“…It has been shown that the addition of the silica into the materials structure has a positive effect on osteoblast response on medical implant surfaces sol-gel titania films. Exploration of the biological response of the TiO 2 -SiO 2 coatings proved their ability to form a tight contact with the surrounding tissues, providing a strong chemical bond with them [77][78][79][80][81].…”

Abstract. Over the last two decades nanotechnology has become one of the most dynamically evolving field of research. The unique properties of nanomaterials, not disclosing at microscale, are examined and exploited to extend our understanding of the interactions taking place at atomic or molecular level. Those findings affect research in many areas, like e.g. alternative energy sources, electronics, physics and medicine. In this paper, the possibility of using nanomaterials for the enhancement of photodynamic activity, is discussed. A brief review on drug-delivery facilitating nanomaterials, regarding their characteristic features, is presented. An exemplary application of silver-doped nanomaterials for enhancement of photodynamic properties of two photosensitizers: Photolon and Protoporphyrin IX, is described. Influence of silver-doped nanomaterials addition on the fluorescence intensity of photosensitizers immobilized in silica-titania (SiO2-TiO2) sol was examined via VIS spectroscopy. Influence of sonication on the fluorescence enhancement was also investigated. It was demonstrated that the fluorescence enhancement of photosensitizers depends on the concentration of both: photosensitizer and silver-doped nanoparticles.

“…For instance, sol-gel TiO 2 -SiO 2 coating made from TEOS and Ti tetraisopropoxide [Ti(OPr i ) 4 ] were deposited on intramedullary NiTi nail implants. They improved bone attachment to the implant and did not crack or peel, even during mechanical distortion (Muhonen et al 2009). Recent in vivo studies in rats showed that such coatings deposited on austenitic steel 316 L also improved the activity of bone marrow multipotent stromal cells (BMSCs) and were able to improve tissue regeneration and their differentiation to bone precursor cells (Śmieszek et al 2014;Marycz et al 2015).…”

“…Several materials are currently used as bioimplant materials, which include metals and alloys, ceramics, polymers, and composites (Ref [1][2][3][4][5]. Among them, 316L stainless steel (SS) is considered as a suitable material for orthopedic applications (Ref [6][7][8], since it has the required mechanical strength besides low cost.…”

The effect of Si:Zr ratio on the in vitro bioactivity and electrochemical corrosion behavior of SiO 2 :ZrO 2 -mixed oxide-coated 316L stainless steel (SS) was evaluated in simulated body fluid (SBF) solution for 72, 120, and 168 h. Growth of Hydroxyapatite (HAp) was accelerated when Si content in the coating was increased. The Zr content in the coating improved the corrosion resistance of 316L SS rather than accelerating the HAp growth. When the Si:Zr ratio was 50:50, the coating exhibited significant improvement in corrosion resistance as well as HAp growth. The mechanism of HAp growth was proposed based on the change in surface zeta potential values of the coatings. Potentiodynamic polarization studies revealed about 10 and 5 times reduction in corrosion current density (i corr ) values for SiO 2 :ZrO 2 (50:50)-coated 316L SS after 168 h of immersion compared to SiO 2 , ZrO 2 , and Si:Zr (70:30) coatings in SBF solutions thus confirming the superior corrosion resistance. The equivalent circuit parameters derived from electrochemical impedance spectroscopy studies further confirmed significant improvement in charge transfer resistance value even after 168 h of exposure.
