby-Bauer disc method that Enhancement photocatalytic activity by laser. ZnO/TiO2 NPs showed a very efficient antibacterial action against Staphylococcus aureus strains extraordinary antibacterial efficacy against S. aureus bacterium strains
