Adsorption of poly(rA) on the single-walled carbon nanotubes (SWNTs) surface have been studied by AFM and computer modeling. It follows from AFM images that relatively long fragments of polymers attached to two individual nanotubes in aqueous suspension form branched structures. The size of these structures increases after the addition of a complementary poly(rU) to the aqueous suspension of nanotubes with adsorbed poly(rA), which is induced by hybridization of the adsorbed and free polymer. Molecular dynamic simulation demonstrates different possible structures of these nanohybrids.
