Abstract : |
The aim of this study was to find if nanocrystal layers obtained by well-established
nanotechnology are able to induce deposition of hydroxyapatite [Ca10(PO4)6(OH)2]. It is known that
nanosized objects and porous structures influence biological events and they may be used to create
biologically integrated multifunctional devices including biomaterials and sensors. In this work,
sequential physical vapour deposition of CdSe and SiO, or SiOx film was used to modify glass
substrates. To study the ability of the nanostructured surfaces to induce hydroxyapatite deposition,
samples were immersed in a simulated body fluid and simultaneously irradiated with a scanning
laser beam for a few minutes. This resulted in a porous sponge-like non homogeneous
hydroxyapatite layer, consisting of networks of aggregates of nano dimensions on the modified
surfaces. Analysis showed higher Ca and P contents in the stripes of the laser-substrate interaction,
which indicated the influence of the laser energy. The method of laser-liquid-solid interaction used
has led to a synergistic effect due to the simultaneous use of the nanostructured substrate, aqueous
solution and laser energy. |
