Quantum dots are nanoscale man-made crystals that have the ability to convert a spectrum of light into different colors. Each dot emits a different color depending on its size. (Image: RNGS ...

Figure 1 shows representative examples of blinking in quantum dots and nanowires. An emission ‘trajectory’ from both systems is provided, plotting emission intensity as a function of time.

Bioluminescence is widely used for in vivo imaging of nude mice. By conjugating luciferase protein to quantum dots, bioluminescence resonance energy transfer (BRET) turns these useful fluorophores ...
