Schematic overview of both photodynamic therapy (PDT) and sonodynamic therapy (SDT) against cancer. The photo- or sonosensitizers are administered systematically or locally into the tumor tissue. They are then activated by either ultraviolet light or ultrasound radiation, respectively, leading to cancer tissue regression, or in the best-case scenario, eradication.
