Emerging ferroptosis-immunotherapy strategies, integrating functionalized nanoplatforms with ferroptosis-inducing agents and immunomodulatory therapeutics, demonstrate significant potential in managing primary, recurrent, and metastatic malignancies. Mechanistically, ferroptosis induction not only directly eliminates tumor cells but also promotes immunogenic cell death (ICD), eliciting damage-associated molecular patterns (DAMPs) release to activate partial antitumor immunity. However, standalone ferroptosis therapy fails to initiate robust systemic antitumor immune responses due to inherent limitations: low tumor immunogenicity, immunosuppressive microenvironment constraints, and tumor microenvironment (TME)-associated physiological barriers (e.g., hypoxia, dense extracellular matrix). To address these challenges, synergistic approaches have been developed to enhance immune cell infiltration and reestablish immunosurveillance, encompassing (1) direct amplification of antitumor immunity, (2) disruption of immunosuppressive tumor niches, and (3) biophysical hallmark remodeling in TME. Rational nanocarrier design has emerged as a critical enabler for overcoming biological delivery barriers and optimizing therapeutic efficacy. Unlike prior studies solely addressing ferroptosis or nanotechnology in tumor therapy, this work first systematically outlines the synergistic potential of nanoparticles in combined ferroptosis-immunotherapy strategies. It advances multidimensional nanopla...
