Thermophoresis in colloidal suspensions

R Piazza, A Parola - Journal of Physics: Condensed Matter, 2008‏ - iopscience.iop.org
Thermophoresis 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 …

Active motion of a Janus particle by self-thermophoresis in a defocused laser beam

HR Jiang, N Yoshinaga, M Sano - Physical review letters, 2010‏ - APS
We study self-propulsion of a half-metal coated colloidal particle under laser irradiation. The
motion is caused by self-thermophoresis: ie, absorption of a laser at the metal-coated side of …

Thermal non-equilibrium transport in colloids

A Würger - Reports on Progress in Physics, 2010‏ - iopscience.iop.org
A temperature gradient acts like an external field on colloidal suspensions and drives the
solute particles to the cold or to the warm, depending on interfacial and solvent properties …

Optothermal manipulations of colloidal particles and living cells

L Lin, T Shoji, Y Tsuboi - The journal of physical chemistry letters, 2014‏ - ACS Publications
This Perspective describes recent progress in optical trap**s of nanoparticles based on
localized surface plasmon. This plasmonic optical trap** has great advantages over the …

Manipulation of colloids by a nonequilibrium depletion force in a temperature gradient

HR Jiang, H Wada, N Yoshinaga, M Sano - Physical review letters, 2009‏ - APS
The nonequilibrium distribution of colloids in a polymer solution under a temperature
gradient is studied experimentally. A slight increase of local temperature by a focused laser …

Thermophoresis: moving particles with thermal gradients

R Piazza - Soft Matter, 2008‏ - pubs.rsc.org
Thermophoresis is particle motion induced by thermal gradients. Akin to other
nonequilibrium transport processes such as thermal diffusion in fluid mixtures, it is both …

Quantifying the role of the surfactant and the thermophoretic force in plasmonic nano-optical trap**

Q Jiang, B Rogez, JB Claude, G Baffou, J Wenger - Nano Letters, 2020‏ - ACS Publications
Plasmonic nanotweezers use intense electric field gradients to generate optical forces able
to trap nano-objects in liquids. However, part of the incident light is absorbed into the metal …

Optically controlled thermophoretic trap** of single nano-objects

M Braun, F Cichos - ACS nano, 2013‏ - ACS Publications
Brownian motion is driven by thermal fluctuations and becoming more efficient for
decreasing size and elevated temperatures. Here, we show that despite the increased …
