OBJECTIVES To study the efficacy of an effective anodized titanium surface with enhanced attachment of endothelial progenitor cell (EPC). BACKGROUND In-stent restenosis is a major obstacle for vascular patency after catheter-based intravascular interventions. Recently, stents that capture EPCs have been paid attention in order to make a functional endothelialized layer at the site of stent-in...

In this work, TiO2 nanostructures were grown on titanium thin films by electrochemical anodizing method. The bipolar resistive switching effect has been observed in Pt/TiO2/Ti device. Resistive switching characteristics indicated the TiO2 nanotubes are one of the potential materials for nonvolatile memory applications.  Increasing anodizing duration will increase nanotube lengths which itself c...

BACKGROUND AND OBJECTIVES Although the laser is one of the widely used systems in dental field, literature about the biological effects of laser irradiation on the titanium surface is rare. The aim of this study was to investigate the responses of osteoblast-like cells seeded onto laser irradiated anodized titanium discs, using a CO(2) (carbon dioxide) and Er,Cr:YSGG (erbium chromium-doped yttr...

BACKGROUND Neovascularization over dental implants is an imperative requisite to achieve successful osseointegration onto implanted materials. The aim of this study was to investigate the effects on in vitro angiogenesis of anodized 70 nm diameter TiO2 nanotubes (NTs) on Ti6Al4V alloy synthesized and disinfected by means of a novel, facile, antibacterial and cost-effective method using super ox...

The anodization of titanium involves the formation of a thin, dense and compact, oxide layer. In this process the rutile structure of the original titanium oxide is converted into an anatase structure. It is this anatase structure and how it influences the bonding properties of the sol gel coating of hydroxyapatite (HAp) was the main aim of this research project. "he titanium samples were anodi...

Currently used orthopedic implants composed of titanium have a limited functional lifetime of only 10-15 years. One of the reasons for this persistent problem is the poor prolonged ability of titanium to remain bonded to juxtaposed bone. It has been proposed to modify titanium through anodization to create a novel nanotubular topography in order to improve cytocompatibility properties necessary...

Titanium alloys have been extensively used as promising implant materials. The anodic oxide layer on the surface of this alloy can be a compact, porous or a tubular structure, which has a direct impact on the final characteristics of the implants. In this study, nano topographic oxide arrays were synthesized on the surface of titanium substrates using an anodic oxidation technique. The anodizat...

The surface modification of titanium alloys is an effective method to improve their biocompatibility and tailor the material to the desired profile of implant functionality. In this work, technologically-advanced titanium alloys—Ti-15Mo, Ti-13Nb-13Zr and Ti-6Al-7Nb—were anodized in suspensions, followed by treatment in alkali solutions, with wollastonite deposition from the powder phase suspend...

One approach to improve biological properties of current titanium and CoCrMo implant is to mimic the nanostructures of bone. Surface modification via anodization is popular to create such nanometer surface features on these metallic implants. The objective of the present study was to anodize titanium and CoCrMo and then determine osteoblast adhesion on such materials. Hydrofluoric acid was used...
