“…Figure 8 shows SEM images of the PS-TiO 2 electrophoretic deposits, at different magnifications, before and after sintering, demonstrating the successful development of a scaled-structured titania coating of relevance for orthopaedic applications (Radice et al 2008). There is increasing interest in developing EPD of TiO 2 nanoparticles from aqueous suspensions for biomedical applications (Lebrette et al 2006). Moreover Ag-doped TiO 2 nanoparticles are being considered to develop anti-infectious coatings by EPD (Santillán et al in preparation).…”

Electrophoretic deposition (EPD) is attracting increasing attention as an effective technique for the processing of biomaterials, specifically bioactive coatings and biomedical nanostructures. The well-known advantages of EPD for the production of a wide range of microstructures and nanostructures as well as unique and complex material combinations are being exploited, starting from well-dispersed suspensions of biomaterials in particulate form (microsized and nanoscale particles, nanotubes, nanoplatelets). EPD of biological entities such as enzymes, bacteria and cells is also being investigated. The review presents a comprehensive summary and discussion of relevant recent work on EPD describing the specific application of the technique in the processing of several biomaterials, focusing on (i) conventional bioactive (inorganic) coatings, e.g. hydroxyapatite or bioactive glass coatings on orthopaedic implants, and (ii) biomedical nanostructures, including biopolymer-ceramic nanocomposites, carbon nanotube coatings, tissue engineering scaffolds, deposition of proteins and other biological entities for sensors and advanced functional coatings. It is the intention to inform the reader on how EPD has become an important tool in advanced biomaterials processing, as a convenient alternative to conventional methods, and to present the potential of the technique to manipulate and control the deposition of a range of nanomaterials of interest in the biomedical and biotechnology fields.

“…16) The non-uniformity is thought to be due to gaseous emission at the anode by water electrolysis, which causes defects in the microstructure of the TWB surface. 17) The cross sectional SEM micrograph shows that there is sufficient space for bone ingrowth, even after anodic oxidation (Fig. 2(b)).…”

New Development of Titanium Wire Ball as Vertebra Substitute

Fabrication of a new ball-shaped titanium material for vertebral compression fracture treatment has been studied using micro-arc oxidation in an electrolyte containing hydroxyapatite (HAp). To prevent microstructural disturbance on the surface, ethanol was used as a co-solvent. The material thus obtained was found to have high porosity with many micropores, fixed HAp particles on the surface, and elasticity comparable to cancellous bone. Furthermore, it was demonstrated that the materials have osteoconductivity and the elasticity was kept under cycled stress. These indicate that they can be new bone filling materials for percutaneous vertebroplasty (PV).

“…Analogously to the work, 25 ethanol is added to the electrolyte in order to retard the evolution of gas at the anode and prevent the destruction of the growing coating on the titanium surface. Calcium citrate has been added to inhibit the HA transformation into tricalcium phosphate during the PEO process.…”
