Influence of macroporosity on NIH/3T3 adhesion, proliferation, and osteogenic differentiation of MC3T3-E1 over bio-functionalized highly porous titanium implant material
(2018-01-01)
Highly porous Ti implant materials are being used in order to overcome the stress shielding effect on orthopedic implants. However, the lack of bioactivity on Ti surfaces is still a major concern regarding the osseointegration ...
A Review on Bio-functionalization of β-Ti Alloys
(2020-12-01)
β-Ti alloys are known for their very low Young’s modulus, excellent physical properties, and biocompatibility, hence they are considered as attractive metallic materials for long-term bone implant applications. However, ...
Tribocorrosion behaviour of bio-functionalized porous Ti surfaces obtained by two-step anodic treatment
(2020-04-15)
A bio-functionalized porous surface was obtained on Ti by a two-step anodic treatment and its corrosion and tribocorrosion behaviour were evaluated. The first-step provided macro-porosity while the second-step, a ...
Tribo-electrochemical behavior of bio-functionalized TiO2 nanotubes in artificial saliva: Understanding of degradation mechanisms
(2017-01-01)
It has been shown that the synthesis of TiO2 nanotubes by anodization provides outstanding properties to Ti surfaces intended for dental and orthopedic implants applications. Beyond the very well-known potential of these ...
Physicochemical, osteogenic and corrosion properties of bio-functionalized ZnO thin films: Potential material for biomedical applications
(2018-01-01)
Nano-sized zinc oxide (ZnO) is well known for its antibacterial activity and biocompatibility, which make this material a promising candidate to tailor titanium (Ti) implant surfaces. In an optimized scenario, the antibacterial ...
Bisphosphonate-based surface biofunctionalization improves titanium biocompatibility
(2020-11-01)
Novel-biofunctionalized surfaces are required to improve the performance of endosseous implants, which are mainly related to the resistance against biocorrosion, as well as for the consideration of osteoinductive phenomena. ...
Formation and composition of adsorbates on hydrophobic carbon surfaces from aqueous laccase-maltodextrin mixture suspension
(2016-11-01)
A robust procedure for the surface bio-functionalization of carbon surfaces was developed. It consists on the modification of carbon materials in contact with an aqueous suspension of the enzyme laccase from Trametes ...
Albumin biofunctionalization to minimize the Staphylococcus aureus adhesion on solid substrates
(Elsevier Science, 2018-07)
Staphylococcus aureus has become the most common opportunistic microorganism related to nosocomial infections due to the bacteria capacity to form biofilms on biomedical devices and implants. Since bacterial adhesion is ...
Biofunctionalization of titanium surfaces with alendronate and albumin modulates osteoblast performance
(2020-07-01)
Background: Biofunctionalization of titanium surfaces can improve host responses, especially considering the time for osteointegration and patient recovery. This prompted us to modify titanium surfaces with alendronate and ...
d-Amino acid oxidase bio-functionalized platforms: Toward an enhanced enzymatic bio-activity
(Elsevier Science, 2015-11)
The purpose of this work is to study the adsorption process and surface bio-activity of His-tagged d-amino acid oxidase (DAAO) from Rhodotorula gracilis (His6-RgDAAO) as the first step for the development of an electrochemical ...
