[The interaction between nerve cells and carbon nanotube networks made by CVD process investigation].

In this research we investigate neuroblastoma cells cultivated on single-walled carbon nanotubes networks made by CVD method on silicon substrates. The complex analysis of grown cells made by atomic force, electron microscopy and Raman spectroscopy was carried out and the effect of nanotube growth process on proliferation factor was investigated. It is shown that despite of a weak decrease in proliferation, cell morphology remains unchanged and no physical or chemical interaction between carbon nanotubes and cells is observed.

[Cultivation of continuous cell lines on the substrate of carbon nanotubes and the effect of electric stimulation on cell proliferation].

It was demonstrated that the three studied samples of carbon nanotubes of domestic production fixed on the substrate surface did not have toxic effect and could be used for cell cultivation. A biocompatible conductive coating based on carbon nanotubes and bovine serum albumin was developed. The efficacy of the coating for growing in vitro cell cultures was tested.

Proliferative activity and viability of fibroblast and glioblastoma cell on various types of carbon nanotubes.

The effects of single-walled and multiwalled carbon nanotubes on proliferative activity and viability of human embryo fibroblasts and glioblastoma cells were studied. Low cytotoxic activity of single-walled carbon tubes was demonstrated. Possible mechanisms of nanotube effects on cell growth are discussed.
