“…AFM image allows us to get more complete information about structure of surface due to visualization of oxidized catalyst particles, which cannot be achieved by standard SEM [20]. Both types of catalyst produce nanotubes of small diameter (height approximately 1.8 nm by AFM data, Figure 4).…”

We report on a method of synthesis of single-walled carbon nanotubes percolated networks on silicon dioxide substrates using monodisperse Co and Ni catalyst. The catalytic nanoparticles were obtained by modified method of reverse micelles of bis-(2-ethylhexyl) sulfosuccinate sodium in isooctane solution that provides the nanoparticle size control in range of 1 to 5 nm. The metallic nanoparticles of Ni and Co were characterized using transmission electron microscopy (TEM) and atomic-force microscopy (AFM). Carbon nanotubes were synthesized by chemical vapor deposition of CH 4 /H 2 composition at 1000 °C on catalysts pre-deposited on silicon dioxide substrate. Before the temperature treatment during the carbon nanotube synthesis, the most of the catalyst material agglomerates, due to the magnetic forces, while during the nanotube growth disintegrates into the separate nanoparticles with narrow diameter distribution. The formed nanotube networks were characterized using AFM, scanning electron microscopy (SEM) and Raman spectroscopy. We find that the nanotubes are mainly single-walled carbon nanotubes with high structural perfection up to 200 µm long with diameters from 1.3 to 1.7 nm consistent with catalyst nanoparticles diameter distribution and independent of its material.

In development of methods of stimulation of regeneration of nerve tissues and creation of new generation bioelectronic devices, studying the interaction of nerve cells with specially developed scaffolds with different characteristics of the surface within a nanometer range is a necessary stage. Carbon nanotubes (CNTs), flexible graphene films rolled up into nanosized cylindrical tubes, may represent a promising mate rial for making these scaffolds. CNTs were obtained by chemical vapor deposition. Analysis of PC12 cells cul tivated on quartz glasses covered with CNT films using electron and optical microscopy have been performed. It has been demonstrated that CNTs stimulate proliferation and do not inhibit neuronal differentiation of the PC12 cells. The possibility of obtaining neurons differentiated from mouse neural stem cells on quartz glasses covered with the CNT films has been shown. The data obtained indicate the possibility of using CNT films produced by chemical vapor deposition on quartz glasses as an electroconductive substrate for obtaining cells of neural origin and, possibly, mature neurons and studying their functions.
