Biofunctionalization of a “Clickable” Organic Layer Photochemically Grafted on Titanium Substrates

NaOCl-mediated biofunctionalization enhances bone-titanium integration.

The aim of this study was to examine the effect of NaOCl pretreatment on the biomechanical fixation of implant at the early healing stage of a rat model. Polished titanium cylindrical implants and disks were prepared, and one-half of these samples were dual acidetched. Then, one-half of both surfaces were chemically-cleaned by pretreatment with 5% NaOCl solution for 24 h. Morphological analyses...

A comprehensive review of techniques for biofunctionalization of titanium

A number of surface modification techniques using immobilization of biofunctional molecules of Titanium (Ti) for dental implants as well as surface properties of Ti and Ti alloys have been developed. The method using passive surface oxide film on titanium takes advantage of the fact that the surface film on Ti consists mainly of amorphous or low-crystalline and non-stoichiometric TiO(2). In ano...

Binary Adsolubilization of Organic Compounds in a Fluorocarbon Surfactant Adsorbed Layer Formed on Titanium Dioxide

The binary adsolubilization behaviors of 2-naphthol +biphenyl and 2-naphthol +1, 3-dichlorobenzene in a cationic fluorocarbon surfactant adsorbed layer formed on TiO2 have been investigated as a function of pH. In the binary adsolubilization of 2-naphthol+biphenyl, the adsolubilized amount of 2-naphthol increases gradually until pH 7 and then sharply with a further increase of pH, whereas the a...

A Study of ZnO Buffer Layer Effect on Physical Properties of ITO Thin Films Deposited on Different Substrates

The improvement of the physical properties of Indium Tin Oxide (ITO) layers is quite advantageous in photovoltaic applications. In this study the ITO film is deposited by RF sputtering onto p-type crystalline silicon (c-Si) with (100) orientation, multicrystalline silicon (mc-Si), and glass substrates coated with ZnO and annealed in vacuum furnace at 400°C. Electrical, optical, structural a...
