Культивирование перевиваемых клеточных линий на подложках из углеродных нанотрубок и влияние электростимуляции на пролиферацию клеток

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. A device was developed for electric stimulation of the cells. Local electric potential was applied to the cells using nanoscale electrodes. The results of human embryonic fibroblast cultivation in a pulsed electric field on conductive nanocomposite substrates were presented. An 26% increase in the proliferative activity of cells was observed at potentials up to 100 mV.
