Opis:
To improve the stability of bone-material connection various surface modifications are applied to titanium based implants. Such new biomaterials require detailed characterization, including their biocompatibility. In the present study focused ion beam-scanning electron microscope tomography was applied to investigate the internal structure of ceramic coating as well as cell-material interface. Focused ion beam-scanning electron microscope tomography involves repeated focused ion beam milling and subsequent scanning electron microscope imaging of exposed sample surface and is followed by 3D reconstruction. This approach enables receiving additional information about the sample, unavailable at 2D images. The qualitative and quantitative investigation of pores in the ceramic coating was performed. The porosity of investigated volume: 8.5× 1.1× 3.9 μm³ was calculated as 24%. Additionally, based on 3D reconstruction the visualization of the coherent interface between cell and ceramic coating was done.

Opis:
Subject of this study is surface modification of titanium with thin layers of carbon nanotubes, obtained via an electrophoretic deposition, as a means to improve metal's biocompatibility and provide a suitable matrix for very facile further modifications, if needed. Article presents a preliminary evaluation of the material, using goniometer, scanning electron microscopy and the Raman spectroscopy. The layer is found to be composed of randomly distributed, strongly adhered carbon nanotubes, introducing nanotopography to the surface of titanium. Biological studies were conducted with the human osteoblast-like cell line MG63. Biocompatibility of materials was evaluated using: (a) lactate dehydrogenase cytotoxicity test (LDH) and (b) γ -H2AX genotoxicity test (presence of DNA double strand breaks). Results confirmed non-toxic character of the tested materials. Moreover, carbon nanotubes layers enhanced the biocompatibility properties of titanium substrate - material with carbon nanotubes possessed lower cellular toxic properties even than pure titanium. The result of this preliminary study are very promising and may serve as a starting point for further studies, including further chemical or biological modification of the obtained materials.
