Fluorescence correlation spectroscopy (FCS) is a statistical analysis, via time correlation, of stationary fluctuations of the fluorescence intensity. Its theoretical underpinning originated from L. Onsager's regression hypothesis. The analysis provides kinetic parameters of the physical processes underlying … See more Signal-correlation techniques were first experimentally applied to fluorescence in 1972 by Magde, Elson, and Webb, who are therefore commonly credited as the "inventors" of FCS. The technique was further developed … See more The measurement volume is a convolution of illumination (excitation) and detection geometries, which result from the optical elements involved. … See more To extract quantities of interest, the autocorrelation data can be fitted, typically using a nonlinear least squares algorithm. The fit's functional form depends on the type of dynamics … See more FCS almost always refers to the single point, single channel, temporal autocorrelation measurement, although the term "fluorescence correlation spectroscopy" out of its historical scientific context implies no such restriction. FCS has been extended … See more The typical FCS setup consists of a laser line (wavelengths ranging typically from 405–633 nm (cw), and from 690–1100 nm (pulsed)), which is reflected into a microscope objective by a dichroic mirror. The laser beam is focused in the sample, which contains … See more The (temporal) autocorrelation function is the correlation of a time series with itself shifted by time $${\displaystyle \tau }$$, as a function of $${\displaystyle \tau }$$: where $${\displaystyle \delta I(t)=I(t)-\langle I(t)\rangle }$$ is … See more There are two main non-correlation alternatives to FCS that are widely used to study the dynamics of fluorescent species. Fluorescence recovery after photobleaching (FRAP) In FRAP, a region is briefly exposed to intense light, … See more WebFeb 9, 2024 · The National Institutes of Health.
