Fcs diffusion law
WebFluorescence correlation spectroscopy ( FCS) is a statistical analysis, via time correlation, of stationary fluctuations of the fluorescence intensity. Its theoretical … WebThe FCS diffusion law intercept ( τ0) quantitatively describes obstructed diffusion in these cases. The τ0 is positive for transient trapping or clustering and negative for meshwork compartmentalization. The magnitude of τ0 for domain confinement increases with confinement size, confinement time, and partitioning into the domains.
