s.wiegand@fz-juelich.deIt turns out that a simple
non-equilibrium environment created by a temperature
gradient can be used to monitor the reaction kinetics of
large proteins with small substrate molecules. This is
probably caused by a change in the hydration layer of the
protein which is influenced by subtle conformations changes
induced by the binding of the substrate molecule. To get a
better understanding of phenomenon we investigated
systematically various small molecules, microemulsions and
colloids by a holographic grating method called infrared
thermal diffusion forced Rayleigh scattering (IR-TDFRS).
Looking at the various systems we can identify certain rules
of thumb which will be discussed. Open questions such as the
radial dependence of the thermal diffusion coefficient and
its relation with the interfacial tension and charge effects
are considered.},
