Abstract

In this paper, we introduce a new biomimetic mineralization method employing nanohydroxyapatite/superhydrophilic vertically aligned multiwalled carbon nanotube (HA/VAMWCNT) nanocomposites as highly stable template materials. The biomineralization was obtained after HA/VAMWCNT nanocomposites were soaked in simulated body fluid (SBF) solution. Structural analysis revealed that the polycrystalline biological apatites were formed due to the high crystallinity of the produced nanohydroxyapatite (HA). These new nanocomposites are a very promising nanobiomaterial due to their excellent calcification in vitro process. (C) 2012 Elsevier B.V. All rights reserved. (AU)
