Abstract
Congo red (CR) dye molecules self-associate in water solutions creating ribbon-like supramolecular structures that can bind various aromatic compounds by intercalation, forming mixed supramolecular systems. Mixed supramolecular systems, such as CR-doxorubicin and CR-Evans blue, interact with the surface of carbon nanotubes, leading to their stiffening and ultimately to their breaking and shortening. This work presents a simple method of obtaining short and straight carbon nanotubes with significantly better dispersion in aqueous solutions and consequently improved usability in biological systems.
