Abstract:

In this work, we report that supramolecular π-π stacking provides a novel approach for highly efficient loading of a chemotherapeutic agent, doxorubicin (DOX), onto the sidewalls of functionalized single walled carbon nanotubes (SWNTs). With a human lymphoma mouse xenograft model, the SWNT-DOX formulation shows many therapeutic advantages over free DOX including prolonged circulation in the blood, increased tumor drug uptake, enhanced therapeutic efficacy and markedly reduced toxic side effects. Pilot study of SWNT-DOX vs. DOXIL with the mouse tumor model is also carried out.
