Tcspc fluorescence lifetime

Fluorescence Lifetime Assays: The fluorescence lifetime is a robust parameter for use in several biological assays. It has the potential to replace conventional measurement techniques, such as absorption, luminescence, or fluorescence intensity. 3 Any change in the physicochemical environment of the fluorophore leads to changes in the fluorescence lifetime. Even if fluorescence is not the fastest decay pathway, the relaxation is a discrete, probabilistic process. As a result, there is some Poisson probability of detecting fluorescence photons. We can detect these photons using a PMT and build up an exponential decay. Fitting this decay gives us the excited state, or fluorescence, lifetime.

The need for measuring fluorescence lifetimes of species in subdiffraction- is that of time-correlated, single-photon counting (TCSPC), which is explained in

A fluorescence lifetime image is obtained by building up a photon distribution over the times, t, of the photons in the laser pulse period, and the scanner position, x, y, during the Tonperiods.

Conventional TCSPC (O’Connor and Phillips, 1984) is a one-dimensional technique, i.e., it records the pho-ton density vs. time only. Lifetime imaging with con-ventional TCSPC devices requires recording the decay curve in one pixel, then reading out the data, and proceeding to the next pixel. Although such slow scan

We use a femto second laser and a Becker and Heckl TCSPC card to conduct fluorescence lifetime experiments (TCSPC). We use nile red in an oil to perform Can anyone give some advice on TCSPC setup for fluorescence lifetime experiment?

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. For this purpose both optical events are converted into electrical puls-es.

the lifetime of a single-exponential fluorescence fluorescence and phosphorescence lifetime images in laser scanning systems. It is based on modulating a high-frequency pulsed laser synchronously with the pixel clock of the scanner, and recording the fluorescence and phosphorescence signals by multi-dimensional TCSPC.
