WebApr 10, 2024 · The combination is powerful due to the facile absorption of light by the quantum dots (QDs) that, in turn, transfers energy to the dye via the well-known “FRET” mechanism. Adding value is the fact that the optical properties of QDs can be tuned by synthesizing smaller or larger dots. This size dependence is due to the quantum … WebMay 1, 2015 · The single-molecule analysis of ion channels by means of TIRF imaging, FRET analysis, and subunit counting after photobleaching in living cells has provided useful physiological and pathological information on ion channel functions and a functionally-coupled molecular complex in the cell membrane.
