title: Spectroscopic studies of electrophoretically deposited hybrid HAp/CNT coatings on titanium.
abstract: Carbon nanotubes deposited on the surface of the metal can be used in a wide variety of applications for modern medicine including: sensors and sensor array devices, electrodes for neural system stimulation, scaffolds for improved healing process for bone defects. Additionally it is debated if deposited on the surface of e.g. endoprosthesis, CNT coating can significantly increase the strength of the tissue/bone joint and stimulate a fast integration of the implant and the tissue. The aim of this paper is the analysis of the electrophoretically deposited nanocomposite coating made of hydroxyapatite nanoparticles and carbon nanotubes on the surface of titanium. The paper concentrates on the analysis of the layer's structure and its bioactivity properties. The nanocomposite films were investigated using Raman Spectroscopy as well as AFM and SEM microscopy. The measurements were conducted at every stage of layer preparation and after bioactivity test. Bioactivity was evaluated by in vitro test in Simulated Body Fluid (SBF, 37°C, for 30days). It was shown that hybrid HAp/CNT layers are very attractive materials for modification of the surface of metallic orthopedic implants.
