Metallic nanoparticles (MNPs), particularly gold nanoparticles (AuNPs) and superparamagnetic iron oxide nanoparticles (SPIONs), are emerging as multifunctional platforms that enhance the sensitivity of cervical cancer to conventional treatments through synergistic mechanisms. Cervical cancer frequently exhibits resistance to radiotherapy (RT) and chemotherapy, driven by HPV-associated molecular alterations and tumor microenvironmental factors. High atomic number (Z) MNPs, such as AuNPs, act as effective radiosensitizers by amplifying localized radiation dose deposition, thereby increasing DNA double-strand breaks and impairing DNA repair processes during RT. In parallel, MNP-mediated reactive oxygen species (ROS) generation and ferroptosis induction further potentiate chemoradiotherapy-induced cytotoxicity and help overcome radioresistance. As targeted drug delivery systems, MNPs enable ligand-directed and stimuli-responsive release of chemotherapeutic agents, enhancing intracellular drug accumulation and circumventing drug resistance mechanisms while reducing systemic toxicity. Moreover, SPIONs and AuNP-based theranostic platforms facilitate image-guided treatment planning and monitoring, supporting precision and adaptive cervical cancer therapy. Collectively, these findings highlight the potential of clinically relevant MNPs as adjuvant modulators of chemoradiotherapy sensitivity, offering promising strategies to improve therapeutic efficacy and personalization in cervical cancer management. © 2026 Chinese Society of Particuology and Institute of Process Engineering, Chinese Academy of Sciences.
