Effect of polyethylene pretreatments on the biomimetic deposition and adhesion of calcium phosphate films.

Effect of Alkaline-Acid Treatment on the Biomimetic Formation of Calcium Phosphate Layers on Titanium Substrates:An In Vitro Study

Surface Activation of NiTi Alloy by Using Electrochemical Process for Biomimetic Deposition of Hydroxyapatite Coating (TECHNICAL NOTE)

Electrochemical depositions of calcium phosphate (Ca-P) film on NiTi alloy in concentrated simulated body flood (SBF×5) were carried out by cathodic polarization. The Ca-P layer was successfully deposited on Ni-Ti alloy substrate under 10mA/cm2 current density for 2 hours at room temperature. Then, in order to investigate the bioactivity of the pre-calcified samples, they were immersed in SBF f...

Characterization of Biomimetic Calcium Phosphate Deposited on Chitosan for Orthopedic Implant Applications

+Chesnutt, BC; +Yuan YL; *Yang Y; *Ong JL; +Haggard WO; +Bumgardner JD Joint Program in Biomedical Engineering,+University of Memphis and *University of Tennessee-Memphis, Memphis, TN; [email protected] Introduction Chitosan is a deacetylated form of chitin, a natural polysaccharide found mainly in the exoskeletons of crustaceans. Chitosan is an attractive biomaterial because it is very biocom...

The effects of inorganic additives to calcium phosphate on in vitro behavior of osteoblasts and osteoclasts.

This study describes a medium-throughput system based on deposition of calcium phosphate films in multi-well tissue culture plates that can be used to study the effect of inorganic additives on the behavior of osteoblasts and osteoclasts in a standardized manner. All tested elements, copper, zinc, strontium, fluoride and carbonate were homogenously deposited into calcium phosphate films in vary...

Effect of Alkali and Heat Treatment on Biomimetic HA Coating on Ti6Al4V

In this study, time of calcium phosphate formation on Ti6Al4V alloy with or without alkali and heat treatments was investigated. Specimens were soaked in 0, 5, 10 M solutions of NaOH at temperatures of 60 or 80 °C for 24, 72 h. Their surfaces were characterized using scanning electron microscopy and thin film X-ray diffraction. It was found that optimum condition is 72h soaking in 5 M NaOH in 8...
