Abstract
The time-correlated single photon counting (TCSPC) technique combined with clock oscillator set by the pulsed laser provides a precise measurement of the arrival time of the detected photons with picosecond resolution for a time-scale of hours. If TCSPC is combined with other experimental techniques such as optical spectroscopy and mechanical manipulation, it is possible to coincide the detected fluorescence signal with the changes of the sample properties. High temporal resolution achieved in TCSPC (down to ps) allows us to monitor fast mechanical processes in single molecules. Here we present recent developments in fluorescence correlation spectroscopy (FCS) as well as the combination of TCSPC with optical scanning microscopy and mechanical manipulation by means of an atomic-force microscope (AFM).
