This research presents a novel magnesium (Mg₃)·Fe₃O₄-based Magneto-Fluorescent Nanorobot (“MFN”) that self-propels in blood, enabling selective and rapid isolation of cancer cells. The nanobots, modified with EpCAM antibody/transferrin, cyanine 5 dye, G4 dendrimers, and glutathione, demonstrate nearly 100% cancer cell capture efficiency in serum and whole blood, particularly with MCF7 breast cancer cells. The self-propulsion in water, combined with the Fe₃O₄ shell for magnetic guidance, significantly improves sensitivity, efficiency, and speed of cancer cell capture.
