                         aligned multiwalled carbonnanotubes (VACNT) is of particular 
                         interest in regenerative medicine. Template-induced 
                         nanohydroxyapatite (HAp) has broad prospects in applied fields of 
                         bone regenerative medicine. Thus, it becomes very attractive a 
                         combination these two excellent materials to bone tissue 
                         engineering applications. VACNT films were produced as a thin 
                         film, using a microwave plasma chamberat 2.45GHz on Ti substrates 
                         (10mmx10mmx1mm). Superhydrophilic VACNT (VACNT-O2) films were 
                         obtained by thein corporation of oxygen-containing groups using a 
                         pulsed-direct current plasma reactor with pure oxygen. The 
                         fabrication of HAp/VACNT-O2 nanocomposites was performed with a 
                         direct electrodeposition of thethin HAp films on the VACNT-O2 
                         films. Results shows that the carboxylic functional groups 
                         directly attached on VACNT-O2 tips after oxygen plasma treat ment 
                         were essential for the acceleration of the OH- formation and the 
                         deposition of plate-like HAp crystals. The temperature effect was 
                         essential to accelerate the production process of the HAp crystals 
                         on VACNT-O2with homogeneity and cristallinity. These findings were 
                         very attractive for application of these new HAp/VACNT-O2 
                         nanocomposites to bone tissue regeneration.",
