• To discuss cell membrane-derived nanomedicines for enhanced cancer treatment.

Main Methods:

• Overview of ferroptosis definition, mechanisms, and inducers.
• Introduction of representative biomimetic nanomedicines from red blood cells, white blood cells, and cancer cells.
• Discussion of multimodal therapeutic strategies combined with ferroptosis induction.

Main Results:

• Cell membrane-derived biomimetic nanostructures show promise in overcoming limitations of traditional ferroptosis inducers.
• Specific examples include nanomedicines derived from erythrocytes, leukocytes, and tumor cells.
• Combining ferroptosis with multimodal therapies enhances oncological treatment efficacy.

Conclusions:

• Biomimetic nanomedicines are a viable strategy for ferroptosis-based cancer therapy.
