Abstract :
Summary form only given. Two-photon laser scanning microscopy and a new TCSPC imaging technique was used to obtain FRET intensity-lifetime images of living cells. Double exponential decay analysis separated the FRET fluorescence from the fluorescence of the unquenched acceptor molecules.
