Improving the ability of phototherapy to stimulate the systemic immune response to cancer

Phototherapy is a safe and effective method for tumor treatment, including photothermal therapy (PTT) and photodynamic therapy (PDT). PTT refers to the use of laser to activate photothermal conversion agents and use high temperature to kill tumor cells, while PDT stimulates photosensitizers to produce reactive oxygen species (ROS) to kill tumor cells.
