TF and neoplasm: Ge et al. co-encapsulated paclitaxel (PTX) and photosensitizer (5-ALA) into nanoparticles (Tf-5-AlA-PTX-NCs) with magnetic carrier modified by Tf-coupled copolymer Pluronic P123, as a new strategy of combined chemotherapy and photodynamic therapy.74 They proved that Tf-5-ALA-PTX-NCs modified with transferrin ligand showed stronger fluorescence signal in MCF-7 cell xenotransplantation tumor compared with 5-ALA-PTX-NCs treatment, thus enhancing the antitumor effect.
