Medicine delivery system for combined precise treatment of breast cancer and application thereof

The invention relates to a medicine delivery system for combined precise treatment of breast cancer and application thereof. Ferroferric oxide is used as a magnetic ligand; meso-porous silicon-graphene nano-sheets are used as basic carriers; medicine delivery carriers are obtained through hydrophilic polymers of polyethylene glycol; the medicine delivery carriers and an insoluble micromolecular chemotherapeutic medicine of adriamycin form a meso-porous silicon-graphene nano-sheet-ferroferric oxide-polyethylene glycol/adriamycin medicine delivery system. The system can be used for the combinedprecise treatment (combining chemotherapy and photothermal therapy) of the breast cancer; the death rate of the breast cancer cells can be obviously improved. Compared with the medicine delivery system built by the prior art, the medicine delivery system has the advantages that various advantages are integrated; the combined targeted treatment of the breast cancer chemotherapy and photothermal therapy can be realized; the
