عنوان انگلیسی Structural and Antibacterial Properties of Silver Helical Pentagon and L-shaped Nano Sculptured Thin Films
چکیده انگلیسی مقاله Metallic nanostructures have attracted much attention from scientists due to their numerous applications in many areas of physical sciences, chemical sciences, and life sciences. This study showed that by controlling the shape and dimensions of the nanostructures, surface chemistry and their biocidal and antibacterial activities can be managed.In this study sculptured thin films with L- and helical pentagon-shaped were produced by the glancing angle deposition method. in this method by using an angle between the boat of the sample and substrate and simultaneously rotating the substrate about the azimuthal (or normal) axis, the sculptured nanorods were made, this is the creative physical way to produce nanorods with desired shape and porosity. The morphology and structure properties of these thin films were investigated by X-ray diffraction, atomic force microscopy, and scanning electron microscopy. The antibacterial properties of the films against microorganisms such as Escherichia coli ATCC 8739, Pseudomonas aeruginosa ATCC 10145, Staphylococcus aureus ATCC 25923, Micrococcus luteus ATCC 4698, and Candida albicans PTCC 5027 were studied using the so-called diffusion assay method. Sculptured thin film with HP-shaped showed higher antibacterial activity against all of the studied microorganisms than L-shape one. This may be because of increasing the surface-to-volume ratio and higher surface roughness as well as the high intensity of the Ag(111) orientation. Both of the structures have the most antibacterial effect on the Pseudomonas aeruginosa ATCC 10145 bacteria, the ZOI is 3.90 cm for L-shaped and 5.87 cm for HP-shaped sculptured thin film, respectively.
