“…Such strategies include: surface modifications to reduce concavity, such as polishing; and modification of the physical properties of the device such as surface-free energy. 4,5 Silver is well known for its antimicrobial properties and has been used for many years in the medical field for antimicrobial purposes. 6 Silver impregnated hydroxyapatite film on an alumina substrate has shown excellent antibacterial properties against both Gram-positive and Gram-negative bacteria.…”

“…Recently, interest in titanium oxynitride films has increased and have been extensively studied due to their improved physical and chemical properties, which mainly depend on their N/O ratio. Oxygen-rich TiN x O y films have been used as insulating layer in metal-insulator-metal (MIM) capacitive structures to avoid interfacial oxide layer formation [11], while nitrogen-rich TiN x O y films have been used as an excellent diffusion barrier layer for semiconductor applications [12]; Additionally, many other useful applications of TiN x O y films, such as anti-reflective coating [13] and biomaterials [14] solar selective absorbers [15] and wearresistant coatings [16], have been demonstrated. The wettability studies to determine hydrophilic or hydrophobic nature of titanium oxynitride film are the area that is unexplored and no literature has been found regarding the investigation of this property so far.…”

Titanium oxynitride films were deposited onto commercially pure titanium substrates by direct current reactive magnetron sputtering method using Ti targets and an Ar-N 2 -O 2 mixture discharge gas. The X-ray photoelectron spectroscopy survey spectra on the etched surfaces of TiON films exhibited the characteristic Ti 2p, N 1s, and O 1s peaks at the corresponding binding energies 454.5, 397.0, and 530.7 eV, respectively. The surface topography of these coatings was studied using atomic force microscopy. The characteristic Raman peaks at 200 and 641 cm -1 for the TiN bonds and at 148, 398 ,and 518 cm -1 for the TiO 2 bonds were observed from the Laser Raman spectrometer. The potentiodynamic polarization studies in simulated bodily fluid were performed and the results are reported in this article.

“…Microbial adhesion to surfaces has been shown to be a complex process, involving physicochemical, protein and polysaccharide factors [2,6,7,9,13,16,21,25,26,30]. From an overall physico-chemical point of view, microbial adhesion can be mediated by non-specific interactions, with long-range characteristics, including Lifshitz-van der Waals forces, electrostatic forces, acid-base interactions, and Brownian motion forces [3,37].…”

Staphylococcus epidermidis is now well established as a major nosocomial pathogen associated with infections of indwelling medical devices. The major virulence factor of these organisms is their ability to adhere to devices and form biofilms. However, it has not been established that adherence and biofilm formation are closely linked phenotypes for clinical isolates. In this study, the initial adhesion to different materials (acrylic and glass) of 9 clinical isolates of S. epidermidis, along with biofilmpositive and biofilm-negative control strains, was assayed using physico-chemical interactions to analyze the basis for bacterial adherence to the substratum. X-ray photo electron spectroscopy (XPS) analysis of the cell surface elemental composition was also performed in an attempt to find a relationship between chemical composition and adhesion capabilities. Biofilm formation on the two surfaces was evaluated by dry weight measurements. Human erythrocytes were used to evaluate the ability of S. epidermidis strains to cause hemagglutination, an indicator of the production of a poly-N -acetyl glucosamine cell surface polysaccharide also involved in biofilm formation. The clinical isolates exhibited different cell wall physico-chemical properties, resulting in differing abilities to adhere to surfaces. Adhesion to hydrophobic substrata for all strains occurred to a greater extent than that to hydrophilic surfaces. Bacterial cell hydrophobicity seemed to have little or no influence on adhesion. X-ray photoelectron spectroscopy analysis showed a high ratio of oxygen/carbon for all strains, which is a common characteristic of S. epidermidis species. No relevant relationship was found between XPS data and adhesion values. All strains forming biofilms were able to agglutinate erythrocytes. However, no direct relationship was found between the amount of biofilm formed and the initial adhesion extent. These results indicate that high levels of initial adherence do not necessarily lead to thick biofilm formation. These two aspects of the pathogenesis of medical device related-infection may need to be evaluated independently to ascertain the contribution of each to the virulence of S. epidermidis causing device-related infections.
