What are the Advantages of Using Quantum Dots in Histology?
Quantum dots offer several advantages over traditional fluorescent dyes and proteins:
Photostability: QDs are more photostable than organic dyes, resisting photobleaching and allowing for longer observation periods. Broad Absorption and Narrow Emission Spectra: This allows for simultaneous multiplexing, where multiple QDs with different emission wavelengths can be excited with a single light source. High Brightness: QDs exhibit high quantum yield, resulting in bright fluorescence that enhances signal detection.
