Historically, fluorescence correlation spectroscopy is the mathematical descendant of quasi-elastic light scattering (QELS) spectroscopy.2While both FCS and QELS use a small sample volume to noninvasively probe concentration fluctuations, it is the enhanced sensitivity of fluorescence to conformational, environmental, and chemical changes in a system that allows FCS to be more useful in these scenarios than tracking scattered light.
Theoretically (single-mol. level), resp. Fluorescence correlation spectroscopy (FCS), on the other hand, is well-suited for the intermediate concn. range of about 0.1-100 μm-2. However, FCS in general requires calibration with a std.
