چکیده
In this work the antimicrobial activity of TiO2 nanopore thin films sensitized by Copper tetracarboxyphthalocyanines (TcPcCu) was investigated. TiO2 thin films were deposited by magnetron sputtering and the sensitization process was done by adsorption process. The samples were characterized by scanning electronic microscopy (SEM), Fourier Transform infrared spectroscopy (FTIR), UV-Vis spectrophotometry, diffuse reflectance and Raman spectroscopy. Finally, the antimicrobial effect against Methicillin resistant Staphylococcus aureus (MRSA) under visible irradiation on TiO2 and TcPcCu/TiO2 was studied. The antimicrobial assay showed that TcPcCu/TiO2 thin films reach 80.4% (+/3.4) of inhibition of MRSA growth after visible irradiation.

Zinc Oxide (ZnO) nanorods and titanium dioxide (TiO2) nanostructures thin films were prepared onto glass substrates by the chemical bath deposition (CBD) method. The ZnO was structured as nanorods (NRs) while TiO2 was formed as nanoflowers plate as confirmed by Field-Emission Scanning Electron Microscope (FESEM) images. The ZnO/Fe3O4 and TiO2/Fe3O4 nanostructures thin films were prepared v...

Multi-walled carbon nanotubes (MWCNT)-doped TiO2 thin films were synthesized by the dip-coating method. The obtained products were characterized by SEM, EDX, XRD, and UV-vis absorption spectroscopy. The XRD patterns showed the presence of anatase phase. Absorption spectrum of MWCNT-doped TiO2 revealed a red shift in the optical absorption edge due to carbon doping. The photocatalytic properties...
متن کاملEvaluation of antibiotic activity of methicillin in healing of full-thickness infected wounds with sensitized methicillin resistant Staphylococcus aureus in presence of HAMLET
Objective(s): The novel healing choices for handling of infections due to multidrug resistant Staphylococcus aureus are reguired. HAMLET has been reported to be able to sensitize bacterial pathogens to traditional antimicrobial agents. The aim was to assess wound healing activity of methicillin in presence of HAMLET in methicillin resistant S. aureus (MRSA) infected wounds. Materials and Method...

3 | P a g e Abstract This thesis is concerned with the synthesis and characterisation of TiO2 based photocatalyst thin films and the assessment of their antimicrobial properties. When exposed to light of wavelength less than 380 nm TiO2 films can demonstrate self-cleaning and self-disinfecting properties. This is due to photocatalytic processes occurring on the film surface resulting in film su...
