Biotechnological applications of thermophoresis
Measuring parameters such as stability and con-formation of biomolecules, especially of nucleicacids, is important in the field of biology, medicaldiagnostics and biotechnology. We present athermophoretic method to analyse the conformationand thermal stability of nucleic acids. It relies on thedirected movement of molecules in a temperaturegradient that depends on su...
متن کاملThermophoresis of charged colloidal particles.
Thermally induced particle flow in a charged colloidal suspension is studied in a fluid-mechanical approach. The force density acting on the charged boundary layer is derived in detail. From Stokes' equation with no-slip boundary conditions at the particle surface, we obtain the particle drift velocity and the thermophoretic transport coefficients. The results are discussed in view of previous ...
متن کاملThermophoresis and Thermal Diffusion
Motivation: It turns out that a simple nonequilibrium 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 substrate molecule. The underlying effect is thermoph...
متن کاملThermophoresis of Axially Symmetric Bodies
Thermophoresis of axially symmetric bodies is investigated to first order in the Knudsen-mimber, Kn. The study is made in the limit where the typical length of the immersed body is small compared to the mean free path. It is shown that in this case, in contrast to what is the case for spherical bodies, the arising thermal force on the body is not in general antiparallel to the temperature gradi...
متن کاملAptamer Binding Studies Using MicroScale Thermophoresis.
The characterization and development of highly specific aptamers requires the analysis of the interaction strength between aptamer and target. MicroScale Thermophoresis (MST) is a rapid and precise method to quantify biomolecular interactions in solution at microliter scale. The basis of this technology is a physical effect referred to as thermophoresis, which describes the directed movement of...
