Used in photodynamic therapy for cancer treatment due to its ability to generate reactive oxygen species when exposed to light, targeting and destroying cancer cells. It is also studied for its potential in antimicrobial applications, where it can be activated by light to kill bacteria or fungi. Additionally, it serves as a photosensitizer in research related to photosynthesis and chlorophyll degradation pathways, helping to understand plant biology and stress responses. Its fluorescence properties make it useful in imaging and diagnostic studies.
