چکیده
We report the creation of motif-based artificial proteins that bind to titanium surfaces and mediate the deposition of crystalline calcium phosphate. These proteins enabled in aqua surface modification of titanium materials having an intricate structure used in medical applications.

Effect of Decorating Titanium with Different Self-Assembled Monolayers on the Electrodeposition of Calcium Phosphate
Calcium phosphate (CaP) ceramics are used in orthopedics and dentistry due to their excellent osseointegration and biocompatibility. The electrodeposition of CaP on titanium alloy covered with self-assembled monolayers (SAMs) was studied with respect to the influence of chain length, end-group charge, and anchoring group. SAMs with end-groups similar to the functional groups on the side chains ...
متن کاملMatrix vesicles: structure, composition, formation and function in calcification.
Matrix vesicles (MVs) induce calcification during endochondral bone formation. Experimental methods for structural, compositional, and functional analysis of MVs are reviewed. MV proteins, enzymes, receptors, transporters, regulators, lipids and electrolytes are detailed. MV formation is considered from both structural and biochemical perspectives. Confocal imaging of Ca(2+) and H(+) were used ...
متن کاملDetermination of the Nucleation and Crystallization Parameters for Making Nanoporous Titanium Phosphate Glass-ceramics
Nanoporous glass-ceramics were prepared with composition 45CaO-25TiO2-35P2O5 (mol%). Two molar percent of Na2O was added as a flux to the composition. With the aforementioned composition, glass melted and crystallized into glass-ceramics containing β-Ca3(PO4)2 and CaTi4(PO4)6 as the main phases. The differential thermal analysis (DTA) was conducted to determine the suitable temperatures f...
متن کاملTheoretical analysis of calcium phosphate precipitation in simulated body fluid.
The driving force and nucleation rate of calcium phosphate (Ca-P) precipitation in simulated body fluid (SBF) were analyzed based on the classical crystallization theory. SBF supersaturation with respect to hydroxyapatite (HA), octacalcium phosphate (OCP) and dicalcium phosphate (DCPD) was carefully calculated, considering all the association/dissociation reactions of related ion groups in SBF....
متن کاملEffects of carboxymethyl cellulose-based saliva substitutes with varying degrees of saturation with respect to calcium phosphates on artificial enamel lesions.
The aim of the present study was to evaluate the effects of experimental saliva substitutes based on carboxymethyl cellulose (CMC) differing in degrees of saturation with respect to calcium phosphates on the mineral loss of enamel in vitro. Demineralized bovine specimens (subsurface lesions) were exposed to one of six experimental CMC-based solutions with theoretical degrees of saturation with ...
