Linear maltodextrin polymer–folic acid modified graphene oxide nanoparticles for targeted delivery and pH/photothermal sensitive release of hydrophobic anticancer drugs in tumor cells

GO@LM-SP-FA was constructed by connecting linear maltodextrin polymer and folic acid to the surface of graphene oxide nanoparticles. Doxorubicin hydrochloride was loaded into GO@LM-SP-FA to form GO@LM-SP-FA/DOX, and controlled release of anticancer drugs was realized.
