The new approach to obtain multiwalled carbon nanotubes and nanofibers, using shaft furnace with laminar flow of hydrocarbon gas was proposed. The study of reaction ability of different iron salts (FeS, FeCl₃, FeSO₄, carbonyl iron etc) has shown that application of ferric chloride provides the obtaining of the longest carbon catalytic formations and with minimum amount of soot-like inclusions. The purity of catalytic formations of carbon treated with the method of high temperature refining on vacuum at 2 500 ⁰C was 99.97%.

Investigation of biocompatibility of the resulted carbon catalytic formations during contact with cell culture and after implantation to laboratory animals did not show the significant toxic effect.

Key words: carbon nanotubes, toxicity of nanostructures, bioengineering.
