Drug delivery system (DDS). An antitumour drug and tumour-targeting ligands are coupled to carbon nanotubes (CNTs). Tumour-targeting ligands bind to the receptors on the cell membrane and the DDS is transported into the cell. Drug is released from the CNTs into the cell as a result of an acidic milieu.
