This paper presents three ways of adapting existing LSMs with time-correlated single photon counting (TCSPC) fluorescence lifetime imaging (FLIM) systems for NIR FLIM: 1) confocal systems with wideband beamsplitters and diode laser excitation, 2) confocal systems with wideband beamsplitters and one-photon excitation by titanium-sapphire lasers

TCSPC is suitable for testing fluorescence lifetime in the range from quantum dots using time correlated single photon counting (TCSPC).

Möchten Sie mehr über Edinburgh Instruments erfahren? Bleiben Sie auf dem Laufenden mit den neuesten Nachrichten und Produktinformationen. Fluorescence lifetime is a significantly more robust measurement of FRET, increased FRET transfer reduced donor lifetime, which can simply be recorded with TCSPC-FLIM. This type of measurement is advantageous as it requires low excitation light levels, it is oblivious to donor concentration, and in addition it provides information about the ratio of interacting versus non-interacting proteins TCSPC .

Tcspc fluorescence lifetime

Our instrumentation covers a combination of the TCSPC technique extended by a multi-wavelength detection scheme. Based on the spectral properties of the participating chromophores their relative contributions to the solved fluorescence measurements with TCSPC in-volves the following steps: First, the time difference between the photon event and the corresponding excitation pulse must be measured.

This short lifetime does not depend on the emission (observation) wavelength (from 550 nm to 750 nm) and it is another candidate for impulse response measurements.
