Why Choose Quantum Dots Over Traditional Fluorophores?
Quantum dots offer several advantages over traditional fluorophores:
1. Photostability: Unlike conventional dyes, quantum dots do not bleach easily, allowing for prolonged imaging sessions. 2. Size-Tunable Emission: The wavelength of light emitted by a quantum dot can be tuned by changing its size. This enables multiplexing, where multiple targets can be labeled and imaged simultaneously. 3. High Brightness: Quantum dots have a higher quantum yield, which translates to brighter signals and better resolution. 4. Broad Absorption and Narrow Emission Spectra: This allows for the excitation of multiple quantum dots with a single light source and reduces spectral overlap, improving the accuracy of multiplex imaging.
