abstract = {Colloidal migration in a temperature gradient is referred
to as thermophoresis. In contrast to particles with a
spherical shape, we show that elongated colloids may have a
thermophoretic response that varies with the colloid
orientation. Remarkably, this can translate into a
non-vanishing thermophoretic force in the direction
perpendicular to the temperature gradient. Opposite to the
friction force, the thermophoretic force of a rod oriented
with the temperature gradient can be larger or smaller than
when oriented perpendicular to it. The precise anisotropic
thermophoretic behavior clearly depends on the colloidal rod
aspect ratio, and also on its surface details, which
provides an interesting tunability to the devices
constructed based on this principle. By means of mesoscale
hydrodynamic simulations, we characterize this effect for
different types of rod-like colloids.},
