DNAzyme-Based Microscale Thermophoresis Sensor
Analytical Chemistry, 2023Microscale thermophoresis (MST) technology has emerged as a powerful growing method in a molecular interaction study by measuring fluorescence responses of molecules inside a capillary to infrared (IR) laser heating with the benefits of rapid ratiometric measurement, separation-free, no immobilization, and low sample consumption.

Particle thermophoresis in liquids
The European Physical Journal E, 2004We present a microscopic description of thermophoretic phenomena in dilute suspensions of spherical colloids. The specific particle/solvent interfacial interactions generate a force density field F on the surrounding fluid which in turn gives rise to an "effective force" on the colloid.

Soviet Physics Uspekhi, 1979
We analyze the mechanisms that cause the motion of objects suspended in inhomogeneously heated gases. We treat two limiting cases: a) a highly rarefied gas in which the mean free path λ of the gas molecules is large in comparison with the characteristic dimension R of the object, and b) a weakly rarefied gas that satisfies the condition λ R.

Journal of Colloid and Interface Science, 1973
Abstract Experimental evidence of thermophoresis in liquids is reported for 1.011 and 0.790 μm latex spheres in water and n-hexane. The thermophoretic velocity, vth, was related to the particle and liquid properties by an expression similar to Epstein's gas equation: V th =-0.26 kμ 2k+k p ρT ▽T .

Thermophoresis of single stranded DNA
ELECTROPHORESIS, 2010AbstractThe manipulation and analysis of biomolecules in native bulk solution is highly desired; however, few methods are available. In thermophoresis, the thermal analog to electrophoresis, molecules are moved along a microscopic temperature gradient. Its theoretical foundation is still under debate, but practical applications for analytics in biology

Active thermophoresis and diffusiophoresis
Chinese Physics B, 2022Thermophoresis and diffusiophoresis respectively refer to the directed drift of suspended particles in solutions with external thermal and chemical gradients, which have been widely used in the manipulation of mesoscopic particles. We here study a phoretic-like motion of a passive colloidal particle immersed in inhomogeneous active baths, where the ...

Thermophoresis in colloidal suspensions
Journal of Physics: Condensed Matter, 2008Thermophoresis is particle motion induced by thermal gradients. Akin to other driven transport processes, such as the Soret effect in simple fluid mixtures, or electrophoresis and diffusiophoresis in colloidal suspensions, it is, both experimentally and theoretically, a challenging subject.

Thermophoresis in binary blends
Mechanics of Materials, 2012Abstract Various types of temperature sensitive binary blends are employed in modern technical applications, e.g., polymer solutions in adhesives, lubricants or in coating implementations. In this paper we deduce and thoroughly investigate a model of segregation of such blends in the presence of a locally non-uniform temperature field. Capturing the

Thermophoresis of Graphene Plates
Russian Physics Journal, 2014Thermophoresis of graphene plates in an air medium is discussed within the framework of a molecular-kinetic approach. Its rate is found to be independent of the plate area and the aspect ratio of a rectangular graphene. It does depend on the plate orientation in space, which is controlled by the principle of least resistance.

Thermophoresis of Aerosol Particles
Nature, 1962THE velocity of thermophoresis v of small aerosol particles of radius R, much smaller than the free path λ of the surrounding gas molecules, has been calculated by us1 in two ways: (1) as a limiting case of thermodiffusion; (2) by finding the momentum imparted to the particles by impact of molecules the velocity distribution of which is not disturbed ...
