Interaktionerna mellan en liten molekyl och g-quadruplexes

Let's take as an example a laser repetition rate of 40 MHz. Transient-absorption spectroscopy (TAS), also known as flash photolysis, is an extension of absorption spectroscopy. Ultrafast transient absorption spectroscopy, an example of non-linear spectroscopy, measures changes in the absorbance / transmittance in the sample. Fluorescence-lifetime imaging microscopy or FLIM is an imaging technique based on the differences in the exponential decay rate of the fluorophore from a sample. It can be used as an imaging technique in confocal microscopy, two-photon excitation microscopy, and multiphoton tomography. Time-correlated single-photon counting (TCSPC) precisely records the arrival times of individual photons, enabling measurement of picosecond time-scale differences in the arrival times of photons generated by fluorescent, phosphorescence or other chemical processes that emit light, providing additional molecular information about samples.

This window contains now the TCSPC curves of both dyes. A few parameters are added in the parameter display on the left. TCSPC stands for time-correlated single photon counting. It is a method of using the timing of a pulsed excitation source, like a laser or LED, with the timing of the arrival of single photons on a detector to reconstruct the lifetime decay over many events (repetition of pulses and photons detected).

This means 2-5 V for a logic “high”-level and 0-0.8 V for a logic “low”-level. Most single photon counting detectors and TCSPC electronics have a dead time. After registering one photon the device needs some time to be ready for the next photon to detect. The dead time for TCSPC devices used for the measurement of fluorescence decays are in the range of 25 to 90 ns. Let's take as an example a laser repetition rate of 40 MHz.

This is a Microsoft Windows application originally developed in C#. The main goal of this application is to provide the FLIM community a user-friendly application. Fluortools .Fluorescence Decay and Anisotropy Analysis. PyCorrelate :Pycorrelate computes fast and accurate cross-correlation over arbitrary time lags. Unter zeitkorrelierter Einzelphotonenzählung (englisch time-correlated single photon counting, TCSPC) versteht man eine Technik zur Messung sich zeitlich schnell ändernder (Picosekundenbereich) Lichtintensitäten. However, if it is known that a single photon was detected, the center of the impulse response can be evaluated to precisely determine the arrival time of the photon. Using time-correlated single-photon counting (TCSPC), temporal resolution of less than 25 ps has been demonstrated using detectors with a fall time more than 20 times longer.
