Metronomic photodynamic therapy (mPDT) is a type of PDT that aims to exert an anti-tumor effect by continuously irradiating a photosensitizer with weak light. In this study, we developed a flexible light-emitting device using flexible electronics technology to apply mPDT to deep tissues of the body. Specifically, we fabricated a thin-film light-emitting device by transferring printed wiring onto a polylactic acid thin film. We verified its anti-tumor effect in cancer cells and tumor-bearing model mice.
