Notes:
Crystalline hydroxyapatite thin coatings have been prepared using a novel opposing RFmagnetron sputtering approach at room temperature. X-ray diffraction (XRD) analysis shows thatall the principal peaks are attributable to HA, and the as-deposited HA coatings are made up ofcrystallites in the size range of 50-100nm. Fourier transform infrared spectroscopy (FTIR) studiesreveal the existence of phosphate, carbonate and hydroxyl groups, suggesting that HA coatings arehighly crystalline. To study the biocompatibility of these coatings, murine osteoblast cells wereseeded onto various substrates. Cell density counts using fluorescence microscopy show that thebest osteoblast proliferation is achieved on an HA RAMS-coated titanium substrate. Theseexperiments demonstrate that RAMS is a promising coating technique for biomedical applications
