Metronomic photodynamic therapy (mPDT) is a type of PDT that aims to exert an antitumor effect by continuously exciting a photosensitizer with continuous exposure to weak light. In this study, we fabricated thin-film light-emitting devices by transferring printed wiring onto flexible poly(lactic acid) thin films with the aim of applying mPDT to deep into the body. In addition, we verified the anti-tumor effects of mPDT by irradiating cancer cells and carrier cancer model mice with the light-emitting device.
