Abstract

To assess the toxicity of carbon nanotubes (CNTs), we modeled the interaction of CNTs with the inorganic component of mammals’ bone tissue, calcium hydroxyapatite (HA), Ca10(PO4)6(OH)2, under the conditions of biomimetic formation of HA/CNT composites containing 0.1, 1, and 5 wt % CNTs. The synthesis products were identified by chemical analysis, X-ray diffraction, thermal analysis, scanning and transmission electron microscopy, and electron diffraction. We assessed the effect of CNTs on the crystallographic and morphological characteristics of nanocrystalline HA, measured the solubility of the HA/CNT composites, and examined their interaction with living organisms (laboratory mice).
