moieties and possesses amphiphilic property by conjugating a hydrophilic dendron on the exterior of the cyclic peptide ring. The diameters of nanofibers that consisted of nanotubes depend on the employed solvent in the self-assembly process, and uniform filaments formed from double amphiphilic nanotubes via hydrophobic interactions between their hydrophobic faces have been observed in water as well
