Utility of macrophages in an antitumor strategy based on the vectorization of iron oxide nanoparticles

Anticancer using Fe₂O₃-laden macrophages. Macrophages derived from patients are treated by Fe₂O₃ nanoparticles and reinjected into the bloodstream. They are attracted by the tumor where they accumulate. Low-intensity radiation activates iron NPs, which release toxic photoelectrons in the tumor, leaving the surrounding tissue...
