Förster Resonance Energy Transfer between Core/Shell Quantum Dots and Bacteriorhodopsin
Figure 2
(a) Jablonski diagram showing FRET between a donor and an acceptor molecule. The purple arrow shows QD absorption, yellow arrow shows vibrational relaxation, and red solid arrow shows fluorescence. Solid blue arrow shows nonradiative energy transfer from the donor QD to acceptor biomolecule. (b) Theoretical FRET efficiency of a 565 nm emission QD (donor)-bR (acceptor) pair over a 0 nm–15 nm dipole separation range. The Förster radius of the QD-bR coupling system is calculated to be 7.94 nm.
