Considering the increasing demand for titania nanoparticles with controlled quality for various applications, the present work reports the up-scalable synthesis of size-controlled titanium dioxide nanocrystals with a simple and convenient thermal treatment route. Titanium dioxide nanocrystals with tetragonal structure were synthesized directly from an aqueous solution containing titanium (IV) i...
Titanium was treated with 3,4-dihydroxy-L-phenylalanine (DOPA) or dopamine to immobilize bone morphogenetic protein-2 (BMP2), a biomolecule. DOPA and dopamine solutions turned into suspensions, and precipitates were produced at high pH. Both treatments produced a brown surface on titanium that was thicker at high pH than low pH. Dopamine produced a thicker layer than DOPA. The hydrophobicity of...
We report straight pores in titanium dioxide produced by a pattern transfer method with titanium fluoride hydrolysis. The resulting films on fluorine-doped tin oxide had pores with diameters of 30 nm and depths of 500 nm, corresponding to aspect ratios of 1:17.

Previous studies to compare the influence of surface characteristics of dental implants on cell behavior have used model systems to simulate the implant surface. In this study, bone cell interactions with smooth titanium, titanium dioxide-blasted, titanium plasma-sprayed, and hydroxyapatite plasma-sprayed implants, as manufactured for clinical use, were compared. Implants were exposed to neonat...
Titanium dioxide (TiO2) nanofibers with potential applications in the fabrication of dye sensitized solar cells, photocatalysts, gas sensors, and water treatment systems, among others, have been produced at large yield rates utilizing the Forcespinning (FS) technology. This study presents the results of research performed to determine optimal processing parameters to create TiO2 nanofibers at a...
Nowadays green synthesis of metal nanoparticles is a developing area of research. In this study, titanium dioxide nanoparticles were biosynthesized using an aqueous solution of Echinacea purpurea herba extract as a bioreductant. This is novel and interesting method for synthesis of TiO2 nanoparticles. The prepared titanium dioxide nanoparticles were characterized using ultraviolet–visible spect...
Abstract Background and objectives: In this research, the formation of chitosan-TiO2 nanocomposite and its antibacterial effect on Escherichia coli and staphylococcus aureus was investigated Material and Methods: to study the results, we used Scanning electron microscopy (SEM) and transition electron microscopy (TEM) images, infrared (IR) spectroscopy and ultraviolet-visible. Optical Density (O...
