Tumor hypoxia markers and immune response activation were assessed, along with the impact on pain relief biomarkers.Results: (Q+M/MnOx)@Clip successfully mitigated tumor hypoxia, facilitated controlled Q release, and enhanced CDT in vitro and in vivo. The system demonstrated a dual therapeutic effect: anti-tumor immunity and significant cancer pain relief by reducing HIF-1α and VEGF-A levels.Conclusion: The novel (Q+M/MnOx)@Clip system represents a promising advancement in nanomedicine, improving the bioavailability of quercetin and offering a more effective approach to cancer treatment by downregulation of HIF-1α and VEGF-A. This study demonstrates the potential for combining anti-tumor immunity with pain relief for triple-negative breast cancer therapy.Keywords: quercetin, pain relief, cancer immunotherapy, chemodynamic therapy, biomimetic, oxygen generation
