Abstract
Lung cancer remains the leading cause of cancer mortality, hindered by drug resistance, limited targeting, and low immunotherapy response. This review presents biomimetic superparamagnetic iron-oxide nanoparticles (SPIONs) as a next-generation theranostic platform. By cloaking SPIONs with cell membranes-macrophage, neutrophil, or cancer cell-we endow them with biological targeting, immune evasion, and deep lung penetration. Coupled with magnetic field-guided retention and real-time imaging, these systems enable precision hyperthermia, on-demand drug release, and immune microenvironment reprogramming. We critically compare membrane types, outline translational challenges, and propose a regulatory-aligned safety framework. This biomimetic strategy offers a dual diagnostic-therapeutic solution for lung cancer and potentially other solid tumors.
