Used in photodynamic therapy due to its strong photosensitizing properties. When exposed to light, it generates reactive oxygen species that can destroy cancer cells, making it valuable in oncology research. Also studied for antiviral applications, particularly against enveloped viruses, as it can inactivate them upon light activation. Investigated for use in treating skin disorders and depression, leveraging its interaction with light and biological systems. Its fluorescence is utilized in imaging and tracking cellular processes in research settings.
