Background:

• Nanomagnetic materials are promising for cancer therapy, but challenges exist in synthesizing low-toxicity, multi-target drug-loaded nanocarriers.
• The precise cancer cell death mechanisms induced by these nanocarriers are not fully understood.

Purpose of the Study:

• To develop a novel inner/outer controlled multi-target magnetic nanoparticle drug carrier.
• To investigate the anti-cancer effects and cell death mechanisms of the developed nanocarrier.
• To address the challenges of low toxicity and multi-target drug loading in nanocarrier synthesis.

Main Methods:

• A liquid photo-immobilization approach was used to functionalize oleic acid-coated Fe3O4 magnetic nanoparticles.
• Doxorubicin, folic acid, tumor necrosis factor-α, and interferon-γ were attached to the nanoparticles.
• Structural and biomedical characterizations were performed, along with in vitro and in vivo anti-cancer effect assessments on HeLa cells.

Main Results:

• The developed magnetic nanoparticle drug carrier demonstrated high efficiency and power in treating cancer cells.
• The treatment induced a valuable programmed cell death mechanism.
• The approach proved effective in overcoming drug resistance in cancer cells.

Conclusions:

• The novel inner/outer controlled multi-target magnetic nanoparticle drug carrier is a powerful tool for cancer therapy.
• The liquid photo-immobilization method offers a viable strategy for creating advanced nanocarriers.
• This approach holds significant potential for overcoming drug resistance and improving cancer treatment outcomes.
