Schematic representation of the different tumor targeting strategies compared in the present study. (1) Passive targeting via the EPR effect (PT), (2) active targeting of αvβ3 integrin via RGD grafting (RGD), (3) magnetic targeting via a magnet of 1.1 T placed on the tumor (MT) and (4) the combination of magnetic targeting and active targeting of αvβ3 integrin (RGD + MT).
