Fluorescence lifetime imaging microscopy: spatial resolution of biochemical processes in the cell.

TL;DR: Fluorescence lifetime imaging microscopy is a technique in which the mean fluorescence lifetime of a chromophore is measured at each spatially resolvable element of a microscope image to allow exploration of the molecular environment of labelled macromolecules in the interior of cells.

Analysis of fluorescence decay kinetics from variable-frequency phase-shift and modulation data

TL;DR: Analysis of fluorescence phase-shift and modulation data by the method of nonlinear least squares to determine the values of the lifetimes and fractional intensities for a mixture of exponentially decaying fluorophores broadly confirms the predicted resolving potential of variable-frequency phase-modulation fluorometry.

Measurements of Subnanosecond Fluorescence Lifetimes with a Cross-Correlation Phase Fluorometer

TL;DR: In this article, the authors considered a single fluorescent species as a detector in which the response to an infinitely narrow pulse of light decays in time, t, according to the exponential law I ( t ) = I(0) x exp (kt).

Influence of Brownian Rotations and Energy Transfer upon the Measurements of Fluorescence Lifetime

TL;DR: In this paper, a system of first-order linear differential equations containing as only parameters the rate of fluorescence emission and rate of transport of the excitation from one orthogonal component of the emission to another is described.

Correction of timing errors in photomultiplier tubes used in phase-modulation fluorometry.

TL;DR: This method is judged to provide more reliable lifetime measurements by the phase and modulation method and to eliminate artifactual photomultiplier effects in measurements of the lifetimes of NADH and indole solutions quenched by iodide.

The Determination of the Fluorescence Lifetimes of Dissolved Substances by a Phase Shift Method

TL;DR: In this article, the lifetime of fluorescent substances is determined by exciting the fluorescence with light modulated at a high frequency and measuring the difference in phase between the exciting light and the resulting fluorescence.
