摘要
The present invention relates to a targeted magnetic nanoparticle drug and the preparation method thereof. The targeted magnetic nanoparticle drug comprises an effector molecule and a guidance molecule in a weight ratio of 1 : 0.0001-0.20. The aforesaid effector molecule is a magnetic particle, with a particle size of not more than 1000 nm and a specific adsorption rate (SAR) of 10-7000 W/gFe. The aforesaid guidance molecule comprises an antibody, a ligand or a magnetic particle. The particle size of the aforesaid targeted drug is 2-1000 nm. The targeted magnetic nanoparticle drug is prepared by coupling a magnetic particle and a guidance molecule in a weight ratio of 1 : 0.0001-0.20 in water, organic or inorganic substance or the mixed solution thereof. The resultant targeted magnetic nanoparticle drug can realize targeted magnetic hyperthermia treatment and targeted magnetic thermoablation treatment and prevention on the tumors, and effectively kill the cancer cells, and cure the malignant tumors.
