Thermophoresis in colloidal suspensions

This is the authors' abstract. We don't add key points for this paper.

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 diffusiophoresis in colloidal suspensions, it is, both experimentally and theoretically, a challenging subject. Rather than being a comprehensive recollection, this review aims to be a re-examination of the experimental and theoretical tools used to investigate , and of some recent relevant results that may unravel novel aspects of colloid forces. The perspectives of thermophoresis as a tool for particle manipulation in microfluidics are also emphasized.
