This is a preclinical proof-of-concept study reporting in vivo tumor eradication in a murine model using a novel hafnium-doped hollow Prussian blue nanoplatform combined with radiotherapy, chemotherapy, and photothermal therapy. The work is mechanistic and exploratory, demonstrating biological feasibility but lacks comparators, quantified efficacy endpoints, and any clinical evidence.
Preclinical in vivo proof-of-concept study. Mice with 4T1 tumors; exact cohort size and eligibility criteria not specified in abstract.. Intervention: CMHHND nanoplatform (hafnium-doped hollow Prussian blue nanocatalyst loaded with nuclear-targeted doxorubicin, encapsulated in cancer cell membrane shell) combined with radiotherapy, photothermal therapy, and chemotherapy (RT/PTT/Chemo)..
CMHHND-mediated synergistic therapy (RT/PTT/Chemo) effectively eradicated 4T1 tumors with no apparent systemic toxicity Nanoplatform exhibits dual-enzyme mimic activity (catalase and peroxidase-like) to modulate tumor microenvironment High atomic number of hafnium enhances X-ray deposition for radiosensitization
Systemic toxicity assessment described as 'no apparent' without detailed safety data, biodistribution, or organ pathology metrics. CMHHND-mediated synergistic therapy (RT/PTT/Chemo) effectively eradicated 4T1 tumors with no apparent systemic toxicity
This work is preclinical and does not directly inform clinical practice. It provides mechanistic rationale for a novel multimodal nanoplatform but requires optimization, toxicology assessment, and human translation before clinical relevance can be determined.

Abstract Radiotherapy (RT), a cornerstone of modern oncology, is often hindered by the hypoxic tumor microenvironment (TME), inherent radioresistance, and collateral damage to surrounding healthy tissues. To circumvent these limitations, we developed a biomimetic, interfacially engineered nanoplatform (CMHHND) designed for precision synergistic therapy. The nanoplatform features hafnium-doped hollow Prussian blue (HHPB) nanocatalysts as a functional core, which are loaded with nuclear-targeted doxorubicin and encapsulated within a homologous cancer cell membrane (CM) shell. This macromolecular camouflage grants the system exceptional colloidal stability and superior homotypic targeting capabilities through interfacial molecular recognition. Mechanistically, CMHHND functions as a multimodal agent: it acts as a photothermal agent, a dual-enzyme mimic with catalase (CAT)- and peroxidase (POD)-like activities to modulate the TME, and a radiosensitizer leveraging the high atomic number (Z) of Hf to enhance X-ray deposition. Systematic in vivo experiments confirmed that CMHHND-mediated synergistic therapy (RT/PTT/Chemo) effectively eradicated 4T1 tumors with no apparent systemic toxicity. Our findings highlight that integrating biomimetic interfacial engineering with multifunctional nanocatalysts provides a potent strategy to reverse hypoxia-associated radioresistance, offering a robust paradigm for the design of advanced colloidal nanomedicines in precision cancer therapy.
