Used extensively as a fluorescent probe in biological imaging due to its strong fluorescence properties. It is particularly valuable in studying cellular processes, as it can bind to specific cellular components and emit light under ultraviolet or visible light excitation. This makes it a useful tool in fluorescence microscopy for visualizing and tracking molecules within cells. Additionally, it is employed in the development of optical sensors, where its fluorescence response can be tuned to detect specific analytes or environmental changes. Its high sensitivity and photostability also make it suitable for applications in photodynamic therapy and as a marker in diagnostic assays.
