Platelet Membrane Coated Cu9S8‐SNAP for Targeting NIR‐II Mild Photothermal Enhanced Chemodynamic/Gas Therapy of Triple‐Negative Breast Cancer

not only increases the temperature of the tumour area for PTT, but also boosts CDT and stimulates the release of NO through thermal reactions to improve the effectiveness of GT. Both in vitro and in vivo experimental results validate that C-S@P exhibits minimal side effects and represents a multifunctional nano-drug targeted at tumors for efficient treatment. This approach promises significant potential for TNBC therapy and broader applications in oncology.
