Progress in optical manipulation has stimulated remarkable advances in a wide range of
fields, including materials science, robotics, medical engineering, and nanotechnology. This …

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 …

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 …

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 …

This Perspective describes recent progress in optical trappings of nanoparticles based on
localized surface plasmon. This plasmonic optical trapping has great advantages over the …

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 …

Conspectus Optical manipulation techniques are important in many fields. For instance, they
enable bottom-up assembly of nanomaterials and high-resolution and in situ analysis of …

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 is particle motion induced by thermal gradients. Akin to other
nonequilibrium transport processes such as thermal diffusion in fluid mixtures, it is both …

We study the thermal diffusion coefficient DT of a charged colloid in a temperature gradient,
and find that it is to a large extent determined by the thermoelectric response of the …
