XRD results showed the presence of Ag nanoparticles in TiO2 matrix. SEM image confirmed formation of Ag nanoparticles. XPS analysis was utilized to study the chemical state of the Ag/TiO2 nanostructure. Statistical surface analysis revealed that since there is a linear relation between logarithmic diagram of Cq(r) and r < Rc ~ 4 µm for all q, both surfaces have self-affine structure. Formation of Ag/TiO2 nanoparticles led to the reduction of  roughness of the samples from 0.72 nm to 0.61 nm. Ag/TiO2 nanoparticles represented greater hydrophilicity under UV illumination and visible light compared with TiO2. TiO2 thin films and Ag/TiO2 nanoparticles showed an inhibition for proliferation of the bacteria on their surfaces. Antibacterial activity of the samples contributed to the growth inhibition of the bacteria on their surfaces.}, keywords = {Ag Nanoparticles,Hydrophilicity,antibacterial,Roughness,Self-affine}, url = {https://www.physchemres.org/article_3223.html}, eprint = {https://www.physchemres.org/article_3223_5a3eda885aace4336d7fe8803b9e27e0.pdf} }
