Copper-Doped Nanoscale Covalent Organic Polymer for Augmented Photo/Chemodynamic Synergistic Therapy and Immunotherapy

Due to the specific tumor microenvironment (TME) and immunosuppressive state of cancer cells, conventional antitumor therapies face severe challenges, such as high rates of recurrence and metastasis. Herein, Cu-PPT nanoparticles were synthesized based on copper acetate, p-phenylenediamine, and 5,10,15,20-tetra-(4-aminophenyl)porphyrin via oxidative coupling reaction for the first time, and the resultant product was used for synergistic...
