The invention provides a magnetic targeting Fe 3 O 4 nanoparticle composite, a preparation method and application thereof, and belongs to the technical field of biomedicine. The invention provides a simple, easy and efficient treatment method for superficial solid tumors, that is, under the action of external magnetic force, that is, applying a strong magnetic field at the tumor site, the NK-Fe 3 O 4 complex formed by the action of CD56 antigen antibody. It can feel the force of the magnetic field, so as to reach the tumor site and carry out killing and removal of the tumor, so it has good practical application value. |
