Abstract: Total internal reflection-fluorescence correlation spectroscopy (TIR-FCS) is a powerful method for studying dynamic processes at liquid-solid interfaces that may have numerous applications in biology, physics, and material science. Despite of its power and versatility, however, the use of TIR-FCS is still rather limited. The main reason for this is the need of a complex, in-house constructed optical setup whose assembly and adjustment is a quite difficult task. Clearly, the availability of ready to use, commercial TIR-FCS setups will strongly boost the application of this important method in many research areas. In this note we show that although such setups are still not available in the market, a proper combination of commercial devices for confocal fluorescence correlation spectroscopy and for total internal reflection microscopy may enable TIR-FCS in a way that do not require any special optical alignments. Furthermore, we demonstrate the capabilities of the setup by measuring the diffusion coefficient of single dye molecule and quantum dots in the very proximity of a water-glass interface.
