Used in research settings as a fluorescent probe to study cellular processes, particularly in imaging applications where tracking molecular interactions in live cells is required. Its structure allows for high sensitivity in detecting changes in the local environment, such as pH or viscosity, making it valuable in developing biosensors. Also employed in photodynamic therapy studies due to its ability to generate reactive oxygen species upon light activation. Commonly applied in microscopy and flow cytometry for labeling and visualizing specific biomolecules within complex biological systems.
