Nanoparticles can be engineered to possess unique properties that make them ideal for tumor targeting. Some of these properties include:
1. Size and Shape: Nanoparticles can be tailored to be small enough to penetrate tumor tissues through the enhanced permeability and retention (EPR) effect. 2. Surface Modification: By modifying the surface of nanoparticles, they can be functionalized with ligands, antibodies, or peptides that specifically recognize and bind to tumor cell receptors. 3. Controlled Release: Nanoparticles can be designed to release their therapeutic payload in a controlled manner, ensuring that drugs are delivered at the right time and place.
