Biocompatible dispersions of carbon nanotubes: a potential tool for intracellular transport of anticancer drugs

摘要

The use of the biocompatible amphiphilic diblock copolymer poly (ethylene glycol-b-propylene sulfide) (PEG_(44)PPS_(20)) allows a tuned loading of doxorubicin onto the surface of non-functionalized multi-walled carbon nanotubes and an efficient cell internalization. The obtained multi-walled carbon nanotube-based systems show enhanced cytotoxic activity with respect to non-vehicled doxorubicin.
