Cyanine7 amine is widely used in biomedical imaging due to its near-infrared fluorescence properties, making it ideal for in vivo imaging applications. It is commonly conjugated to antibodies, peptides, or other biomolecules to target specific cells or tissues, enabling real-time tracking and visualization in research and diagnostics. This dye is particularly valuable in cancer studies, where it helps in tumor detection, monitoring progression, and evaluating treatment efficacy. Additionally, it is employed in molecular biology for labeling and studying cellular processes, such as protein interactions and intracellular trafficking. Its stability and bright emission in the near-infrared range minimize background interference, enhancing imaging clarity and sensitivity.
