As proof of concept we use FA as targeting molecules, which conjugated to amino-terminated polyethylene glycol (NH2-PEG-COOH) and polyethylenimine (PEI) to perform cationic polymers (FA-PEG-PEI) via amidation. Aldehyde sodium alginate modified Fe3O4 magnetic particles coated cisplatin (SPION-CDDP) was constructed with the above cationic polymer to obtain composite carriers (FA-PEG-PEI@SPION-CDDP), which then adsorbed TFPI-2 pDNA via electrostatic interaction to obtain the FA-targeted, CDDP, and TFPI-2-coated nanocomposites (FA-PEG-PEI@SPION-CDDP-TFPI-2). In vitro assays indicated that the novel compounds possessed excellent load-carrying capacity and drug stability and showed negligible cytotoxicity and enhanced targetability to FR positive (FR+) NPC HNE-1 cells.
