Efficient method to produce biomineralizated nanohydroxyapatite/vertically aligned multiwalled carbon nanotube scaffolds

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.

Graphical abstractIn this paper, we introduce a new biomimetic mineralization routine employing nanohydroxyapatite/vertically aligned multiwalled carbon nanotube (HA/VAMWCNT) nanocomposites as highly stable template materials. These findings are proved after 21 days soaked of this new nanocomposite in simulated body fluidis. These new nanocomposites are very promises as nanobiomaterial due to the excellent calcification in vitro process.Figure optionsDownload full-size imageDownload as PowerPoint slideHighlights► Biological apatites were formed on HA/VAMWCNT scaffolds. ► Our approach provides a novel route for biomineralized nanostructured biomaterials. ► Crystalline nanohydroxyapatite sites can play the biomimetic mineralization.
