Can the motion of a particle motion in volume of a few femto-litres? It is well known that the observation of a particle is movement by using visible light is well to be impossible because the resolution of a confocal microscope is limited by the wavelength. Although observing the motion of a single particle is not possible, how each particle movers on average can be measured. Today's photometric techniques can estimate the size, the velocity, and the properties of particles by measuring the weak fluctuation of light emitted from nanometer-sized particles through some well-known physical laws. Here, we briefly introduce the basic principles of fluorescence correlation spectroscopy and its applications.
