RGD tripeptide onto perfect and grooved rutile surfaces in aqueous solution: adsorption behaviors and dynamics.
Molecular dynamics (MD) simulations were performed to investigate the adsorption behavior and dynamics of Arg-Gly-Asp (RGD) tripeptide onto the rutile TiO(2) (110) perfect and grooved surfaces in aqueous solution. The simulation results suggest that, driven by the electrostatic attractions between charged groups of the tripeptide and opposite-type charges of the surface atoms, RGD substitutes t...
متن کاملTitanium dental implant surfaces
Osseointegration has been defined as “a direct structural and functional connection between ordered, living bone and the surface of a load-carrying implant”. However, titanium and its alloys cannot directly bond to living bone after being implanted into the body. The osseointegration of titanium dental implants is critically dependent on the implant surface properties. Various surface modificat...
متن کاملProtein adsorption on nanostructured implant surfaces: A model calculation for the prediction of preferred adsorption sites
Introduction Adsorption of proteins at a solid-liquid interface is an important phenomenon in biology and highly relevant for the design of biocompatible materials. It is well-known that protein adsorption is one of the first events which take place when a foreign material comes into contact with a living body and is believed to be a key factor in controlling subsequent cellular adhesion. In th...
متن کاملAdsorption and dissociation of NH3 on clean and hydroxylated TiO2 rutile (110) surfaces: A computational study
The adsorption and dissociation of NH(3) on the clean and hydroxylated TiO(2) rutile (110) surfaces have been investigated by the first-principles calculations. The monodentate adsorbates such as H(3)N-Ti(a), H(2)N-Ti(a), N-Ti(a), H(2)N-O(a), HN-O(a), N-O(a) and H-O(a), as well as the bidentate adsorbate, Ti-N-Ti(a) can be formed on the clean surface. It is found that the hydroxyl group enhance...
متن کاملMussel foot protein-1 (mcfp-1) interaction with titania surfaces().
Marine mussels utilize a variety of DOPA-rich proteins for purposes of underwater adhesion, as well as for creating hard and flexible surface coatings for their tough and stretchy byssal fibers. In the present study, moderately strong, yet reversible wet adhesion between the protective mussel coating protein, mcfp-1, and amorphous titania was measured with a surface force apparatus (SFA). In pa...
