Biomimetic novel nanoporous niobium oxide coating for orthopaedic applications

Comparison of mechanical and corrosion properties of graphene monolayer on Ti–Al–V and nanometric Nb2O5 layer on Ti–Al–V alloy for dental implants applications

“…Moreover, it was found that there is a general relationship between deposition conditions and physicochemical properties of Nb 2 O 5 thin films, but a lack of reports on the biocompatibility of these films is notable [18,[29][30][31]. There has been some previous evidences that niobium oxide films, produced by the sol-gel method, exhibit good biological compatibility [19,[25][26][27][28][29][30][31][32][33][34] and good apatite-inducing ability by immersion in Simulated Body Fluids (SBF) solution [32]. Other works show that, anodized niobium-based oxide coatings exhibit bioactivity in a variety of solutions including calcium-phosphorous solution [33], simulated and human salivas [34] and simulated blood fluid [35,36].…”

Fabrication and characterization of nano-HA-45S5 bioglass composite coatings on calcium-phosphate containing micro-arc oxidized CP-Ti substrates

“…On the other hand, the required time for formation of an apatite layer on HA-BG composites was obtained shorter than for HA, indicating higher bioactivity [7]. Among many methods have been applied to form bioactive films, such as plasma spray [8,9], sol-gel [10][11][12], biomimetic [13,14] and ion implantation [15,16], electrophoretic deposition (EPD) [17][18][19][20] is an effective technique for the fabrication of dense and uniform biomaterial coatings on a substrate even with complex geometries. Moreover, this technique has the advantages of high production rate and low investment cost [21].…”

Electrochemical Corrosion and In Vitro Bioactivity of SiO2:ZrO2-Coated 316L Stainless Steel in Simulated Body Fluid

“…One of the possible ways to control corrosion rate as well as improve the bioactivity in terms of accelerating the HAp growth is surface modification of 316L SS (Ref [10][11][12][13]. Development of ceramic coatings over 316L SS biomedical implants is a promising surface modification strategy to overcome these limitations (Ref [14][15][16][17][18][19][20]. Sol-gel technique is generally preferred to coat ceramic materials because it does not require high temperature treatment and is an easy and costeffective process ( Ref 21).…”
