Fluorescent quantum dots are widely used in biological imaging due to their bright and stable fluorescence, enabling detailed visualization of cellular structures and processes. They are also applied in medical diagnostics for detecting diseases at an early stage through targeted imaging. In electronics, quantum dots enhance display technologies by providing vibrant colors and energy efficiency in QLED TVs and monitors. Additionally, they are utilized in solar cells to improve light absorption and energy conversion efficiency. Their tunable optical properties make them valuable in research, particularly in tracking molecular interactions and studying dynamic biological systems.
