Query: Supramolecular Stacking of Doxorubicin on Carbon Nanotubes for in vivo
  Cancer Therapy   Many therapeutic advantages such as prolonged circulation in the blood,
increased tumor drug uptake, enhanced therapeutic efficacy, and markedly
reduced toxic side effects are provided by a carbon nanotube based
chemotherapeutic formulation. In this system, doxorubicin (DOX) is loaded onto
the sidewalls of functionalized single-walled carbon nanotubes by
supramolecular pi-pi stacking.
