Anisotropic thermophoresis [PDF]
Soft Matter, 2017 The thermophoretic force on an elongated colloid oriented with the temperature gradient can be larger or smaller than when oriented perpendicular to it. This anisotropy can translate into a non-vanishing thermophoretic force in the direction perpendicular to the temperature gradient.

A unified description of colloidal thermophoresis [PDF]
The European Physical Journal E, 2018 We use the dynamic length and time scale separation in suspensions to formulate a general description of colloidal thermophoresis. Our approach allows an unambiguous definition of separate contributions to the colloidal flux and clarifies the physical mechanisms behind non-equilibrium motion of colloids.

Thermophoresis for characterizing biomolecular interaction [PDF]
Methods, 2018 The study of biomolecular interactions is crucial to get more insight into the biological system. The interactions of protein-protein, protein-nucleic acids, protein-sugars, nucleic acid-nucleic acids and protein-small molecules are supporting therapeutics and technological developments.

Recent Progress in Optical‐Resonance‐Assisted Movement Control of Nanomotors
Advanced Intelligent Systems, 2020 Light exerts force or torque on objects through the momentum or angular momentum exchange between photons and the objects. For absorbing structures, light also induces a thermal gradient that can be used to power the object movement.

Thermophoretic tweezers for single nanoparticle manipulation
Beilstein Journal of Nanotechnology, 2020 We present the trapping and manipulation of a single nano-object in an aqueous medium by optically induced temporally varying temperature gradients. By real-time object tracking and control of the position of the heating laser focus, we can precisely ...
