Used as a fluorescent probe in biological imaging due to its strong emission under UV light. It binds selectively to nucleic acids, making it useful in DNA and RNA detection assays. Commonly applied in cell staining techniques to visualize nuclear structures in microscopy. Also employed in photodynamic therapy research for its ability to generate reactive oxygen species when exposed to light. Its fluorescence properties allow real-time monitoring of cellular processes. Widely utilized in biochemical research for tracking molecular interactions and studying cell viability.
