Cu-Chelated polydopamine nanoparticles as a photothermal medium and “immunogenic cell death” inducer for combined tumor therapy

A Cu( ii )-Chelated polydopamine nano-system (Cu–PDA) acts as photothermal agent (PTA), Fenton-like reaction initiator and “immunogenic cell death” inducer to mediate PTT/CDT synergistical tumor therapy and antitumor immune activation.
