Abstract
The surfactant-base membrane mimetic supramolecular structures and their reaction on the presence of carbon nanotubes were studied. On an example of cetyltrimethylammonium bromide (CTAB) it was shown that CTAB molecules can form structures which in texture, shape and sizes imitate the morphology of biological membranes, – the sheets with a typical size of several tens of micrometers. It has been established that the presence of carbon nanotubes leads both to the change in the characteristic size of the sheets in the direction of their increase, and the appearance of new structural state – the sheets which form the "flower structures" (nanoflowers). This means that the presence of the carbon nanoparticles may change the geometry of the membrane structure, thereby altering membrane properties and thus causing disturbances in the activity of biological organisms.
