(Left) Schematic illustration of the design concept for self-assembling drug amphiphiles. The drug loading within the self-assembled nanostructures is defined by the nature of molecular design. (Right) TEM image of nanotubes formed by self-assembly of a drug amphiphile containing four camptothecin drugs. These nanotubes possess a fixed drug loading of 38 percent (w/w).
