“…Untreated surfaces presented three C 1s peaks (284.8, 285.7 and 288.1 eV, Table 5) associated to hydrocarbon contamination (CHx, C-O and C=O bonds) [33][34][35]. After NaOH activation, total carbon presence was lower, and C 1s high resolution spectra was fitted to two peaks at 284.8 and 288.8 eV which can be attributed to C-H and C=O respectively [33][34][35]. These results indicate that Ti_N surfaces were cleaner after the NaOH treatment.…”

Bacterial infection in dental implants along with osseointegration failure usually leads to loss of the device. Bioactive molecules with antibacterial properties can be attached to titanium surfaces with anchoring molecules such as silanes, preventing biofilm formation and improving osseointegration. Properties of silanes as molecular binders have been thoroughly studied, but research on the biological effects of these coatings is scarce. The aim of the present study was to determine the in vitro cell response and antibacterial effects of triethoxysilypropyl succinic anhydride (TESPSA) silane anchored on titanium surfaces. X-ray photoelectron spectroscopy confirmed a successful silanization. The silanized surfaces showed no cytotoxic effects. Gene expression analyses of Sarcoma Osteogenic (SaOS-2) osteoblast-like cells cultured on TESPSA silanized surfaces reported a remarkable increase of biochemical markers related to induction of osteoblastic cell differentiation. A manifest decrease of bacterial adhesion and biofilm formation at early stages was observed on treated substrates, while favoring cell adhesion and spreading in bacteria-cell co-cultures.Surfaces treated with TESPSA could enhance a biological sealing on implant surfaces against bacteria colonization of underlying tissues. Furthermore, it can be an effective anchoring platform of biomolecules on titanium surfaces with improved osteoblastic differentiation and antibacterial properties.

“…[118] Typischerweise enthalten die frisch gebildeten Röhren auch eine geringfügige Menge an Oberflächenhydroxid (zu erkennen am XPS-Peak für O1s), die sich ebenfalls durch Tempern des Materials deutlich verringern lässt. [140,281] In Abbildung 13 d-f sind zwei unerwünschte Effekte dargestellt, die beim Tempern auftreten können. Beim Tempern von Röhren bei T > 450 8C können Risse in den Röhren-wänden auftreten (Abbildung 13 d, e) (zumeist in der OSTSchicht, vgl.…”

TiO2 ist eine der am besten untersuchten Verbindungen in den Materialwissenschaften und weist einige herausragende Eigenschaften auf, die z. B. für die Photokatalyse, für farbstoffsensibilisierte Solarzellen oder für biomedizinische Funktionseinheiten genutzt werden. 1999 zeigten erste Berichte, dass es möglich ist, hoch geordnete Anordnungen von TiO2‐Nanoröhren durch eine einfache, aber optimierte elektrochemische Anodisierung einer Ti‐Metallfolie herzustellen. Dies löste intensive Forschungsaktivitäten aus, deren Schwerpunkt auf der Herstellung und der Modifizierung sowie auf den Eigenschaften und Anwendungen dieser eindimensionalen Nanostrukturen lagen. Dieser Aufsatz geht auf all diese Aspekte und die zugrundeliegenden Prinzipien und funktionellen Haupteigenschaften von TiO2 ein und will außerdem versuchen, Entwicklungsperspektiven für das Gebiet aufzuzeigen.
