Calcium Phosphate Coatings

The effect of Mn on the protein adsorption of calcium phosphate coatings is investigated in this work. Mn containing β-tricalcium phosphate (Mn-TCP) is first prepared through a coprecipitation based methods. Then Mn-TCP is dispersed into the fluoridated hydroxyapatite (FHA) precursor sol. Mn-TCP/FHA biphasic coatings are prepared with these sols. After cell culture, it is found the amount of protein adsorbed on the coatings following this rule: Mn-TCP/FHA > β-TCP/FHA > FHA. That is ascribed to two reasons: a) Ca and PO4 releasing can promote the activity of cells; b) Mn releasing promotes protein activation even at quite low concentration.

Calcium Phosphate Coatings

Biomimetic apatite coatings are widely used in orthopaedic applications to provide bioinert material surfaces with bioactive behaviour by means of initiating bone growth at the implant surface. In this study we manufactured biomimetic calcium phosphate coatings consisting of a calcium deficient carbonated apatite by immersing activated titanium platelets into simulated body fluid (SBF). The development of the crystal phases was monitored by X-ray diffractometry (XRD) in addition to Fourier-transform infrared (FT-IR) spectroscopy. After annealing in air up to 600 °C luminescence of the biomimetically derived apatite was observed. The photo-induced emission spectra were recorded in the range from 400-750 nm at excitation wavelengths ranging 238 to 450 nm. A blue (437 nm) and a green (556 nm) emission were found between 200 to 600 °C visually appearing white. The results are discussed in terms of chemical and crystallographic changes in the biomimetic calcium phosphate layer during heat treatment.
