Disclosed herein are compositions and nanoconjugates comprising a micelle construct； an antibody single chain fragment variable (scFv)； a NF-kb inhibitor； and a topoisomerase II inhibitor. Further disclosed herein are methods of delivering a drug molecule to a tumor site of a subject comprising: attaching the drug molecule to a targeted micelle, wherein the targeted micelle comprises a micelle construct and an antibody single chain fragment variable (scFv)； and delivering the drug molecule attached to the targeted micelle to the tumor site through intracellular delivery. Also disclosed herein are methods of treating cancer or inhibiting tumor cell growth comprising administering to a subject in need thereof, a therapeutically effective dosage of a composition comprising a micelle construct, an antibody single chain fragment variable (say), a NF-kb inhibitor, and a topoisomerase II inhibitor.
