Fluorescence Correlation Spectroscopy

Fluorescence correlation spectroscopy (FCS) was developed in order to char­ acterize the dynamics of molecular processes in systems in thermodynamic equilibrium. FCS determines transport and chemical reaction rates from mea­ surements of spontaneous microscopic thermally driven molecular concentra­ tion fluctuations. Since its inception, and particularly in recent years, techni­ cal and conceptual...
